Gunner's Mate

Description

The gunner’s mate (GM) is one of the oldest ratings in the Coast Guard. Formally established in 1797, GMs are responsible for the management of all ordnance. GMs work with everything from hand held firearms to machine guns to the shipboard MK75 gun mount. They are accountable for ammunition and pyrotechnics; operate, maintain, and repair small arms, mounts, weapon systems and related ordnance handling equipment. GMs also have the responsibility of training personnel in the proper handling and use of CG operated weapons. GMs receive intensive training in and develop skills in electronics, mechanical systems, hydraulics, and perform maintenance on all ordnance equipment: mechanical, electrical, and hydraulic.
