Machinist's Mate (MM) Navy Rate Patch 1st-3rd Class
This is the appropriate rating patch for US Navy personnel with the rating of Machinist's Mate MM1, MM2, or MM3. Navy rates are only sold as first class rates and can be cut to second or third class.
Machinist's Mates (MM) ensure the continuous operation of engines, compressors, gears, refrigeration, and air-conditioning equipment aboard U.S. Navy ships and submarines. Sub-designations of the Machinist mate are Nuclear (MMN), Submarine Weapons (MMW), and Submarine Auxillary (MMA).
The U.S. Navy Enlisted Left Sleeve Rating Patch is Swiss-Loomed on midnight navy-blue wool serge material. By tradition the Petty Officer 1st Class patch must be hemmed to the proper rank for Petty Officer 2nd Class and Petty Officer 3rd Class.
