On July 1, 1973, the 3-1-5 was again activated, this time in the Reserve as the 315th Military Airlift Wing, Associate. The 943rd Military Airlift Group, the first associate Wing in the southeastern United States when it was activated at Charleston Air Force Base in September 1969, was deactivated on this same date.
The 315th MAW inherited the personnel and equipment from the 943rd MAG as well as the three flying Squadrons, the 300th Military Airlift Squadron, Associate, the 701st MAS, A and the 707th MAS, A. Colonel Richard P. McFarland, the 943rd MAG Commander, became the new Commander of the 315 MAW.
Right away, the 315th MAW lived up to its rich heritage by garnering the Air Force Association's Outstanding Group Award in November of 1973. Also, in the fall of 1973, the 315th MAW took part in Operation Nickel Grass, a critical airlift resupply mission for the nation of Israel during the 1973 Arab-Israeli War.
