Talking about weapon recoil. I did managed to get a ticket to instruct cadets in full and small bore shooting and it was always good to see them do well.
One day caught a lad sticking his beret between the butt and his shoulder and told him that would make no difference if he pulled the rifle into his shoulder correctly. Nope he would not change his mind so rather than not let him shoot at all I let it stay. Lad fires his first round and screams blue murder afterwards. Checked his shoulder and there it was, a perfect imprint of his ATC cap badge in red skin. He chucked it way for his next pot.
