Definition
Collecting spent ammunition casings from a firing range or training area. A tedious, mandatory task that somehow always falls to the lowest-ranking personnel present.
Example Usage
After qualification, we spent two hours policing brass in the rain before we could head back.
Origin
'Policing' as military cleanup terminology, 'brass' referring to shell casings
Fun Fact
Modern ranges sometimes use brass catchers or vacuum systems, but traditional hands-and-knees policing remains a rite of passage.
