I've had that - once. Some jackass came out of basic and asked who the fuck I was when I asked him to do something. That's the only time I've yelled in anyone's face. Needless to say, he was my bitch for a good two years. Any crap detail I could find, he was on it. In the end he actually turned out to be an alright Soldier. I don't know what unit he's in now but I hope they've kept him in line.
