Husk was abused by his uber right wing drunk ass father. His dad always had to be number one. Most number best chick, toughest guy in the room. But his dad was not the top dog and often got taken down a notch. So he would freak out and take his rage out on young Husk. Beating into the lad the must be top dog mentality. So when humiliated and laughed at again and again each time Husk tries to take control of the unit and be the top alpha male he vows revenge. He buys a grenade off the black market. He throws it into your tent while you and your tent mates are sleeping off a ten hour surgery session with wounded soldiers. Your left leg with blown off at the knee and large deep chunks of your face are missing. Your torso is full of shrapnel and you cannot breathe. Your best friend Zapper John is blasted into debris and your not so liked tent mate Sigal Haterson is unharmed somehow.
Several unit personal witnessed Husk's attack. He is arrested and court marshaled. He is shot dead by a firing squad right here at the medical camp seven weeks later.
