Gunner's Mate (GM)
Gunner's Mates operate and maintain guided missile launching and torpedo launching/handling systems, rocket launchers, gun mounts and other ordnance systems and equipment. They train and supervise crews in the use of all types of ordnance equipment, from large caliber guns and missile systems to small arms. GMs stow, secure, requisition and reclassify explosives, and operate and maintain magazine flooding and sprinkler systems. They make mechanical, electrical and electronic casualty analysis using technical publications, blueprints, schematics and circuit diagrams; they repair, maintain, test and calibrate ordnance equipment.
GMs repair, maintain, test and calibrate micro processing equipment, and use and care for common hand tools, special tools and soldering equipment. They perform preventive and corrective maintenance on hydraulic and pneumatic systems and components associated with launching systems. GMs interpret color coding to determine values of capacitors and resistors, and tracing internal connections of power and audio transformers, chassis wiring and multi-conductor cables.
They operate and maintain night optical devices, and operate optical scanning and marking devices to label, identify and report explosives' utilization/expenditure. They serve as team member performing inspections and final closeout checks on weapons, and install and remove torpedo exploder mechanisms. Gunner's Mates should be capable of learning how to use test equipment and applicable hand tools to perform casualty analysis and arrive at solutions for problems in solid state, digital electronics, microprocessor logic, electrical, hydraulic and mechanical equipment. They should also have good memories, the ability to do detailed work, perform repetitive tasks and keep accurate records.
Due to the sensitive nature of some of the technical duties, the GM rating has special eligibility standards for reliability, integrity and trustworthiness. GMs must be U.S. citizens eligible for a security clearance. Adversely adjudicated drug abuse offenses will not receive waiver consideration. Normal hearing and color perception are required.
