World War II
After training in the US, moved to England, October–November 1942, for service with Eighth Air Force. Encountering bad weather while flying the North Atlantic route, the air echelon remained for about a month in Greenland, where it searched for missing aircraft and dropped supplies to downed crews.

After the air and ground echelons were united in Dec, the group began ferrying cargo in the British Isles and training with airborne troops and gliders. In May 1943 a "detachment" comprising almost all the group aircraft, aircrews, and most support personnel, deployed to North Africa to support Twelfth Air Force and other Mediterranean Theater of Operations organizations during the invasions of Sicily and Italy. Although the group did not participate in the airborne phase of the invasions, it did support those operations by transporting supplies in the theater.

In March 1944 the detachment returned to England and rejoined the group, which had been reassigned to Ninth Air Force in October 1943. Prepared for the invasion of the Continent, and dropped paratroops near Cherbourg early on 6 June 1944, earning a Distinguished Unit Citation (DUC) for its action in the Normandy invasion.

Dropped paratroops of the 82d Airborne Division on 17 September 1944 when the Allies launched the air attack on Holland; flew reinforcement missions on succeeding days, landing at Grave on 26 September to unload paratroops and supplies. Airlifted gasoline and other critical supplies to Antwerp and Liege during the Battle of the Bulge, December 1944 – January 1945.

Released British paratroops near Wesel during the airborne assault across the Rhine in March 1945. Following each airborne operation, the group resumed transport activities, hauling cargo and evacuating wounded personnel. Moved to France in April 1945.

Transported cargo and evacuated allied former prisoners of war until after V-E Day. Moved to Trinidad in May 1945 and transported troops returning to the US. Inactivated on 31 July 1945.

Cold War
Activated in 1947, the group was not manned or equipped, and inactivated again in 1948. Next activated in Japan in 1952, assigned to Far East Forces, for duty during the Korean War. Flew troop and cargo airlift and airdrop, leaflet drops, spray missions, air evacuation, search and rescue, and other aerial missions between Japan and Korea. Remained in the Far East after the war to fly transport missions and paratroop training flights. Flew missions in Japan, Korea, French Indo-China, and other points until December 1954. Inactivated in Japan on 18 January 1955.

Organized in South Vietnam in December 1962, replacing a provisional troop carrier group. Exercised control over USAF airlift resources in Vietnam, using attached squadrons until permanent squadrons were assigned in July 1963. Provided combat evaluation of YC-123 aircraft, February–April 1963. Exercised control of some CV-2 aircraft of US Army, July–December 1963 and of a CV-2 Royal Australian Air Force detachment, 1964–1966. Gained the Ranch Hand defoliation mission in July 1964. Replaced in March 1966 by the 315th Air Commando Wing.

Modern era
Activated at Charleston AFB, SC, in the Reserve in August 1992 to control the airlift operations of the 315th Airlift Wing. Flew contingency operation, humanitarian airlift missions, and exercises worldwide, 1992–. In 1993, the 315th was the first Air Force Reserve group to fly the C-17 Globemaster III. It took part in the first US-Russian joint military exercise in 1994.
