List of United States Marine Corps aviation support units

This is a list of United States Marine Corps aviation support squadrons, sorted by type.

Marine Wing Headquarters Squadrons
Marine Wing Headquarters Squadrons have the mission of providing command and administrative support for a Marine Aircraft Wing. The commanding general and his staff make up the bulk of this squadron.

Marine Aviation Logistics Squadrons
Marine Aviation Logistics Squadrons provide direct support to the Marine Aircraft Group. They perform supply and maintenance for aircraft and other Navy-funded equipment. A MALS must be capable of supporting multiple types of aircraft, as well as proving detachments for aviation combat elements.

Marine Air Control Squadrons
MACS are responsible for air traffic control (to include ground-based anti-aircraft weapons), early warning & intercept control, air surveillance, radar control, and airspace management.

Marine Air Support Squadrons
MASSs provide the Direct Air Support Center (DASC) which controls and coordinates tactical aircraft operations. They are responsible for the processing of immediate requests (e.g. Close Air Support, CASEVAC, and Assault Support), integrate and deconflict indirect fire support (e.g., artillery and mortars) with aviation assets, manage terminal control assets, and procedurally control aircraft.

Marine Tactical Air Command Squadrons
MTACS are 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.

Marine Wing Communication Squadrons
MWCSs provide all communication assets for the ACE, including radio, satellite, wire, and data technology.

Low Altitude Air Defense Battalions
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.

Marine Wing Support Squadrons
MWSSs perform all manner of ground support, including the creation and maintenance of expeditionary airfields and landing zones, engineer support, bulk fuels (including aircraft refueling), landing zone support, supply, maintenance of ground equipment, and providing local security for the ground assets of the MAW.

Combat Logistics Companies
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.
