United States Marine Corps Aviation is the air component of the United States Marine Corps. Marine aviation has a very different mission and operation than its ground counterpart, and thus, has many of its own histories, traditions, terms, and procedures. Today, Marine aviation is task organized to support the Marine Air-Ground Task Force, as the aviation combat element, by providing six functions: assault support, antiair warfare, offensive air support, electronic warfare, control of aircraft and missiles, and aerial reconnaissance. The Corps operates both rotary-wing and fixed-wing aircraft mainly to provide transport and close air support to its ground forces. However, other aircraft types are also used in a variety of support and special-purpose roles. All Marine aviation falls under the influence of the Deputy Commandant for Aviation, whose job is to advise the Commandant of the Marine Corps in all matters relating to aviation, especially acquisition of new assets, conversions of current aircraft, maintenance, operation, and command.
