Independent air forces

An independent air force is one which is a separate branch of a nation's armed forces and is, at least nominally, treated as a military service on par with that of older services like navies or armies. The British

The Canadian Air Force was formed at the end of World War I and was abolished and reorganized several times between 1918 and 1924.

Similarly, the Royal New Zealand Air Force was established in 1923 as the New Zealand Permanent Air Force, but did not become independent of the New Zealand Army until 1937. Other British-influenced countries also established independent air forces. For example, the Royal Egyptian Air Force was created in 1937, when Egyptian military aviation was separated from Army command. The Afghan Air Force was established on 22 August 1924, with support from the Soviet Union and Great Britain, but a civil war destroyed most of the planes and it wasn't reestablished until 1937, when King Mohammed Nadir Shah took power.

This proved very unpopular, and in 1975 Canadian aviation units were reorganized under a single organization ( Air Command) with a single commander. In 2011 the Canadian Forces Air Command reverted to its pre-1960s name, the Royal Canadian Air Force.

Organization

The organizational structures of air forces vary between nations: some air forces (such as the

, the

) are divided into commands, groups and squadrons; others (such as the Soviet Air Force) have an Army-style organizational structure. The modern Royal Canadian Air Force uses Air Division as the formation between wings and the entire air command. Like the RAF, Canadian wings consist of squadrons. In the case of China the Air Force headquarters consists of four departments: Command, Political, Logistic, and Equipment, which mirrors the four general departments of the People's Liberation Army. Below the headquarters, Military Region Air Forces (MRAF) direct divisions (Fighter, Attack, Bomber), which in turn direct regiments and squadrons.IISS Military Balance 2012, 233, 237

Infantry

Airborne infantry, such as the Royal Air Force Regiment, Royal Australian Air Force Airfield Defense Guards, RNZAF Security Forces, and the US Air Force Security Forces, are used primarily for ground-based defence of air bases and other air force facilities. They also have a number of other specialist roles, including Chemical, Biological, Radiological and Nuclear (CBRN) defense, offensive operations in defense of air force assets, and training other air force personnel in basic ground defence tactics.

Special forces
