United States Army Air Forces The United States Army Air Forces (USAAF or AAF) was the military aviation service of the United States of America during and immediately after World War II, successor to the United States Army Air Corps and the direct predecessor of the United States Air Force. The AAF was a component of the United States Army, which in 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Army Chief of Staff.
XV Corps (United States) The XV Corps of the US Army was initially constituted on 1 October 1933 as part of the Organized Reserves, and was activated on 15 February 1943 at Camp Beauregard, Louisiana. During the Second World War, XV Corps fought for 307 days in the European Theater of Operations, fighting from Normandy through France and southern Germany into Austria. The corps was commanded in combat by Major General Wade H. Haislip, initially as a subordinate unit to the Third U.S. Army and later as part of the Seventh U.S. Army.
