If a Marine lost a rifle, he paid for that sucker. I assume the Army is the same. You could be, and many were, court martialled (office hours) for pitted bores, etc. I think I posted a Muster Roll entry in the past for June 1918 where a 5th Regiment Marine (a cook) was recommended for a SCM for a pitted bore in his rifle. The cook won because he proved he was issued the rifle in that condition.
In case you didn't notice the time frame, this SCM took place while the battle for Belleau Wood raged on. Evidently SOS was doing inspections during the battle.
I was threatened with Office Hours (in 1972 at Camp Pendleton) for having hair too long after I got a haircut the day before (a burr cut). I went into the barracks and shaved my head, and that made him (GySgt) even more angry. I mopped floors all day. I used to watch guys shave with Right Guard and a lighter (blow torch). I saw a deflowered MsGySgt (then a Corporal) wash his privates with one of those old stiff bristle brushes we used to wash the floor. He used it like one polishes one's shoes with a back and forth motion.
You gotta love those Marines no matter how goofy they get.
Semper Fi,
