Definition

Military weapons, ammunition, and related equipment—basically anything designed to explode, propel, or otherwise ruin someone's day. Not to be confused with 'ordinance' (a local law), though both can blow up in your face if mishandled.

Example Usage

The ordnance technicians spent three hours safely disposing of the unexploded bombs found at the construction site.

Origin

From Middle French 'ordenance' meaning arrangement or military supplies

Fun Fact

Unexploded ordnance from WWI still kills people in Europe over a century later—the Iron Harvest—proving that old ordnance never dies, it just waits patiently underground.
