An officer who previously served as enlisted personnel, theoretically possessing both leadership credentials and actual knowledge of how things work. Often viewed with suspicion by traditional officers and grudging respect by enlisted troops.
A professional soldier who fights for whoever signs the biggest check, with no particular loyalty to flags, causes, or patriotic speeches. These hired guns are motivated by cold, hard cash rather than national pride or ideological commitment. Think of them as military freelancers, except with significantly higher stakes than your average gig economy worker.
Military slang for millimeter, typically used when referring to caliber sizes of weapons or ammunition. Because saying 'fifty caliber' apparently requires too much oxygen during combat operations.
The alpha mast of a multi-masted sailing vessel; the tallest, most important pole that makes the ship actually sail instead of drift. It's basically the 'main character energy' of nautical architecture.
Either a tall support structure for sails (the nautical kind) or military-speak for non-judicial punishment where a commanding officer decides your fate without a courtroom. Both are equally terrifying.
The collective armed forces (army, navy, air force, marines) characterized by hierarchical structure, strategic doctrine, and operational discipline. It's organized chaos with better funding than most organizations.
A drill sergeant insult hurled at military recruits to motivate—or humiliate—them during boot camp. It's dehumanizing tough love designed to build character through psychological pressure and yelling.
