I once watched a tank commanded by a likely drunk Quebecois drive straight through a building with people inside while blasting Painkiller. Let me explain.

We couldn't go on joint patrols with the Canucks, because that meant the request had to go back to SOTF-S, up to CJSOTF-A, then over to ISAF, down through all of the Canadians' abbreviations and acronyms, then back up and down the other way, and CJSOTF didn't feel like bothering with all that so we never got joint patrols with the Canadian tankers.

Nobody said anything about QRF, though.

No shit, there I was, Panjwai district, 2011. Just a SIGINT nerd who was in way over his head. We had been pinned down for what seemed like forever in a drainage ditch by machine gun fire from a farmhouse, a sentence which describes a sizeable portion of my time in Afghanistan. It was how all the cool kids spent their afternoons in those days, very chic.

We called for ordnance, higher said no. Someone would have to get rid of the machine guns the old-fashioned way, but as one of us had already been hit we figured it'd best be someone they weren't already shooting at. So we called for QRF.
