occupational rating of gunner's mate (GM) is a designation given by the Bureau of Naval Personnel (BUPERS) to enlisted sailors who either satisfactorily complete initial Gunner's Mate "A" school training, or who "strike" for the rating by showing competence in the field of ordnance. When "striking" one is not required to be a seaman, but must belong to one of three undesignated rates: Fireman (FN), Seaman (SN), or Airman (AN). (Striking is no longer authorized in the USCG) It is also possible to cross rate to Gunner's Mate. Cross rating refers to the act of an enlisted sailor "crossing" from their current rating to another rating of their choice, provided their ASVAB scores are high enough and there are open slots for the rate. The Gunner's Mate "A" school is held at Naval Training Center Great Lakes, Illinois and Yorktown, VA for the USCG. In its early years, the school was very hands-on, but it is now primarily conducted through technical educational tools, such as self-study computer-based training (CBT). Training focuses on the operation, maintenance, and troubleshooting of naval guns, missile launchers and torpedoes as well as a strong emphasis on basic

approved the merger of the gunner's mate (GM) and torpedoman's mate (TM) ratings into the GM rating. The move was made to leverage the strengths, knowledge, skills and abilities found in the two ratings to meet existing and future strategic mission needs. “The training sailors receive after basic training for their ratings on an apprentice level has been the same for both gunner's and torpedomen's mates,” said Senior Chief Torpedoman's Mate, Sherry Secrease of the Navy Personnel Command. “This makes the merger easier to accomplish.”Torpedoman's Mate and Gunner's Mate Ratings Merge
