Army Air Service and Air Corps Recruiting

The Air Service was the first form of the air force to have an independent organizational structure and identity. Although officers concurrently held rank in various branches, after May 1918 their branch designation in official correspondence while on aviation assignment changed from "ASSC" (Aviation Section, Signal Corps) to "AS, USA" (Air Service, United States Army). After July 1, 1920, its personnel became members of the Air Service branch, receiving new commissions. During the war its responsibilities and functions were split between two coordinate agencies, the Division of Military Aeronautics (DMA) and the Bureau of Aircraft Production (BAP), each reporting directly to the Secretary of War, creating a dual authority over military aviation that caused unity of command difficulties.

The seven-year history of the post-war Air Service was marked by a prolonged debate between adherents of airpower and the supporters of the traditional military services about the value of an independent Air Force. Airmen such as Brig. Gen. Billy Mitchell supported the concept. The Army's senior leadership from World War I, the United States Navy, and the majority of the nation's political leadership favored integration of all military aviation into the Army and Navy. Aided by a wave of pacifism following the war that drastically cut military budgets, opponents of an independent air force prevailed. The Air Service was renamed the Army Air Corps in 1926 as a compromise in the continuing struggle.
