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.
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: airfield operations and communications (less air traffic control services), motor transport, engineer services (including bulk fuel and aircraft refueling), non-aviation supply and equipment maintenance, local security, medical services, and food services.
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.
