Headquarters and Headquarters Squadron

A Headquarters and Headquarters Squadron, abbreviated as HHS or HQHQSQDN, is the headquarters entity for a United States Marine Corps aviation facility.

A H&HS usually consists of the headquarters group (the station commanding general or officer), the squadron headquarters (commanding officer and his staff), public affairs and journalism, facilities planning & maintenance, a motor pool, air traffic control, meteorology, fuels, ordnance, other aviation support, Aircraft Rescue and Firefighting, a Provost Marshal, the Station Judge Advocate's Office, some sort of United States Navy medical facility, and Marine Corps Community Services, which usually host services like a post exchange, a commissary, gas stations, barber shops, library, movie theater, family services, Single Marine Program, and the like.^[1]

Most Marine Corps Operational Support Airlift (OSA) assets and aircraft are attached to the H&HS at an air station or base rather than using the standard squadron-group-wing command structure of most other Marine Corps aviation units. The primary military occupational specialty (MOS) of an OSA aviator is to manage airfield operations; flying OSA aircraft is strictly a secondary MOS.^[2]
