The United States Air Force Reserve (USAFR, AFR, or AFRES) is one of the United States Air Force's (USAF) two air reserve components, alongside the Air National Guard (ANG). The USAFR and ANG constitute the USAF's contribution to the reserve components of the United States Armed Forces. The USAFR represents the federal contribution to the reserve components while the ANG represents the states', certain territories', and the District of Columbia's contribution to the reserve components as the "air militia" of these entities.
The USAFR is overseen by the Air Force Reserve Command (AFRC), a major command (MAJCOM) of the United States Air Force, with its headquarters at Robins Air Force Base, Georgia. AFRC also plays an integral role in the day-to-day Air Force mission and is not strictly a force held in reserve for possible war or contingency operations. AFRC also supports the United States Space Force through the 310th Space Wing, pending the creation of a space reserve component. The "Chief of the Air Force Reserve" is, ex officio, the commanding officer of the AFRC and is typically a lieutenant general (a three-star general officer) and reports directly to the chief of staff of the Air Force.
