The **815th Troop Carrier Squadron (TCS)** was an airlift unit of the United States Air Force, activated during World War II in 1943. Initially equipped with C-47 Skytrains, the squadron participated in airborne operations in the European Theater, including airdrops during D-Day and Operation Market Garden. After the war, the 815th supported occupation and transport missions before being inactivated in 1946. The unit was later reactivated during the Cold War era, flying C-119 Flying Boxcars and continuing its airlift and troop transport missions until its final inactivation.
