United States Air Force
The United States Air Force (USAF) is the aerial and space warfare service branch of the United States Armed Forces. It is one of the five branches of the United States Armed Forces, and one of the seven American uniformed services. Initially formed as a part of the United States Army on 1 August 1907, the USAF was established as a separate branch of the U.S. Armed Forces on 18 September 1947 with the passing of the National Security Act of 1947. It is the youngest branch of the U.S. Armed Forces, and the fourth in order of precedence. The USAF is the largest and most technologically advanced air force in the world. The Air Force articulates its core missions as air and space superiority, global integrated intelligence, surveillance, and reconnaissance, rapid global mobility, global strike, and command and control.
United States Air Force Security Forces
On 12 February 1942 the United States adopted the British air defense philosophy. The Army Chief of Staff, Gen. George C. Marshall, approved the allocation of 53,299 African-Americans to the Army Air Forces with the "stipulation that air base defense 'for the number of air bases found necessary' be organized and that 'Negro personnel' be used for this purpose as required." This order formed the Army Air Forces (AAF) air base security battalions in June 1942. Units were deployed throughout the European, Asian and African theaters and designed to defend against local ground attacks. These units were armed with rifles, machine guns and 37mm guns.
