Tuning leopard/APC track by tapping end connectors with a hammer to hear the pitch.
"Go get some blinker fluid for the AVLBs"
"Get a can of squelch from the sigs guy, and don't let him tell you there's no such thing, they just hate giving it out."
I got caught with "get a BFA for Carl Gustav, and don't come back without one." I wandered around for 4 hours until a kindly gun plumber took pity on me and told me it didn't exist, so I went back to my room. My sect commander was ready to chew me a new one, but I told him what I was told to do, and that I didn't come back without it, so I was following orders. That was the beginning of my reputation as having a "BA".
