Because of the inactivation of the installation's active duty KC-135 wing due to BRAC, the Air Force reassigned Grissom Air Force Base in 1994 to the Air Force Reserve which later became the Air Force Reserve Command (AFRC) in 1997. The base added Marine Corps Reserve units in 2001 and United States Navy Reserve units in 2002. In 2005, in an effort to consolidate Navy Reserve activities and units, the Navy Reserve transferred all its Grissom units to the Navy Operational Support Center at Heslar Naval Armory in Indianapolis, Indiana.
