The Military Airlift Command (MAC) is an inactive United States Air Force major command (MAJCOM) that was headquartered at Scott Air Force Base, Illinois. Established on 1 January 1966, MAC was the primary strategic airlift organization of the Air Force until 1974, when Air Force tactical airlift units in the Tactical Air Command (TAC) were merged into MAC to create a unified airlift organization. Inactivated on 1 June 1992, most of MAC’s personnel and equipment were reassigned to the new Air Mobility Command (AMC), with a smaller portion divided between U. Air Forces in Europe (USAFE), Pacific Air Forces (PACAF) and the newly created Air Education and Training Command (AETC). The heritage of MAC (and its predecessor organizations) was officially consolidated into AMC in 2016.
