What is the function of the Marine Wing Support Group (MWSG)?

• A. Provide air defense
• B. Provide support to the expeditionary air field and maintain the air field
• C. Provide airborne warning
• D. Provide aerial reconnaissance

Answer: (B)

The function of the Marine Wing Support Group is to provide the ground support that enables an expeditionary air field to operate and be sustained. This means everything needed to establish and maintain an airfield for the aircraft to land, take off, and be serviced, including airfield operations, engineering, transportation, supply, communications, and airfield services such as fueling and aircraft servicing. By coordinating these elements, the MWSG keeps the airfield functional in forward or austere locations, supporting the aviation combat elements of the MAGTF. The other options refer to capabilities handled by separate aviation units—air defense, airborne warning, and aerial reconnaissance—not the MWSG’s primary focus on ground support and airfield maintenance.
