Many years ago while I was attending Air Police School We had a numb scull in our flight. One day he pointed his M1 at me, in front of our DI, Told him don't do that again but he thought I was funnin and did it again,going bang bang. I came acroos with a horizontal butt stroke and broke his cheek bone and jaw. The DI took him to the hospital an swore he fell down stairs. Nothing was ever said to me about it, and I never saw the guy again.
