The DOD Reorganization Act of 1986 created the position of Vice Chairman of the Joint Chiefs of Staff, who performs such duties as the Chairman of the Joint Chiefs of Staff may prescribe. By law, he is the second ranking member of the Armed Forces and replaces the Chairman of the Joint Chiefs of Staff in his absence or disability. Though the Vice Chairman was not originally included as a member of the JCS, Section 911 of the National Defense Authorization Act of 1992 made him a full voting member of the JCS.
