Senior airman

Senior airman (SrA) is the fourth enlisted rank in the United States Air Force, just above airman first class and below staff sergeant. It has a pay grade of E-4. Between its approval on 30 December 1975 (with implementation 1 June 1976) and 19 March 1991, senior airmen wore sleeve chevrons with blue center stars instead of silver to distinguish them from the non-commissioned officer rank of "sergeant", also a pay grade of E-4. The latter was abolished in 1991 and the blue center star was changed to white to conform to all enlisted rank chevrons.

The Air Force promotes an airman first class (A1C) to senior airman after 36 months time in service (TIS) and 20 months time in grade (TIG), or 28 months TIG, whichever occurs first. Outstanding airmen first class, limited to no more than 15 percent of the total, may be promoted to senior airmen six months early, in a competitive process called Below-the-Zone, which normally involves going before a competitive board. Senior airmen are expected to be technically proficient and begin to develop leadership skills, and may be expected to supervise an airman of lesser rank.

Air force

An air force, also known in some countries as an air army, is in the broadest sense, the national military organization that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy, or a marine corps. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions, and providing support to land and naval forces.

The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation either within a national air force or comprising several air components from allied nations. 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 the military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air defence assets such as anti-aircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. Some nations, principally Russia, the former Soviet Union and countries who modelled their militaries along Soviet lines, have an air defence force which is organizationally separate from their air force.

Staff sergeant

Staff Sergeant is a rank of non-commissioned officer used in the armed forces of several countries. It is also a police rank in some police services.

History of title

In origin certain senior sergeants were assigned to administrative, supervisory, or other specialist duties as part of the staff of a British army regiment. As such they held seniority over sergeants who were members of a battalion or company, and were paid correspondingly increased wages. Their seniority was indicated by a crown worn above the three sergeants' stripes on their uniform rank markings.

National variations

Australia

In the Australian Army and Cadets, the rank of staff sergeant is being phased out. It was usually held by the company quartermaster sergeant or the holders of other administrative roles. Staff sergeants are always addressed as "Staff Sergeant" or "Staff", never as "Sergeant" as it degrades their rank. "Chief" is another nickname though this is only used for the company chief clerk (in some instances the chief clerk role can be filled by another non-commissioned rank (but not warrant officer) and still be referred to as "Chief"). A staff sergeant ranks above sergeant and below warrant officer class 2.
