The entire organization of the Army Air Forces is devoted to the basic function of assuring that the squadrons assigned to it are able successfully to discharge the missions assigned to them by the Commanding General of the Theater. In an Army Air Force are a number of different squadrons. The pilot of a single-place aircraft, and the airplane crew of a multi-place aircraft are the fundamental striking units. The aircraft pilots or crews are grouped into Flights, the basic combat unit, and the Flights in turn are assembled into the basic combat and administrative unit—the Squadron. The number of aircraft which form a Flight varies as does the number of aircraft which form a Squadron.
