It replaced and absorbed the Aeronautical Division, U.S. Signal Corps, and was succeeded briefly by the Division of Military Aeronautics, and then by the Air Service, United States Army. The Aviation Section organized the first squadrons of the aviation arm and conducted the first military operations by the U.S. aviation on foreign soil.
