In some countries, the term "marshal" is used instead of "general" in the higher air force ranks. The four highest Royal Air Force ranks are marshal of the Royal Air Force, air chief marshal, air marshal and air vice marshal (although the first named, which has generally been suspended as a peacetime rank, is the only one which can properly be considered a marshal). The five-star rank of marshal of the Air Force is used by some Commonwealth and Middle Eastern air forces.
