GMs are stationed throughout the Coast Guard, including Alaska and Hawaii. GMs typically work out of small armories afloat and ashore. GMs are stationed on large and small cutters. GMs work out of Area, District, Naval Engineering Support Units (NESU) and Weapons Augmentation Teams (WATs). GMs are sent to repair weapons as required from the NESUs and WATs. With the Coast Guard's broadening mission in Homeland Security, GMs are becoming involved with law enforcement and security at Marine Safety Offices (MSOs) and Marine Safety Security Teams (MSSTs).
Training for the GM rating is through formal instruction located in Yorktown, VA. A Gunner's Mate requires skills in electronics, mechanical systems, and hydraulics. GM 'A' School is currently 10 weeks of formal training. After 'A' School, most graduates immediately attend specific equipment/system specific 'C' Schools lasting from five days to 14 weeks. During a career of 20 years, a GM can expect to receive over two years of training in electronics, management, and leadership.
To be a GM, you should have an interest in all aspects of small arms weaponry (marksmanship training, function, and usage), and the mechanical operation and electronic function of weapons systems. An aptitude in mechanics, basic electrical theory, mathematics, and attention to detail will help.
