Ratings should not be confused with "rates", which describe the Navy's and Coast Guard's enlisted pay-grades. Enlisted Navy and Coast Guardsmen are referred to by their rating and rate. For example, if someone's rate is Petty Officer 2nd Class and his rating is Boatswain's Mate; when combined, Boatswain's Mate 2nd Class (BM2) defines both. Although rates E-7 above are abbreviated similar to E-4 to E-6, the combined rating is listed before rate when completely spelled out. For instance, Master Chief Electronics Technician is abbreviated as ETCM. More examples are listed in the table below.
