Marine Wing Support Squadron (MWSS) function?

• A. Provides essential aviation ground support including motor transport, engineering services, refueling, weather services, NBC defense, and organizational maintenance; replaced MWSG; now organic to MAGs.
• B. Provides aerial refueling.
• C. Provides air defense.
• D. Operates runway lighting.

Answer: (A)

MWSS exists to provide the essential aviation ground support that keeps a Marine aircraft element able to operate from forward or austere airfields. That means motor transport to move people and materiel, engineering services to build and maintain facilities and runways, fueling and servicing of aircraft on the ground, weather services to forecast flight conditions, NBC defense readiness, and organizational maintenance for equipment and vehicles. This broad, hands-on support is what enables aircraft to fly, launch, and recover where needed. MWSS was created to replace the older MWSG concept and is now an integral, MAGTF-organic part of the aviation combat element, reinforcing the point that its role is ground support across multiple infrastructure and support functions. Aerial refueling, air defense, and runway lighting are not core MWSS functions: aerial refueling is done by dedicated refueling assets, air defense stems from air command/control assets, and runway lighting, while important, falls under specialized airfield operations and engineering rather than the full spectrum of aviation ground support MWSS provides.
