The United States Marine Corps Aviation (USMCA) is the aircraft arm of the United States Marine Corps. Aviation units within the Marine Corps are assigned to support the Marine Air-Ground Task Force, as the aviation combat element, by providing six functions: assault support, antiair warfare, close air support, electronic warfare, control of aircraft and missiles, and aerial reconnaissance. The Corps operates rotary-wing, tiltrotor, and fixed-wing aircraft mainly to provide transport and close air support to its ground forces. Other aircraft types are also used in a variety of support and special-purpose roles. All Marine Corps 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.
