Huh? Don't know what you're talkin' about, Fred. Whatever we used, I was never very good at it.
Some of Uncle's more-senior minions would rather that you worked on your floor-polishing than the less-important stuff like weapons handling, marksmanship, map-reading, etc., right? I got some of that, too.
"My gear and weapons are clean and ready, Sergeant! Looking forward to the scheduled MOUT training today!"
"Yeah, but the floor's not shiny enough, Private. Get to work on it. We'll do MOUT some other time"
*edit*
That one was made up, this one isn't. Not exactly on point but in the same vein.
Midway through REFORGER in '82, on the third day of sitting on a hillside, most of us doing nothing but sitting while the NCOs played high-stakes Hearts, one of my squadmates complained to our buck sergeant squad leader, "I'm tired of just sittin' here, Sarge. When're we gonna do some training?" The response, to raucous laughter from the other NCOs, was, "How 'bout I make you you low crawl up and down this hill for a while? That's training."
