U.S. Navy Enlisted Rating Insignia for HanDBase - This is the most current list of U.S. Enlisted Navy Rating Insignia. The database includes the abbreviated rate (i.e. OS, BM, GM, IS, MS), full name of rate, a brief description of the duties performed, and an image of the rating insignia. If I am missing any that exist in today's Navy e-mail me with the rating and info about the rating. Thanks.
