Highlights of GAO-07-780, a report to the Committee on Armed Services, 
U.S. Senate and the Committee on Armed Services, House of 
Representatives.

Why GAO Did This Study:

Congress has repeatedly expressed concerns about the pace of military 
operations and 10 U.S.C. §487 requires that the Department of Defense 
(DOD) annually report on personnel tempo—the time service members spend 
away from home. Section 345 of the John Warner National Defense 
Authorization Act for Fiscal Year 2007 directed GAO to report on a 
number of Army and Marine Corps issues. For this report GAO addresses 
the extent to which (1) changes in mobilization and deployment policies 
have affected reserve component availability and provided an approach 
to meet the requirements for the global war on terrorism; and, (2) DOD, 
the Army, and the Marine Corps have collected, maintained, and reported 
complete and accurate personnel tempo data. To address these 
objectives, GAO analyzed data from DOD’s Personnel Tempo and 
Contingency Tracking System databases, and interviewed agency officials.

What GAO Found:

On January 19, 2007, the Secretary of Defense issued a memorandum which 
changed mobilization and deployment policies and increased reserve 
component availability, making virtually all reserve component 
personnel available on an indefinitely recurrent basis under a long-
term approach for meeting the requirements for the global war on 
terror. Previously, involuntary reserve component mobilizations for the 
global war on terrorism were limited to 24 cumulative months; there is 
no cumulative time limit on involuntary mobilizations under the new 
policy. DOD’s new policies provide for an integrated approach to manage 
the long-term requirements for the global war on terrorism while 
addressing issues that had previously been addressed in a piecemeal 
fashion. The new policies emphasize the importance of deployment 
predictability and unit cohesion and they contain deployment rotation 
goals, which differ between the active and reserve components. In 
taking this long-term approach, DOD has recognized that it will not be 
able to immediately achieve its rotation goals and some units will be 
remobilized sooner than the standard. Therefore, the Secretary also 
directed that a program be established to compensate service members 
who are required to mobilize or deploy early or often or extend beyond 
the established rotation policy goals. 

DOD has reported personnel tempo data to Congress and the President 
since 2001, but the reports have not been complete and accurate because 
the Army and Marine Corps do not have quality controls in place to 
ensure the accuracy and completeness of the reports’ underlying data. 
In October 2001, DOD waived two statutory personnel tempo requirements 
due to national security interests. As permitted by the statutes, DOD 
waived the high-deployment payment provision and the management of 
deployments which approach or exceeded certain thresholds. With the 
provisions waived, two mechanisms that would identify faulty personnel 
tempo data were no longer in place, and the services lacked any other 
quality control procedures to ensure the accuracy of the data they were 
collecting and sending to DOD. Despite DOD guidance requiring complete 
and accurate personnel tempo data, service reviews have found that the 
collection and tracking of tempo data have not been accurate. In 2005, 
the Army Human Resources Command reported that personnel tempo was not 
properly recorded for 72 percent of forward-deployed soldiers. In 
fiscal years 2005 and 2006, Marine Corps inspection teams found that 
inspected commands did not have procedures in place to ensure that 
personnel tempo information was accurately reported. DOD’s focus on 
collecting deployment data for ongoing operations has shifted its 
attention away from personnel tempo reporting and DOD recently sent a 
proposal to Congress to modify the definition of deployments. If 
approved, the new definition would be used to revise personnel tempo 
thresholds and related compensation. Until DOD establishes quality 
control procedures, Congress and users of DOD’s personnel tempo data 
need to use caution because they cannot be assured that the data fully 
and accurately reflect service members’ actual tempos.

What GAO Recommends:

GAO recommends that the Secretary of Defense direct the Army and Marine 
Corps to develop quality control procedures for validating the accuracy 
of service member personnel tempo data. In commenting on a draft of 
this report, DOD concurred with the recommendation.

Congress has repeatedly expressed concerns about the pace of military 
operations; and since 2001, approximately 931,000 U.S. Army and Marine 
Corps service members have deployed for military operations abroad in 
support of the Global War on Terrorism, including approximately 312,000 
Guard and Reserve members. Prior to the Global War on Terrorism, 
concerns about the negative effects on individual service members or 
service readiness led Congress to place statutory limits on the numbers 
of reserve component personnel who could be involuntarily called to 
active duty under various mobilization authorities, as well as time 
limits on involuntary activations. Recently, in the National Defense 
Authorization Act for Fiscal Year 2000 (FY 2000 NDAA), Congress enacted 
several provisions addressing personnel tempo.[Footnote 1] Title 37 of 
the U.S. Code was amended with the addition of a section requiring the 
secretaries of the military services to pay high-deployment 
compensation payments to service members for lengthy or numerous 
deployments in excess of set limits.[Footnote 2] A section was added to 
Title 10 of the U.S. Code requiring management of deployments of 
service members in danger of exceeding high-deployment days 
thresholds.[Footnote 3] Sections were added to Title 10 of the U.S. 
Code requiring the Secretary of Defense to include personnel tempo 
information in his annual report to the President and Congress[Footnote 
4] and making the Under Secretary of Defense for Personnel and 
Readiness (OSD P&R) responsible for monitoring personnel tempo and 
establishing related standards and policies, subject to the authority, 
direction and control of the Secretary of Defense.[Footnote 5]

The provisions requiring high-deployment compensation payments and 
management of service member deployments allow the waiver of those 
sections if necessary for the national security interests of the United 
States. In October 2001, the Deputy Secretary of Defense issued a 
memorandum that waived those two provisions due to the national 
emergency declared by the President following the September 11th 
attacks on the Pentagon and the World Trade Center. The memorandum 
stated that the requirements for tracking and reporting of personnel 
tempo information would not be waived, and explained that past 
operations have shown the value of collecting this type of data to 
develop after-action reports, reply to queries, or accomplish analysis 
relating to the scope of operations.

Since then, the Department of Defense (DOD) has issued a variety of 
policies that directly and indirectly affect personnel tempo and on 
January 19, 2007, the Secretary of Defense issued a memorandum that 
contained revised policies for managing the total active and reserve 
component force. DOD has also proposed that Congress approve a change 
to the definition of deployment, which would impact the days of service 
that could be counted for purposes of calculating personnel tempo, and 
has said that if the definitional change is approved it will work with 
the military departments to develop high-deployment thresholds and 
compensation proposals that are more closely tailored to the individual 
services' deployment cycles rather than having a single set of 
thresholds for all services.

In the John Warner National Defense Authorization Act for Fiscal Year 
2007,[Footnote 6] Congress required that the Comptroller General issue 
one or more reports assessing the readiness of Army and Marine Corps 
ground forces due to the significant deployments under current 
operational commitments and other demands. Specifically, the act 
required that the Comptroller General's reports include analyses of 
Army and Marine Corps reported readiness trends, the ability of the 
Army and Marine Corps to provide trained and ready forces for ongoing 
operations and other commitments, the availability of equipment for 
training, current and projected requirements for equipment repair and 
replacement and the effects on training, personnel tempos including 
trends and retention data for enlisted occupations with unusually high 
or low deployment rates, efforts to mitigate the impact of high 
operational tempo, and the effect of current mobilization policies on 
reserve component force availability. This report assesses (1) the 
extent to which changes in mobilization and deployment policies have 
affected reserve component availability and provided an approach to 
meet the requirements for the global war on terrorism, and (2) the 
extent to which DOD, the Army, and the Marine Corps have collected, 
maintained, and reported complete and accurate personnel tempo data. We 
are also providing information on trends in personnel tempo (see app. 
I), and retention/attrition rates for Army and Marine Corps personnel 
in enlisted occupational specialties that are experiencing unusually 
high or low deployment rates (see app. II). We are not drawing any 
conclusions concerning relationships between deployment and retention 
because deployment rates are not the only factor that can affect 
retention or attrition. Appendix II identifies some of the other 
factors that influence service member retention decisions, or 
attrition. We are reporting separately on the other readiness reporting 
requirements included in the John Warner National Defense Authorization 
Act for Fiscal Year 2007.

To assess the extent to which changes in mobilization and deployment 
policies have affected reserve component availability and provided an 
approach to meet the requirements for the global war on terrorism, we 
reviewed and analyzed past and present DOD mobilization and deployment 
policies as well as requirements for the global war on terrorism, 
comparing the effects of policies before and after Secretary Gates' 
January 19, 2007, memorandum regarding the utilization of the total 
force. We also interviewed officials who are responsible for the 
implementation of personnel policies. To assess the extent to which 
DOD, the Army, and the Marine Corps have collected, maintained, and 
reported complete and accurate personnel tempo data, we interviewed and 
obtained data from Office of the Secretary of Defense (OSD), Army, 
Marine Corps, and Defense Manpower Data Center (DMDC) officials who 
collect and track personnel tempo and deployment data. To provide the 
data in the appendices on trends in personnel tempo and retention rates 
for Army and Marine Corps personnel in enlisted occupational 
specialties that are experiencing unusually high or low deployment 
rates, we analyzed data from three DMDC data systems--the PERSTEMPO, 
Contingency Tracking System (CTS), and end strength data systems 
(Active Duty Military Personnel Master File and the Reserve Components 
Common Personnel Data System). For the personnel tempo analyses, we 
used PERSTEMPO and end strength data to identify the yearly end 
strength population, the population of deployed personnel, and 
cumulative days deployed. Additionally, we reviewed inspection reports 
related to personnel tempo and DOD's Annual Reports to Congress and the 
President. To determine retention rates for Army and Marine Corps 
personnel in enlisted occupational specialties that are experiencing 
unusually high or low deployment rates, we used the CTS and end 
strength data to determine the enlisted occupational specialties that 
had unusually high or low deployment rates. We then obtained retention 
data on these occupations from DMDC. We assessed the reliability of the 
three DMDC data systems and determined that the CTS and end strength 
data we used were reliable for our purposes. We determined the 
PERSTEMPO data was not producing reliable personnel tempo summaries and 
trends. Consequently, we did not use PERSTEMPO data to support findings 
or recommendations, and in order to meet legislative requirements, we 
report these data only in appendix I, along with the associated data 
reliability caveats. For more information on our scope and methodology, 
see appendix III. We conducted this performance audit from June 2006 
through May 2007 in accordance with generally accepted government 
auditing standards.

Results in Brief:

On January 19, 2007, the Secretary of Defense issued a memorandum which 
changed mobilization and deployment policies and increased reserve 
component availability, making virtually all reserve component 
personnel available on an indefinitely recurrent basis under a long- 
term approach for meeting the requirements for the global war on 
terrorism. Prior to this memorandum, service member availability was 
restricted by a DOD policy which limited involuntary mobilizations for 
the global war on terrorism to 24 cumulative months. The Secretary's 
memo and the implementing guidance that followed in March 2007 
rescinded the 24-cumulative-month limitation and provided the services 
with much greater access to their reserve component personnel for the 
long-term requirements of the global war on terrorism. For example, as 
of August 31, 2006, almost 421,000 reserve component personnel had been 
activated and had limited availability for future involuntary 
mobilizations under the 24-cumulative-month policy, but when the policy 
was rescinded, previously mobilized personnel became available for 
future involuntary mobilization without any limitations on their 
cumulative service. As a result of the new policy, involuntary 
mobilizations, which will generally be limited to 12 months,[Footnote 
7] can now recur indefinitely. In addition, the new implementing 
guidance replaces the prior policies that were issued in a piecemeal 
fashion to address short-term requirements with an integrated set of 
policies that governs access to active as well as reserve component 
personnel. The previous policies had emphasized the use of volunteers, 
but the new policies emphasize the importance of maintaining unit 
cohesion and deployment predictability. The new policies contain 
rotation goals which differ between the active and reserve components. 
While the new policies provide a long-term approach for meeting 
requirements, both the Secretary's memo and the implementing guidance 
acknowledge that the services will not be able to immediately achieve 
the rotation goals, due to global demands. Therefore, the Secretary's 
memo directed the establishment of a program to compensate or 
incentivize service members who are required to mobilize or deploy 
early or often, or to extend beyond the established rotation policy 
goals.

Since 2001, DOD has reported personnel tempo data in its "Annual 
Defense Report to the President and the Congress", but the reports have 
not been complete and accurate because the Army and Marine Corps do not 
have quality controls to ensure the accuracy and completeness of the 
reports' underlying data. In October 2001, DOD waived two provisions 
related to personnel tempo due to national security interests, but the 
requirement to report personnel tempo data to the President and 
Congress remained in place. As permitted by 37 U.S.C. §436 and 10 
U.S.C. §991, DOD waived the high-deployment compensation requirement 
and the requirement to manage service member deployments which approach 
or exceeded high-deployment thresholds. When these provisions were 
waived, two of the mechanisms for identifying faulty personnel tempo 
data were no longer in place, and the services lacked any other quality 
control procedures to effectively ensure the accuracy of the data they 
were collecting and sending to DOD. Despite DOD guidance which requires 
personnel tempo data to be complete and accurate, several reviews have 
found that service collection and tracking of personnel tempo data have 
not been complete or accurate. For example, in 2005 the Army Human 
Resources Command reported that personnel tempo was not properly 
recorded for 72 percent of forward-deployed soldiers, and Marine Corps 
inspection teams found that 43 percent of the 326 active and reserve 
units they inspected in fiscal years 2005 and 2006 had not consistently 
or accurately reported personnel. Furthermore, DOD officials expressed 
a low level of confidence in the data and said that they relied on an 
alternative set of data to examine tempo trends. Shortly after the 
September 11, 2001, attacks, DOD shifted its attention away from 
collecting and maintaining personnel tempo data and began focusing on 
collecting and maintaining data to track activations and deployments 
related to ongoing operations.[Footnote 8] In addition, DOD recently 
sent a proposal to Congress requesting a modification to the deployment 
definition, which if approved would modify personnel tempo calculations 
and allow DOD to develop revised high-deployment thresholds and 
compensation programs that are tailored to individual service 
deployment cycles. However, DOD officials have stated that neither DMDC 
nor the services have the complete and accurate data needed to 
effectively implement a personnel tempo compensation program. Without 
quality control procedures, personnel tempo data could not be used as 
an accurate basis to determine eligibility for the high-deployment 
payment program under 37 U.S.C. §436, or for the revised high- 
deployment compensation program that DOD has recently proposed to 
Congress. Until the Army and Marine Corps establish quality control 
procedures for the collection of their personnel tempo data, Congress 
and other users of DOD's personnel tempo data need to be cautious when 
using the data because they cannot be assured that the data fully and 
accurately reflect service members' actual tempos.

To improve the accuracy and comprehensiveness of the personnel tempo 
data that DOD reports to Congress and the President, we are 
recommending that the Secretary of Defense direct the Undersecretary of 
Defense for Personnel and Readiness to provide guidance which directs 
the Army and Marine Corps to develop quality control procedures for 
ensuring the accuracy of the personnel tempo data they collect and 
report, whether under the existing personnel tempo definition or under 
any revised definitions that Congress may approve. In its comments on a 
draft of this report, DOD concurred with our recommendation. DOD also 
provided technical comments, which we have incorporated in the report 
as appropriate. DOD's comments and our evaluation are reprinted in 
their entirety in appendix IV of this report.

Background:

Reserve Mobilization:

Reserve forces may be called to active duty under a number of 
authorities. Most reserve component members who have been called to 
active duty for other than normal training since September 11, 2001, 
have been activated under one of the three legislative 
authorities[Footnote 9] listed in table 1.

Table 1: Mobilization Authorities:
Statute: 10 U.S.C. §12301 (d); "With members consent"; 
Type of activation: Voluntary; 
Maximum number of Ready Reserve members who can be activated at once: 
Unlimited; 
Maximum length of activation: Unlimited.

Statute: 10 U.S.C. §12302; "Partial Mobilization"; 
Type of activation: Involuntary; 
Maximum number of Ready Reserve members who can be activated at once: 
1,000,000; 
Maximum length of activation: 730 days/24 consecutive months.

Statute: 10 U.S.C. §12304; "Presidential Reserve Call-up"; 
Type of activation: Involuntary; 
Maximum number of Ready Reserve members who can be activated at once: 
200,000; 
Maximum length of activation: 365 days/12 consecutive months.

[End of table]

On September 14, 2001, the President declared that a national emergency 
existed as a result of the attacks of September 11, 2001, and he 
invoked 10 U.S.C. §12302, the partial mobilization authority. When DOD 
issued subsequent guidance concerning the partial mobilization 
authority,[Footnote 10] it limited mobilization orders to 12 months but 
allowed the secretaries of the military departments to extend the 
orders for an additional 12 months or remobilize reserve component 
members, as long as an individual member's cumulative service under the 
partial mobilization authority did not exceed 24 cumulative months. The 
guidance also allowed the services to keep members on active duty after 
they had served 24 months under the partial mobilization authority if 
the member volunteered to stay on active duty under 10 U.S.C. § 
12301(d).

In 2004, we reported[Footnote 11] that the 24-cumulative-month approach 
and other policies developed at the war's outset had affected the 
availability of Army and Marine Corps reservists for second involuntary 
mobilizations.[Footnote 12] The report concluded that adhering to the 
24-cumulative-month policy amid persistently high requirements could 
result in the services running out of reservists eligible and available 
for a second involuntary mobilization. Moreover, we stated that DOD's 
policies, many of which emphasized the use of volunteers, were 
implemented in piecemeal fashion, responding to the short-term 
requirements of the services and the needs of reserve component 
members, and were not developed within an overall strategic framework 
to meet the department's long-term requirements for the global war on 
terrorism. We concluded that given the duration of operational 
commitments to date (2004) and the likelihood for persistently high 
force-level requirements into the future, the department needed to 
develop an integrated set of policies to address both the long-term 
requirements for reserve component forces and individual reserve 
component members' needs for predictability. After assessing DOD's 
policies regarding the management and deployment of reserve component 
service members, the Secretary of Defense enacted changes to reserve 
mobilization policy with his January 19, 2007, total force policy 
memorandum.

Personnel Tempo:

Personnel tempo is currently defined as the amount of time members of 
the armed forces are engaged in their official duties, at a location or 
under circumstances that make it infeasible for a member to spend off- 
duty time in the housing in which the member resides when on garrison 
duty at the member's permanent duty station.[Footnote 13] Title 10 of 
the U.S. Code contains a number of provisions related to personnel 
tempo including a provision which requires the secretary of each 
military department to establish a system for tracking and recording 
the number of days that each member of the armed forces under that 
secretary's jurisdiction is deployed.[Footnote 14] There is also a 
provision that requires management of service members' deployments 
which approach or exceed high-deployment thresholds.[Footnote 15] In 
addition, since October 1, 2000, the Secretary of Defense has been 
required to include personnel tempo information in his annual report to 
the President and Congress.[Footnote 16]

Title 37 of the U.S. Code contains a requirement for DOD to compensate 
service members who exceed legislatively established deployment 
thresholds.[Footnote 17] At the time the provision was created by the 
FY 2000 NDAA, the services were to pay a per diem allowance of $100 to 
members who deployed for more than 250 days out of the previous 365. 
Later, the National Defense Authorization Act for Fiscal Year 2004 (FY 
2004 NDAA[Footnote 18]) modified the high-deployment thresholds and pay 
provisions, replacing the per diem allowance with a monthly allowance 
of up to $1,000, payable for any month in which a member is beyond the 
new high-deployment thresholds[Footnote 19] by at least 1 day.

In May 2001, OSD P&R issued a military personnel record instruction 
which updated responsibilities, procedures, and information-reporting 
requirements including personnel tempo reporting.[Footnote 20] 
According to the instruction, all services are to submit personnel 
tempo data to the Defense Manpower Data Center (DMDC), which serves as 
the central repository and archive for automated manpower and personnel 
information for DOD. The instruction requires that the services report 
timely, accurate, and complete personnel tempo data. The Army and 
Marine Corps each issued further implementing guidance based on the OSD 
instruction.

On October 8, 2001, the Deputy Secretary of Defense issued a memorandum 
in accordance with waiver provisions found in 10 U.S.C. §991 and 37 
U.S.C. §436, suspending the requirement to compensate service members 
who exceeded the personnel tempo threshold due to the existence of a 
national emergency declared by the President. Additionally, the 
memorandum suspended the statutory requirement for management of 
service member deployments which approached or exceeded high-deployment 
thresholds. The memorandum did not suspend the requirement for services 
to collect and submit personnel tempo data, and stated that past 
operations have proven that collection of these data is valuable in 
developing after action-reports, replying to queries, or accomplishing 
analyses relating to the scope of operations.

Virtually All Reserve Component Personnel Are Available Under DOD's 
Revised Policies that Provide a Long-Term Approach to Meet Mobilization 
Requirements:

On January 19, 2007, the Secretary of Defense issued a memorandum that 
changed mobilization and deployment policies and increased reserve 
component availability, making virtually all reserve component 
personnel available on an indefinitely recurrent basis. The memorandum 
and subsequent implementing guidance also established a long-term 
approach for meeting the requirements for the global war on terrorism 
while striving to provide service members with increased 
predictability. Additionally, DOD recently established a program to 
compensate service members who are required to mobilize or deploy early 
or often, or to extend beyond established rotation policy goals.

Virtually All Reserve Component Members Are Available for Deployment 
Under New Mobilization Policies:

The Secretary of Defense's January 19, 2007, total force policy 
memorandum and the subsequent March 15, 2007, implementation policy 
guidance made virtually the entire reserve component force available 
for mobilization and deployment.[Footnote 21] Prior to the Secretary's 
memorandum, service member availability was restricted by a DOD policy 
which limited involuntary mobilizations for the global war on terrorism 
to 24 cumulative months. Under the prior policy, any service member who 
had been involuntarily mobilized for 24 months was no longer available 
to the services for involuntary mobilization. According to DOD data, 
almost 421,000 reserve component personnel were currently activated or 
had been previously activated as of August 31, 2006. These personnel 
would not have been available for involuntary mobilizations, or would 
have had limited availability under the prior policy.[Footnote 22] 
However, when the Secretary's memo and the implementing guidance 
rescinded the 24-cumulative-month limitation all of these personnel 
became available for involuntary mobilizations. The revised policies 
provide the services with much greater access to their reserve 
component personnel for the long-term requirements of the global war on 
terrorism because they allow for repeat involuntary mobilizations, 
without limitations on the cumulative time a service member is 
mobilized. The new guidance allows DOD to mobilize reserve component 
individuals for a period of time--generally no more than 12 months at a 
time, send them home, and then remobilize them, repeating this cycle 
indefinitely and providing an essentially unlimited flow of forces, 
within the 1 million service member and 730 consecutive day limitations 
of the partial mobilization authority.[Footnote 23]

Mobilization Policy Changes Establish a Long-Term Approach for Meeting 
the Global War on Terrorism Requirements:

DOD's current mobilization policies differ from prior policies because 
the Secretary's memorandum and the corresponding implementation 
guidance provide DOD with an integrated approach for managing the use 
of active and reserve component personnel in meeting the long-term 
requirements of the global war on terrorism. In 2004 GAO 
reported[Footnote 24] that DOD's mobilization and personnel policies 
had been implemented in a piecemeal fashion to address short-term 
requirements and as a result reserve component personnel were uncertain 
about the likelihood of mobilizations, the length of service 
commitments, the length of overseas rotations, and the types of 
missions they would perform.

The Secretary's January 2007 memorandum and the March 2007 implementing 
guidance helped address the need for predictability while giving the 
services flexibility to meet long-term requirements. For example, the 
documents specified that future mobilizations of ground combat, combat 
support, and combat services support would be managed on a unit basis 
to allow greater cohesion and deployment predictability. The 
implementing guidance also indicated that the secretaries of the 
military departments would determine the best method for filling unit 
shortfalls. This decentralized decision authority represents a 
departure from the previous centralized policy guidance that called for 
using volunteers before involuntarily mobilizing Individual Ready 
Reserve members or remobilizing previously mobilized Selected Reserve 
members.[Footnote 25] The current guidance states that options for 
filling unit shortfalls could include, but would not be limited to, 
using volunteers including retirees, involuntary call-ups of Individual 
Ready Reserve and Inactive National Guard, or integrating active 
component members.

Overall, the memorandum and implementation guidance presented a 
substantial revision to preceding reserve mobilization policies, 
stating that the services would plan for a protracted war on terrorism 
by effectively managing their manpower resources. The single set of 
guidance provided an integrated approach for meeting long-term 
requirements and addressed the full range of policy issues that had 
previously been addressed in a piecemeal fashion. For example, the 
issues addressed in the March 2007 policy guidance included the length 
of mobilization orders, extensions, early releases from orders, the use 
of the Individual Ready Reserve, and exemptions from training following 
deployments.

The new guidance specifies that future involuntary mobilizations will 
generally be limited to 12 months, with possible service exceptions for 
individual skill training required for deployment and postmobilization 
leave, and other exceptions if approved by the Secretary of Defense. 
The documents also set rotation policy goals for both reserve and 
active component personnel. These goals can differ between the active 
and reserve components and among services.[Footnote 26] While these 
rotation policies provide a long-term approach for meeting 
requirements, both the Secretary's memo and the implementing guidance 
acknowledge that the services will not be able to immediately achieve 
the rotation goals, due to global demands. The Secretary's memo 
explicitly states that global demands will require some units to be 
remobilized sooner than the standard. Therefore, the memo directed the 
establishment of a program to compensate or incentivize service members 
who are required to mobilize or deploy early or often, or to extend 
beyond the established rotation policy goals.

On April 18, 2007, DOD announced that administrative absences would be 
awarded to service members who are required to mobilize or deploy with 
a frequency that exceeds established rotation policy goals. The 
absences will be distinct from normal leave accrued by service members. 
They will be awarded when service member deployments exceed 
mobilization and deployment planning objectives---that is, twice as 
much time at home as deployed for the active component, and five times 
as much time at home as mobilized for the reserve component.[Footnote 
27] In addition to the administrative absences, some service members 
could eventually receive monetary compensation for these deployments or 
mobilizations if they cause the service member to exceed certain 
thresholds under broader personnel tempo definitions.

Since 2001, DOD Has Submitted Personnel Tempo Reports but the Army and 
Marine Corps Lack Quality Controls to Ensure the Accuracy of Underlying 
Data:

Since 2001, DOD has reported personnel tempos in its "Annual Defense 
Report to the President and the Congress", but the reports have not 
been complete or accurate because the Army and Marine Corps do not have 
quality controls in place to ensure the accuracy and completeness of 
the reports' underlying data. In addition, DOD's focus on collecting 
deployment and activation data for ongoing operations has shifted 
attention away from personnel tempo tracking and reporting.

Since 2001, DOD Has Reported Personnel Tempo Data to the President and 
Congress:

As directed by 10 U.S.C. §991, the services began collecting personnel 
tempo data in fiscal year 2000; and since 2001, DOD has published 
personnel tempo data in an appendix to "The Annual Defense Report to 
the President and the Congress" as required by 10 U.S.C. §487. The 
reported data covered fiscal years 2001 through 2005 and the personnel 
tempo appendixes have generally included the types of figures that are 
required by the law--service and component end strengths, the 
populations of deployed personnel, and average personnel tempos (in 
days) among the deployed populations or the total end strength 
populations. Other information related to personnel tempos has also 
been reported on a sporadic basis. For example, in 2001 and 2002, the 
appendices included the number of days "high demand/low density" units 
deployed but this information was not included in unclassified versions 
in later years.

The Army and Marine Corps Lack Quality Controls to Accurately Collect 
Personnel Tempo Data:

With the suspensions of the high-deployment compensation requirement 
and the requirement for management of service member deployments that 
approach or exceed high-deployment thresholds, no service members have 
received personnel tempo payments and a key quality control mechanism 
has been missing for more than 5 years.[Footnote 28] The suspensions 
have removed two mechanisms that could have identified faulty personnel 
tempo data and the Army and Marine Corps lack other quality control 
procedures for effectively ensuring the accuracy of the data they 
collect and send to DOD. According to various DOD and service 
officials, quality checks on the data only occur if service members 
check the accuracy of their own personnel tempo data. Service members 
have several opportunities to review their personnel tempo records, 
such as when they transfer between commands or separate from the 
service, but the likelihood that they will actually do so is low 
because there is no incentive to do so. A 2005 III Corps Inspector 
General report found that fewer than 25 percent of the units inspected 
included personnel tempo reporting and tracking procedures as part of 
their in-and out-processing procedures. Furthermore, the Inspector 
General report found that the office responsible for personnel policy 
did not publish personnel tempo management guidance in a timely manner.

Since the suspension of the high-deployment compensation and deployment 
management provisions, several reviews have found that the services' 
collection and tracking of personnel tempo data have not been complete 
or accurate, even though the requirement to report tempo data to the 
President and Congress has remained in place. For example, in 2005 the 
Army Human Resources Command reported that for 72 percent of forward- 
deployed soldiers, personnel tempo was not properly recorded in the 
Electronic Military Personnel Office, the Army's online integrated 
personnel reporting system. In addition, Marine Corps inspection teams 
recently concluded that inspected commands did not have procedures in 
place to ensure that personnel tempo information was reported. Of the 
326 active and reserve units inspected in fiscal years 2005 and 2006, 
43 percent had not consistently or accurately reported personnel tempo 
in the Marine Corps Total Force System, the service's integrated 
personnel database.[Footnote 29]

DOD Has Focused on Deployment and Activation Data Rather than on 
Personnel Tempo Data:

Shortly after the September 11, 2001, attacks, DOD shifted its focus 
away from collecting and maintaining personnel tempo data and began 
focusing on collecting and maintaining data to track activations and 
deployments related to major operations.[Footnote 30] This data 
collection for Operations Noble Eagle, Enduring Freedom, and Iraqi 
Freedom does not include the full range of personnel tempo events that 
are listed in 10 U.S.C. §487. The increased priority on data related to 
global war on terrorism deployments diminished the level of effort 
given to personnel tempo data collection and the quality of the data 
collected.

The October 2001 memorandum that suspended the high-deployment 
compensation and deployment management provisions did not suspend the 
requirement for the services to collect and submit personnel tempo 
data. It stated that deployment data tracking and reporting remained a 
priority, as previous operations had proven that such efforts were 
valuable for developing after-action reports and completing analyses 
related to the scope of operations.

Subsequent DOD and service guidance reiterated the requirement to 
continue reporting personnel tempo information for service members 
mobilized or deployed in support of the global war on terrorism, and 
the DOD guidance required that personnel tempo data reporting be 
timely, accurate, and complete. Despite this guidance, DOD officials 
expressed a low level of confidence in the quality of the personnel 
tempo data that have been collected. They told us that they routinely 
rely on an alternative set of data from DMDC to examine tempo trends 
and they noted that DMDC can conduct only limited quality control on 
personnel tempo data, because DMDC is responsible only for compilation 
and does not have the resources to identify anomalies in data provided 
by the services. The services are responsible for collecting personnel 
tempo data and although both the Army and Marine Corps issued 
implementing guidance based on the OSD instruction, which required 
timely, accurate, and complete reporting of personnel tempo data, the 
implementing guidance did not contain quality control procedures to 
ensure complete and accurate personnel tempo data are collected and 
transmitted to DMDC.

In February 2007, DOD submitted a proposal to Congress to modify the 
deployment definition.[Footnote 31] The proposal would maintain the 
basic definition of deployments but would narrow the scope to exclude 
non-operational temporary duty including absences for conferences and 
training and participation in training or exercises designated by the 
secretaries of the military departments. A change in the definition of 
deployment would impact personnel tempo calculations by changing the 
days that could be counted for purposes of personnel tempo. If the 
proposal is approved, DOD will work with the military departments to 
develop revised high-deployment thresholds and compensation proposals 
that are more closely tailored to individual service deployment cycles. 
However, without quality controls on the collection of Army and Marine 
Corps data, DOD officials have stated that neither DMDC nor the 
services have the complete and accurate data needed to effectively 
implement a personnel tempo compensation program.

Conclusions:

Since the onset of the global war on terrorism, the Army and Marine 
Corps have deployed approximately 931,000 of their service members for 
military operations abroad. Facing limitations on its available reserve 
component forces, DOD recently instituted an integrated set of policies 
that provides it with increased access to its reserve component forces 
as it plans for a long-term global war on terrorism. Although the new 
policies will better position the services to meet their long-term 
requirements, current global demands are making it difficult for the 
services to meet rotation goals in the short term. Faced with these 
challenges, the management of personnel tempo is critical as DOD 
strives to retain a quality force for the future. However, the Army and 
Marine Corps have not maintained complete and accurate personnel tempo 
data and they do not have quality control procedures in place to ensure 
the accuracy of their personnel tempo data. Furthermore, the high- 
deployment compensation and deployment management provisions which 
could have helped to identify faulty data have been waived for national 
security reasons since 2001. Without quality control procedures to 
ensure the completeness and accuracy of personnel tempo data, the data 
could not be used as an accurate basis to determine eligibility for the 
current high-deployment compensation programs found in Title 37 of the 
U.S. Code or for an alternative compensation program based on DOD's 
recent legislative proposal. Until the Army and Marine Corps establish 
quality control procedures for the collection of their personnel tempo 
data, Congress and others need to be cautious when using DOD's 
personnel tempo data because they cannot be assured that the data fully 
and accurately reflect service members' actual tempos.

Recommendations for Executive Action:

To improve the accuracy and comprehensiveness of the personnel tempo 
data that DOD reports to Congress and the President, we recommend that 
the Secretary of Defense direct the Undersecretary of Defense for 
Personnel and Readiness to provide guidance which directs the Army and 
Marine Corps to develop quality control procedures for validating the 
accuracy of the personnel tempo data they collect and report to DMDC, 
whether under the existing personnel tempo definition or under any 
revised definitions that Congress may approve.

Appendix I: Army and Marine Corps Personnel Tempo Trends Based on 
Available Data:

According to the 2005 Annual Defense Report to the President and the 
Congress, personnel tempos for the Army and the Marine Corps increased 
significantly between fiscal year 2001 and fiscal year 2003 and then 
the rates declined slightly in fiscal year 2004. At the time of our 
report, the Department of Defense (DOD) had not released the 2006 
Annual Defense Report to the President and the Congress, which would 
have contained 2005 personnel tempo data.

DOD has reported two measures of personnel tempo. The first divides the 
total number of days deployed under the personnel tempo definition by 
the total end strength of each service or service component. The second 
also begins with the total number of days deployed under the personnel 
tempo definition but divides this figure only by the number of 
personnel who were actually deployed during the fiscal year. Table 2 
shows Army and Marine Corps personnel tempo figures as reported in the 
2005 Annual Defense Report to the President and the Congress. However, 
as discussed earlier in this report, we determined that DOD's personnel 
tempo (PERSTEMPO) data may not produce reliable personnel tempo 
summaries and trends because the Army and Marine Corps lack quality 
control procedures for collecting these data and reporting them to 
Defense Manpower Data Center (DMDC).

We also performed our own analysis of DMDC's PERSTEMPO data. This 
analysis of PERSTEMPO data shows that the Army personnel tempo average 
rose substantially from fiscal year 2002 to fiscal year 2004 and then 
rose more slowly in fiscal year 2005 and fiscal year 2006. In contrast, 
the Marine Corps personnel tempo average peaked in fiscal year 2003. 
Table 3 shows the results of our analysis.

[End of table]

Our analysis shows similar trends to the trends from the 2005 Annual 
Defense Report to the President and the Congress. However, there are 
differences in figures, which may be attributed to differences in data 
analysis assumptions. (See app. III for additional information 
concerning the methodology for our analysis.) In addition, our analysis 
includes fiscal years 2005 and 2006 but it does not include fiscal year 
2001 data. Finally, our analysis is subject to the same major 
limitation as the trend information from the Annual Defense Report 
because our data were drawn from the same source that was found to be 
incomplete or inaccurate because the Army and Marine Corps lack quality 
control procedures for collecting these data and reporting them to DMDC.

Appendix II: Retention/Attrition Rates for Enlisted Occupational 
Specialties with Unusually High or Low Deployment Rates:

This appendix responds to the requirement that we identify enlisted 
occupational specialties that are experiencing unusually high or low 
deployment rates and analyze retention rates for those occupational 
specialties.[Footnote 32] The Department of Defense (DOD) collects and 
tracks retention data for its active component forces but it uses 
attrition rather than retention data in managing its reserve component 
forces. This appendix contains retention/attrition rate data for 
enlisted occupational specialties that have experienced unusually high 
or low deployment rates, but it does not attempt to make any 
conclusions concerning relationships between deployment and retention 
or attrition rates because other factors, beyond deployment, can affect 
retention. Specifically, previous studies and surveys have indicated 
that in addition to deployments, a wide variety of other factors 
influence service members' decisions regarding whether or not to stay 
in the military. Some of these factors include basic pay, reenlistment 
bonuses, family medical care, quality of leadership, and civilian 
career opportunities.

Service Retention and Attrition Tracking:

The Army tracks retention rates by initial term (first enlistment, 
regardless of length), mid-career (second or subsequent enlistments up 
to 10 years of service), and career (10 or more years of service). The 
Marine Corps tracks retention by first enlistment and second or 
subsequent enlistment. DOD tracks National Guard and Reserve attrition 
rates, which are defined as the number of service members who leave 
those components in a given year divided by the components' average 
strength as measured at the beginning of the fiscal year and at the end 
of that fiscal year.

Enlisted Occupational Specialties with Unusually High or Low Deployment 
Rates:

To determine which enlisted occupational specialties had unusually high 
or low deployment rates, we used several steps. First we obtained 
fiscal year 2001 to fiscal year 2006 data from the Defense Manpower 
Data Center's (DMDC) end strength files and from its Contingency 
Tracking System Deployment file. We then analyzed these files by 
military occupational specialty (MOS), and for each MOS we determined 
the yearly end strength population, the population of deployed 
personnel, the number of days the deployed population could have 
possibly served, and the number of days the deployed population 
actually served.

We then calculated two deployment measures for each occupational 
specialty. First we calculated a days-served ratio by dividing the 
total number of days the deployed population actually served in fiscal 
year 2006 by the number of days they could have possibly served in 
fiscal year 2006. Second we calculated a population ratio by dividing 
the deployed MOS population in fiscal year 2006 by the total MOS 
population in fiscal year 2006. We then calculated the quartiles for 
both the days-served ratio and the population ratio. If both the days- 
served ratio and the population ratio for an occupational specialty 
were in the highest quartile, then the occupational specialty was 
classified as having an unusually high deployment rate. If both 
measures were in the bottom quartile then the occupational specialty 
was classified as having an unusually low deployment rate. After we 
identified the occupational specialties with unusually high and low 
deployment rates, we requested and DMDC provided retention/attrition 
data for each of those specialties for fiscal years 2001 through 2006.

Active Component Retention Rates:

Table 4 shows active component Army and Marine Corps retention rates 
for personnel in occupational specialties with unusually high or 
unusually low deployment rates. For purposes of this table, a person is 
considered retained if, at the end of the year, the person is on active 
duty and holds a primary MOS with the same two first digits as the 
first two digits of the MOS that the person held at the beginning of 
the year.

Source: GAO analysis based on DMDC data.

[A] Several factors can lead to wide fluctuations in retention rates. 
For example, some new occupational specialties have been introduced 
while other specialties have been phased out. In addition, some 
specialties include recruits, trainees, or officer candidates. 
Retention rates for those specialties are very low because personnel 
generally graduate from the programs and are given different 
occupational specialty codes. For clarity in reporting, we are not 
reporting retention rates for these occupational codes or for 
occupations that have been phased out or which had less than 10 
personnel in fiscal year 2006.

Reserve Component Attrition Rates:

Table 5 shows reserve component Army and Marine Corps attrition rates 
for personnel in enlisted occupational specialties with unusually high 
or unusually low deployment rates. For purposes of this table, a person 
is generally considered attrited if, at the end of the year, the person 
is no longer in the Selected Reserve or if the person holds a primary 
MOS where the first two digits differ from the first two digits of the 
MOS that the person held at the beginning of the year.

[A] Several factors can lead to wide fluctuations in attrition rates. 
For example, some new occupational specialties have been introduced 
while other specialties have been phased out. In addition some 
specialties include recruits, trainees, or officer candidates. 
Attrition rates for those specialties are very high because personnel 
generally graduate from the programs and are given different 
occupational specialty codes. For clarity in reporting, we are not 
reporting attrition rates for these occupational codes or for 
occupations that have been phased out or which had less than 10 
personnel in fiscal year 2006.

[End of table]

In examining tables 4 and 5, it is important to note that personnel in 
some high-deploying occupational specialties may not be deploying for 
their chosen specialty. For example, many personnel with field 
artillery occupational specialties have been deployed to perform 
military police or security functions. For these personnel, retention 
decisions may be influenced not only by the factors previously cited 
(basic pay, reenlistment bonuses, family medical care, quality of 
leadership, and civilian career opportunities) but also by the fact 
that they have been deployed and are working outside of their chosen 
occupational specialties. For individual service members these other 
factors may have a larger impact on retention decisions than their 
deployment rates.

Appendix III: Scope and Methodology:

To assess the extent to which changes in mobilization and deployment 
policies have affected reserve component availability and provided an 
approach to meet the requirements for the global war on terrorism, we 
reviewed and analyzed past and present Department of Defense (DOD) 
mobilization and deployment policies as well as requirements for the 
global war on terrorism, comparing the effects of policies before and 
after Secretary Gates' January 19, 2007, memorandum regarding the 
utilization of the total force. Specifically, we discussed the 
implementation of mobilization authorities and the effects of various 
personnel policies with responsible officials from the (1) Assistant 
Secretary of Defense for Reserve Affairs, Arlington, Virginia; (2) 
Under Secretary of Defense for Personnel and Readiness, Arlington, 
Virginia; (3) Joint Chiefs of Staff, Arlington, Virginia; (4) Assistant 
Secretary of the Army for Manpower and Reserve Affairs, Arlington, 
Virginia; and (5) Commandant, Marine Corps (Manpower, Plans, and 
Policy), Quantico Marine Corps Base, Virginia.

In meetings with the Office of Secretary of Defense (OSD), Joint Staff, 
and service officials, we discussed the effects of reserve mobilization 
and deployment policies enacted following the September 11, 2001, 
attacks; the advantages and disadvantages of those policies when 
compared to the policies implemented on and after the January 19, 2007, 
when the Secretary of Defense issued a total force policy memorandum; 
and, the impact of policies on the availability of reserve component 
members for future mobilizations and deployments. We also discussed the 
use of special pays and bonuses as instruments that could encourage 
reserve component members to volunteer for mobilizations that exceeded 
the prior 24-cumulative-month time limitation on involuntary 
mobilizations. Finally, we collected and reviewed data regarding the 
population of previously mobilized reserve component members to 
determine reserve component availability under the prior 24-cumulative- 
month limitation.

To assess the extent to which DOD, the Army, and the Marine Corps have 
collected, maintained, and reported complete and accurate personnel 
tempo data, we reviewed legislation and DOD policies regarding 
personnel tempo; Army, Marine Corps, and DOD systems and procedures for 
collecting and reporting personnel tempo data; and previous inspections 
and reviews of the personnel tempo data.

We examined legislation to identify the definition of personnel tempo 
and related terms; the reporting requirements for DOD and the military 
departments; the assignment of roles and responsibilities; the 
thresholds for identifying high-deploying personnel and the 
corresponding provisions for compensation; and the conditions for 
modifying the personnel tempo provisions or issuing waivers to those 
provisions. We also examined corresponding DOD and service policies 
concerning the collection and management of personnel tempo data. We 
also reviewed DOD's Annual Reports to the President and the Congress, 
which congressional legislation identified as the means for 
transmitting personnel tempo data. We compared and contrasted the DOD 
guidance on personnel tempo and deployment data collection that was 
issued before the personnel tempo oversight and compensation provisions 
were waived in October 2001 to guidance that was issued after the 
waiver.

We also discussed the implementation and efficacy of DOD and service 
personnel tempo and deployment and activation data collection policies 
with responsible officials from the (1) Under Secretary of Defense for 
Personnel and Readiness, Arlington, Virginia, including Military 
Personnel Policy, Arlington, Virginia and Defense Manpower Data Center 
(DMDC West), Seaside, California; (2) Assistant Secretary of Defense, 
Reserve Affairs, Arlington, Virginia; (3) Department of the Army, Human 
Resources Command, including Alexandria, Virginia (Active) and St. 
Louis, Missouri (Reserve); (4) United States Marine Corps, Manpower 
Plans and Policy Division, Quantico Marine Corps Base, Virginia; (5) 
United States Marine Corps, Inspection Division, Office of the 
Inspector General, Quantico Marine Corps Base, Virginia; and (6) 
National Guard Bureau, G-1, Selected Reserve Branch, Arlington, 
Virginia.

We compiled and reviewed documentation on DOD and service evaluations, 
inspections, and reviews of personnel tempo data. In addition, we 
reviewed documentation on the DMDC and service systems used to collect, 
process, and archive personnel tempo and deployment data. Furthermore, 
we reviewed the personnel tempo proposal submitted by OSD to Congress 
for consideration in the upcoming national defense authorization act 
and conferred with our Office of General Counsel regarding its status 
and potential impact.

Although not part of our reporting objectives, in order to meet the 
reporting requirements of the John Warner National Defense 
Authorization Act for Fiscal Year 2007 we provide data on personnel 
tempo trends in appendix I, and retention rates for enlisted 
occupational specialties that have experienced unusually high or low 
deployment rates in appendix II.

To develop personnel tempo trends, we analyzed fiscal year 2001 to 
fiscal year 2006 data from the DMDC Personnel Tempo (PERSTEMPO) 
database using statistical analysis software (SAS). We also obtained 
and analyzed fiscal year 2001 to fiscal year 2006 data from the DMDC 
end strength databases---the Active Duty Military Personnel Master File 
and the Reserve Components Common Personnel Data System. Using the 
PERSTEMPO and end strength data, we completed an analysis identifying 
the yearly end strength population, the population of deployed 
personnel, and the total number of cumulative days deployed. Because of 
known limitations in the PERSTEMPO database, we completed a comparative 
analysis with fiscal years 2001-2006 data from the DMDC Contingency 
Tracking System (CTS) Deployment and Activation File datasets. Using 
the CTS and end strength data, we completed an analysis identifying the 
yearly end strength population, the population of deployed personnel, 
and the total number of cumulative days deployed. From these three 
figures, we calculated the yearly personnel tempo average for each 
database---PERSTEMPO, CTS Deployment File, and CTS Activation File. We 
compared the resulting calculations as well as the corresponding trends 
as one measure of the reliability of the PERSTEMPO data. To assess the 
reliability of the PERSTEMPO data, we spoke with knowledgeable DMDC 
officials about data quality issues and the internal controls on the 
system, and we reviewed prior GAO work on the PERSTEMPO data and 
system. Based on this information, we determined the PERSTEMPO data 
were not reliable indices of personnel tempo trends. We did not use 
PERSTEMPO data to support findings or recommendations and present 
PERSTEMPO data only in appendix I, with the associated data reliability 
caveats, because of the known limitations in the reliability of the 
data. These data are included in appendix I because of the legislative 
mandate to provide personnel tempo trends, and despite the known 
limitations, they are the only data DOD maintains on personnel tempo 
for all global war on terrorism contingencies.

To determine retention rates for enlisted occupational specialties that 
have experienced unusually high or low deployment rates, we obtained 
fiscal year 2001 to fiscal year 2006 data from the DMDC CTS Deployment 
File, and active and reserve end strength files. Using these data, we 
calculated deployment statistics and defined the occupational 
specialties experiencing unusually high or low deployment rates based 
on quartile analysis. The identified occupational specialties were then 
transmitted to DMDC, and DMDC provided retention or attrition data for 
each occupation specialty for the fiscal years 2001-2006 period. To 
assess the reliability of CTS and end strength data, we spoke with DMDC 
officials who were knowledgeable of the data and systems, reviewed data 
system documentation, obtained written responses to questions regarding 
the internal controls on the systems, reviewed previous GAO work on the 
data and systems, and performed electronic data tests for anomalous and 
missing data. We determined the CTS and end strength data we used were 
reliable for the purposes of this report. To ensure the accuracy of 
GAO's analysis, all programs were verified for logic and accuracy by an 
independent reviewer.

We discussed our methodology for calculating and tabulating these data 
with officials from the (1) Under Secretary of Defense for Personnel 
and Readiness, Arlington, Virginia, including Military Personnel 
Policy, Arlington, Virginia and Defense Manpower Data Center (DMDC 
West), Seaside, California; (2) Assistant Secretary of Defense, Reserve 
Affairs, Arlington, Virginia; (3) Department of the Army, Human 
Resources Command, Alexandria, Virginia (Active); (4) National Guard 
Bureau, G-1, Selected Reserve Branch, Arlington, Virginia; and (5) 
United States Marine Corps, Manpower Plans and Policy Division, 
Quantico Marine Corps Base, Virginia. The following list contains 
details about the methods and assumption we used in analyzing DMDC data 
files:

1. End-of-September End Strength files were used to represent the end 
strength for the preceding fiscal year for both active and reserve 
service members.

2. For the yearly analysis, the number of days activated/deployed 
includes both the day the activation or deployment started and the day 
it ended.

3. For activations or deployments that extend across fiscal years, the 
days for each year are counted through September 30 of that year and 
subsequent days are attributed to the following year.

4. Activations or deployments that began in fiscal years 2005-2006 and 
had "unknown" end dates were included in the yearly analysis because 
the missing dates could indicate ongoing activations or deployments.

5. Activations or deployments that began in fiscal years 2001-2004 and 
had "unknown" end dates were excluded from the yearly analysis based on 
the assumption that activations or deployments do not typically extend 
for 2 years and the dates more likely represent "missing" data.

6. The MOS analysis was based on Primary Service Military Occupational 
Specialty (PMOS) codes.

7. In instances of data anomalies, we communicated with DMDC and 
incorporated their suggestions for resolution.

8. The data we received from DMDC contained no PERSTEMPO events that 
began in fiscal year 2001.

Because there are a variety of factors affecting retention for which we 
were not able to account in our analysis, we did not attempt to make 
any conclusions concerning the relationship between deployment and 
retention or attrition rates. However, we collected and reviewed 
information about some of these other factors that affect retention.

We conducted our work from June 2006 to May 2007 in accordance with 
generally accepted government auditing standards.

Dear Ms. Pickup:

This is the Department of Defense (DoD) response to the GAO draft 
report, "Military Personnel: DoD Lacks Reliable Personnel Tempo Data 
and Needs Quality Controls to Improve Data Accuracy," dated June 1, 
2007 (GAO Code 350868).

GAO DRAFT REPORT — DATED JUNE 1, 2007
GAO CODE 350868/GAO-07-780:

"Military Personnel: DoD Lacks Reliable Personnel Tempo Data and Needs 
Quality Controls to Improve Data Accuracy":

Department Of Defense Comments To The Recommendations:

Recommendation 1: The GAO recommended that the Secretary of Defense 
direct the Undersecretary of Defense for Personnel and Readiness to 
provide guidance, which directs the Army and Marine Corps to develop 
quality control procedures for validating the accuracy of the personnel 
tempo data they collect and report to DMDC, whether under the existing 
personnel tempo definition or under any revised definitions that 
Congress may approve.

Dod Response: The Department concurs with the recommendation.

Department Of Defense Comments: 
Technical Corrections:

1. 1st Page, 1st Paragraph, 1st Sentence:
Recommendation: Rewrite 1st sentence as follows: "Congress has 
repeatedly expressed concerns about the pace of military operations; 
and since 2001, approximately 931,000 US. Army and Marine Corps service 
members, have deployed for military operations abroad in support of the 
Global War on Terrorism, including approximately 312,000 Guard and 
Reserve members."
Rationale: Accuracy in the reported number deployed.
[See comment 1]

2. 1st Page, 1st Paragraph:
Recommendation: Rewrite the 1st paragraph as follows: "Congress has 
repeatedly expressed concerns about the pace of military operations. 
Utilizing the Partial Mobilization Authority (10 US. Code 12302) as 
authorized by Presidential Executive Order 13223 on September 14, 2001, 
the US. Army and Marine Corps have deployed approximately 931,000 
members, of which approximately 312,000 have been Guard and Reserve, 
for military operations abroad in support of the Global War on 
Terrorism. Prior to this authorization, and as a result of 
Congressional concerns the Department of Defense was required to report 
personnel tempo to Congress as mandated in the National Defense 
Authorization Act for Fiscal Year 2000 (FY 2000 NDAA). Title 37 of the 
U.S. Code was amended with the addition of a section requiring the 
secretaries of the military services to pay high-deployment 
compensation payments to service members for lengthy or numerous 
deployments in excess of set limits. A section was added to Title 10 of 
the U.S. Code requiring management of deployments of service members in 
danger of exceeding high-deployment days thresholds! Sections were 
added to Title 10 of the US. Code requiring the Secretary of Defense to 
include personnel tempo information in his annual report to the
[See comment 2]

President and Congress and making the Under Secretary of Defense for 
Personnel and Readiness (OSD P&R) responsible for monitoring personnel 
tempo and establishing related standards and policies, subject to the 
authority, direction and control of the Secretary of Defense. 

Rationale: There are several disparate issues that are being addressed 
in the original paragraph as written. 1) Implication that the Congress 
has recently placed statutory limits on the numbers of reserve 
personnel that can be involuntarily called to active duty due to 
concern about the negative effects on individual service members and 
service readiness. The legislative authorities have been implemented 
over the last 60 years and have been modified as needed to address 
certain requirements and grant certain levels of authority. None of the 
involuntary recall legislative authorities have been modified as a 
result of current military operations in support of the Global War on 
Terror and 2) that personnel tempo issues are related to the time limit 
that an individual may be involuntarily activated. The third sentence, 
of the paragraph, implies that the time limits in the involuntary 
activation legislative authorities are related to the personnel tempo 
issues that were addressed in the National Defense Authorization Act of 
2000. Personnel tempo applies to both the Active and Reserve Components 
and addresses compensation, management and reporting of individuals 
that exceed certain deployment standards. Personnel tempo does not 
place any restrictions on the time duration that a reserve service 
member may be involuntarily activated.

3. 6th Page, "Results in Brief," 1st Paragraph, 4th Sentence:
Recommendation: Rewrite 1st sentence as follows: "For example, as of 
August 31, 2006, almost 421,000 reserve component personnel had been 
activated..."
Rationale: Accuracy in the reported number activated.
[See comment 3]

4. 10th" Page, "Reserve Mobilization," 1st para, 2nd Sentence:
Recommendation: Rewrite 2nd sentence as follows: "Most reserve 
component members who have been called to active duty for other than 
normal training since September 11, 2001, have been activated under one 
of the three legislative authorities listed in table 1."
Rationale: Service members are activated either in either a voluntary 
status or an involuntary status. Service member are not mobilized in a 
voluntary status.
[See comment 4]

5. 10th Page, "Reserve Mobilization," Table 1: Mobilization 
Authorities: 
Recommendation: Change table to reflect the following bold changes:
[See comment 5]

Table 1: Activation (in bold) Authorities:

Statute: 10 U.S.C. 12301 (d) "With members consent" (in bold)		
Type of	Activation: Voluntary;
Maximum Number of Ready Reserve	Members Who Can Be Activated (in 
bold)at Once: Unlimited;
Maximum	Length of Activation (in bold): Unlimited

Statute: 10 U.S.C. 12302 "Partial Mobilization";			
Type of	Activation: Involuntary;	
Maximum Number of Ready Reserve	Members Who Can Be Activated (in 
bold)at Once: 1,000,000	
Maximum	Length of Activation (in bold): 730 days/24 consecutive months;

Statute: 10 U.S.C. 12304: "Presidential Reserve Call-up";	
Type of	Activation: Involuntary;
Maximum Number of Ready Reserve	Members Who Can Be Activated (in 
bold)at Once: 200,000;
Maximum	Length of Activation (in bold): 365 days/12 consecutive months.

Rationale: 10 USC 12301(d) is not full mobilization but rather 
activation with the members consent (voluntary activation). The full 
mobilization authority is 12301(a), which is not a voluntary 
activation. The words activation and activated better reflect the 
status of an individual who has been called to active duty under one of 
the authorities listed above. 10 USC 1230 was an incomplete cite of the 
legislative section, it should be 12304.

6. 10th Page, "Reserve Mobilization," Table 1: Mobilization Authorities:
Recommendation: Annotate that 10 USC 12304 was used to support ongoing 
operations in Bosnia and Kosovo and has not been utilized since 2004.
Rationale: Provides clarity on the use of the three authorities. The 
table currently implies that all three legislative authorities have 
been utilized to support operations in support of Operations Enduring 
Freedom, Nobel Eagle and Iraqi Freedom.
[See comment 6]

7. 16th Page, 1st Paragraph, 1st Line:
Recommendation: Rewrite sentence as follows: "According to DOD data, 
almost 421,000 reserve component personnel were currently activated or 
had been previously activated as of August 31, 2006."
Rational: Accuracy in numbers reported.
[See comment 3]

8. 18th Page, "Mobilization policy Changes..." Last Paragraph, 1st 
Sentence:
Recommendation: Rewrite sentence as follows: "The new guidance 
specifies that future involuntary mobilizations will generally be 
limited to 12 months, with possible service exceptions for individual 
skill training required for deployment and post-mobilization leave, and 
other exceptions if approved by the Secretary of Defense."
Rationale: Pre-deployment training implies block unit training. The 
Secretary of Defense has stipulated that only individual skill 
training, i.e. military occupational skills, will be permitted.
[See comment 7]

9. 19th Page, Footnote 25 (and elsewhere it the report):
Recommendation: Rewrite last sentence as follows: "The secretaries of 
the military departments will be able to add other operational 
commitments discretionally."
Rational: Proper usage, the military has secretaries of the military 
departments not service secretaries.
[See comment 8]

10. 25th Conclusions," 1st Paragraph, 1" Line:
Recommendation: Change "1.5 million" to "931K"
Rationale: There have been approximately 931K Army and Marine Corps 
personnel that have deployed in support of the GWOT, not the 1.5 
million stated.
[See comment 1]

11. 30th Page, "Service retention and Attrition Tracking" last line on 
page:
Recommendation: Change to read "DoD tracks National Guard and Reserve 
attrition rates, which is defined as the number of service members who 
leave those components in a given year divided by the components' 
average strength as measured at the beginning of the fiscal year and at 
the end of that fiscal year."
Rationale: DoD does not track strength through the use of attrition, 
attrition is calculated as described above.
[See comment 9]

GAO Comments:

1. We revised the numbers as suggested to reflect additional data 
provided by DOD.

2. We disagree with DOD's assertion that several disparate issues are 
being addressed in the original paragraph as written and have not 
changed the report text in response to that assertion. The entire 
paragraph supports the initial clause of our topic sentence--"Congress 
has repeatedly expressed concerns about the pace of military 
operations." The sentences that follow the topic sentence all document 
ways that Congress has expressed its concern through legislation over 
the years. We note both the recent concerns that have been addressed 
through personnel tempo provisions and the long-standing concerns that 
were addressed through restrictions on the numbers of personnel who can 
be mobilized and the allowable lengths of mobilizations. However, in 
order to clarify the timing of the actions taken by Congress, we have 
made minor adjustments to the text. Furthermore, we note that, contrary 
to DOD's assertion that none of the involuntary recall authorities have 
been modified, in 2006, the Presidential Reserve Call-up authority 
found in 10 U.S.C. §12304 was amended[Footnote 33] with an extension of 
the number of days members could be called under the authority and the 
addition of criteria to be used to ensure fair treatment of reserve 
personnel before mobilizing them under this authority.

3. We revised the numbers as suggested to reflect additional data 
provided by DOD.

4. We have adjusted the text as suggested to provide additional 
clarification. Throughout the report we had used the term mobilization 
as it is commonly used to include personnel activations as well as the 
assembling of equipment. However, we acknowledge that activation is the 
more technically appropriate term and have thus changed "mobilization" 
to "activation" as suggested in this and other comments.

5. We have made the changes to the table as suggested.

6. We have added the suggested text as a footnote prior to the table.

7. We have adjusted the text as suggested to provide additional 
clarification.

8. We have adjusted the text as suggested.

9. We have adjusted the text as suggested.

FOOTNOTES

[1] Pub. L. No. 106-65, §923 (1999) defined personnel tempo as "the 
amount of time members of the armed forces are engaged in their 
official duties, at a location or under circumstances that make it 
infeasible for a member to spend off-duty time in the housing in which 
the member resides when on garrison duty at the member's permanent duty 
station." This is codified at 10 U.S.C. §487.

[2] Pub. L. No. 106-65, §586 (1999), codified at 37 U.S.C. §436 with 
subsequent amendments.

[3] Pub. L. No. 106-65, §586 (1999), codified at 10 U.S.C. §991 with 
subsequent amendments. Initially, this section required general or flag 
officer management of members who had been deployed 182 days or more 
out of the preceding 365 days, to ensure that they were not deployed 
for more than 220 days out of the preceding 365 without special 
approval. The National Defense Authorization Act for Fiscal Year 2004 
amended this section to require management of service members to ensure 
that the they were not deployed for more than 220 days out of the 
preceding 365 or more than 400 days out of the preceding 730 days 
without approval of the Secretary of Defense. The Secretary could 
delegate his approval authority to certain civilian officers and to a 
general or flag officer in that member's chain of command.

2004 NDAA to allow a monthly allowance of up to $1,000 for service 
members who had been deployed for 191 or more consecutive days or 401 
or more days out of the preceding 730 days. The act created additional 
provisions for determining compensations eligibility for members of the 
reserve components on active duty.

Active Duty Military Personnel Records (May 2, 2001).

[21] A few minor or temporary restrictions prevented the whole force 
from being available. For example, personnel are temporarily not 
available until they complete their initial training and pregnant 
service members are not permitted to be involuntarily activated, though 
they may volunteer to be activated under 10 U.S.C. §12301(d).

[22] The data showed that more than 160,000 of these personnel were not 
available for mobilizations of 12 months or more. The remainder had 
been mobilized but still had between 12 and 23 months of availability 
before they would have reached the 24-cumulative-month limitation.

[23] 10 U.S.C. §12302.

[24] GAO-04-1031.

[25] The Selected Reserve includes individual mobilization augmentees 
who train regularly with active component units as well as members who 
train regularly with National Guard or Reserve units. Individual Ready 
Reserve members are service members who have completed the active duty 
or Selected Reserve portions of their military contracts but who have 
not reached the end of their military service obligation. Although they 
were previously trained during periods of active duty service they do 
not participate in regular training.

[26] The rotation goals in the memorandum and implementing guidance 
generally called for reserve component personnel to be involuntarily 
mobilized for no more than 1 year and then demobilized for 5 years, but 
the guidance allowed the services to implement the 1:5 ratio with tour 
and demobilization periods of less than 1 and 5 years based on 
Secretary of Defense-approved force generation models. Marine Corps 
deployments are typically 7 months rather than 1 year. Under the new 
policies, active component personnel are to be deployed for 1 year and 
then at home station for 2 years.

[27] Creditable deployment time will be based on participation in 
Operation Enduring Freedom (Afghanistan), Operation Iraqi Freedom, or 
time with theater units in nearby areas. The secretaries of the 
military departments will be able to add other operational commitments 
discretionally.

[28] Because the services were required to begin collecting data under 
10 U.S.C. §991 on October 1, 2000, and the initial per diem payment 
provision, 37 U.S.C. §436, required that service members be deployed 
for 250 days out of the previous 365 in order to be eligible for per 
diem payments, the first time service members would have been eligible 
to receive per diem payments was October 1, 2001. The payment provision 
was waived 7 days later, on October 8, 2001, and according to DOD 
officials, no payments were ever issued.

[29] Marine Corps inspection teams were focused primarily on financial 
inspections and personnel tempo was only a part of the inspections. The 
inspections were not comprehensive and covered only a portion of the 
Marine Corps.

[30] These data are tracked in DMDC's Contingency Tracking System.

[31] This proposal was part of the legislative package submitted for 
consideration as part of the Fiscal Year 2008 National Defense 
Authorization Bill.
