The UJTL is a library of UJTs, which serve as a foundation for capabilities-based planning across the range of military operations. A UJT is an action assigned to provide a capability. The UJTL supports the DOD in joint capabilities-based planning, joint force development, readiness reporting, experimentation, joint training and education, and lessons learned. In accordance with (IAW) reference e, the authoritative UJTL DB will be used for development of a JMETL or agency mission-essential task list (AMETL) used in identifying required capabilities for mission success.
