A person or device that breaks through, breaks open, or violates a boundary, wall, or agreement.
From 'breach' plus the agent suffix '-er,' indicating someone or something that performs the action of breaking.
Military breacher teams who blow through walls are modern descendants of siege engineers from medieval times—they've always been the specialists who break what others couldn't!
Agent noun '-er' historically defaulted to male (breacher = male rule-breaker). Parallel feminine forms rarely developed, embedding male as unmarked default.
Use 'breacher' gender-neutrally, or specify 'rule-breacher' or 'someone who breaches' when context is important.
["rule-breaker","one who breaches","breach agent"]
