Job Description
Boatswain’s Mates (BM) are Navy enlisted Sailors who conduct, direct, supervise, and train various operations and tasks, such as ship handling, boat operations, cargo handling, equipment maintenance, and administration.
People call them “Bos’n.” They work everywhere—ships, shore bases, wherever they’re needed. The job? Physical, outdoors, and nonstop.
It’s not all at sea either. There are shore assignments too.
And promotions? Plenty of chances, if you put in the work.
Fun Fact: Boatswain’s Mate is one of the oldest enlisted jobs in the U.S. Navy.
