Catalog listing, not a contract offer. Confirm with a recruiter.
Gunner's Mates maintain, repair, and operate the weapons aboard cutters and boats, from small arms and crew served machine guns to larger mounted systems. Most days are armory and maintenance work: inspection, cleaning, parts replacement, ammunition accountability, and records that track every weapon and round. You run range qualifications and train shipmates, which makes instruction a substantial part of the job rather than a side duty. Because Coast Guard cutters are boarding and law enforcement platforms under the Department of Homeland Security, these weapons exist to support drug interdiction, fisheries enforcement, and port security in and around American waters. Live firing is a small part of the year, and everything else is preparation for it.
You learn small arms and ordnance systems in depth, including mechanics, troubleshooting, headspace and timing, and higher level repairs most civilians never see. Ammunition handling, magazine safety, and explosives accountability are trained to an unforgiving standard. The rating makes you a firearms instructor in practice, teaching marksmanship, safety, and use of force fundamentals to crews. Hydraulic and electrical work on gun mounts adds a mechanical and systems dimension that widens the trade considerably. You also learn inventory control, serial number accountability, and the security procedures that govern weapons custody.
Absolute procedural discipline becomes a habit, because in ordnance a casual mistake is not a small error but a catastrophe. You develop a teaching instinct and the patience to correct a nervous shooter on the line without rattling them further. The role builds meticulous record keeping and a genuine comfort with accountability audits that make other people nervous. You learn to enforce a standard on your own peers, which is socially much harder than enforcing it on subordinates. Confidence around dangerous equipment grows steadily and without bravado, which is exactly how professionals in this field carry themselves.
Firearms expertise translates into law enforcement, federal agency armorer positions, firearms instruction, and the commercial gun industry. Municipal and state police, sheriff's departments, and federal agencies all value the weapons background alongside veterans' preference points. Manufacturers and defense contractors hire armorers, technical representatives, and range staff who already know the systems from the inside out. Range management and private firearms training are real businesses that veterans of this rating go on to run. The maintenance and inventory discipline also opens doors in logistics and supply roles that have nothing to do with weapons.

“After A-school I wanted an assignment on a 378-foot, high-endurance cutter, because they have the majority of systems that a gunner’s mate can work on and it would give me the experience I needed in my rating.”
“I never touched a weapon before I joined the Coast Guard.”
“I’ve been able to sail around the world with 120 plus of my closest friends and get paid.”

Your day opens in the armory conducting inventory of small arms and inspecting the deck-mounted weapons before the range or a boarding evolution. You clean and maintain the .50 cals and crew-served guns, run weapons drills, and issue and account for every firearm and round on the ship. When the security detail forms up, you brief the team, oversee the qualification range, and lock the armory down at day's end.
