British military slang for a soldier or serviceperson who has no formal legal training but confidently dispenses rules, regulations, and arguments — usually to challenge authority or exploit loopholes. The term is distinctly contemptuous, implying the person is argumentative, self-important, and more interested in scoring points than in practical outcomes. It has since broadened beyond military use to describe any workplace or social pest who fancies themselves an amateur expert in rules and rights, particularly in formal settings like union meetings or bureaucratic disputes.
Every unit has one barrack-room lawyer who can quote the regulations back at you chapter and verse but has never done an honest day's work.

Military slang for a soldier who considers themselves an authority on rules, regulations, and rights, typically someone who argues constantly about procedures and offers unsolicited legal opinions without actual authority. The term is dismissive and implies the person substitutes loud opinions for genuine expertise. Used across Commonwealth militaries and in British English more generally. The term carries no implication of actual legal expertise — quite the opposite, it implies someone who mistakes confidence for competence.
Every unit has one barrack-room lawyer who knows exactly which regulation you're violating.
