The Marine Wing Headquarters Squadron (MWHS) provides administrative and supply support for a Marine Aircraft Wing Headquarters (MAW HQ). The MAW HQ is a separate organization that directs and coordinates the operations of the MAW. The MAW HQ contains the wing commander (commanding general) and assistant wing commander, their personal staffs (aides-de-camp, drivers, etc.), and the chief of staff, the general staff divisions (G-1 through G-6), and the special staff departments (public affairs officer, wing inspector, staff judge advocate, wing medical officer, and wing chaplain). The wing commander fights the MAW from his operational command post located in the Tactical Air Command Center (TACC) maintained by the Marine Tactical Air Command Squadron (MTACS).
The Marine Aviation Logistics Squadron (MALS) provides direct support of intermediate aircraft maintenance, aviation supply, and aviation ordnance to the aircraft squadrons of a Marine Aircraft Group. A MALS is capable of supporting multiple types of aircraft, as well as providing detachments for the aviation combat elements of a MEB or MEU.
MACS are responsible for air traffic control and operate the Tactical Air Operations Center (TAOC), which directs antiair warfare (to include ground-based anti-aircraft weapons), early warning & intercept control, air surveillance, radar control, and airspace management.
MTACS provide the ACE commander with command and control functions necessary for the aviation mission. They establish a Tactical Air Command Center (TACC), which is the operational command post for the Marine Aircraft Wing, from which the Wing Commander and his battle staff command the tactical air battle, including tactical air support provided to ground forces (directed from the DASC in the MASS) and tactical air defense (directed by the TAOC in the MACS).
LAAD Battalions are responsible for close air defense protection of assets within the area of operation, with a secondary mission of local ground security for ACE elements. They are armed with surface to air weapons, as well as early warning and detection equipment. Currently, LAAD battalions are equipped with the FIM-92 Stinger, a man-portable surface-to-air missile, and the M2 .50 cal machinegun. The M1097 Avenger missile-equipped HMMWV has been retired by Marine forces.
The MWSS provides all essential aviation ground support to the MAG. This support includes: (1) airfield operations and (2) communications (less air traffic control services), (3) motor transport, engineer services (including (4) bulk fuel and (5) aircraft refueling), (6) non-aviation supply and (7) equipment maintenance, (8) local security, (9) medical services, and (10) food services.
A H&HS usually consists of the headquarters group (the station commanding general/commanding officer and staff), the squadron headquarters (commanding officer and staff), public affairs and journalism, facilities planning & maintenance, billeting and family housing offices, station motor pool, air traffic control, meteorology, fuels, ordnance, other aviation support, Aircraft Rescue and Firefighting, Provost Marshal section, station Judge Advocate's Office, station Chaplain, Navy medical facility, and Marine Corps Community Service, which usually hosts services such as a Marine Corps Exchamge (MCX) (i.e., post exchange), commissary, gas station, barber shop, dry cleaner, library, theater, golf couse, bowling center, fitness, recreation, hobby, craft and auto repair center(s), swimming pool, officer, SNCO, NCO clubs, family services, Single Marine Program, and other personal services vendors.
Combat Logistics Companies, while subordinate to a Marine Logistics Group provide intermediate ground logistics support to aviation units, to include supply and maintenance beyond organic capabilities. All Marine air stations not in proximity to a Marine Logistics Group have a tenant company.
