The first U.S. airborne operation was by the 509th Parachute Infantry Battalion in November 1942, as part of Operation Torch in North Africa. The U.S. 82nd and 101st Airborne Divisions saw the most action in the European Theater, with the former in Sicily and Italy in 1943, and both in Normandy and the Netherlands in 1944. The 517th Parachute Regimental Combat Team was the principal force in Operation Dragoon in Southern France. The 17th Airborne Division deployed to England in 1944 but did not see combat until the Battle of the Bulge in January 1945 where they, along with the 82nd and 101st Airborne Divisions were deployed as ground troops.
