What is the full name for the abbreviation MM?

Machinist's Mate is the full name for the abbreviation MM. In Navy ratings, the two-letter abbreviation comes from the rating name, so MM directly maps to Machinist's Mate. This rating focuses on operating and maintaining shipboard machinery and propulsion systems, such as engines and related equipment. The other options correspond to different ratings with their own abbreviations—Master-at-Arms (MA), Mass Communications Specialist (MC), and Logistics Specialist (LS)—so they don’t match MM.
