Squadron (aviation)
One such example are the air base defence units, which are squadrons (German, plural: Staffeln) formed into battalions.The ground based missile air defence units are also company- (in this case battery-)equivalent squadrons (staffeln).The Swedish Air Force adopted naval-like traditions in its formative years and for that historical reason calls its squadrons divisions (plural: divisioner).For example, the air base where the F 10 wing is stationed (in Ängelholm) is commonly referred to as F 10 even though it is the name of the tactical unit.Case in point is Uppsala-Ärna air base, an active military airport but since the tactical unit located there has been disbanded it is no longer referred to as F 16.During the infant years of combat aviation in World War I and specifically with the trench stalemate at the front military aircraft partially took over the reconnaissance role from the cavalry.In the Air Training Corps of the United Kingdom and many Commonwealth nations, a squadron is a group of cadets who parade regularly.Commanding officers (COs) of U.S. Navy flying squadrons other than FRS units will be assisted by an executive officer (XO) of the same rank who functions as a second-in-command and who will eventually "fleet up" and relieve the CO as the next CO.[15] In United States Marine Corps Aviation, in addition to flying units that are patterned in similar fashion to their U.S. Navy counterparts, the nomenclature "squadron" in the Marine Corps is also used to designate all battalion-equivalent, aviation support organizations.As the official civilian auxiliary of the U.S. Air Force, CAP follows the USAF organizational model.
