Air force

An air force, also known in some countries as an air army or historically an army air corps , is in the broadest sense, the national military or armed service that primarily conducts aerial warfare.

The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation within a national air force. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft.

Many air forces are also responsible for operations of military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air-defense assets such as antiaircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems.

As an organization, the air forces have what "ground support" to support the pilots and aircrew. Similar to any civilian organization, there are supporting employees who assist and/or support other employees. Pilots cannot fly the aircraft without the assistance of other personnel such as civil engineers, loadmasters, fuels, and mechanics, and additional support-oriented career field.
