This is the moment Marines provide close air support against a simulated enemy with a powerful minigun at a training ground in California.

The close air support training took place at Marine Corps Air-Ground Combat Center Twentynine Palms in California, USA on 22nd April.

According to the video posted from Defence Visual Information Distribution Service Hub, the United States Marines with Marine Light Attack Squadron (HMLA-269) were flying, landing, piloting, and providing close air support by firing with the GAU-17 powerful minigun from UH-1Y Venom helicopters.

HMLA-269 and other assigned Marine Aircraft Group (MAG-29) squadrons trained to integrate and support various ground-based marine units as part of the Service Level Training Exercise (SLTE).

MAG-29 is a subordinate unit of the Second Marine Aircraft Wing, the aviation combat element of the Second Marine Expeditionary Force.

SLTE is a series of exercises designed to prepare Marines for operations around the globe by improving their skills to operate and conduct offensive and defensive combat operations.

The GAU-17 or M134 Minigun is an American NATO six-barrel rotary machine gun with a high rate of fire, from 2,000 to 6,000 rounds per minute.

The Bell UH-1Y Venom also called Super Huey is a twin-engine, medium-sized utility helicopter, built by Bell Helicopter under the H-1 upgrade program of the United States Marine Corps.
