You don't know what weapons he could be wielding or how dangerous that guy could be, but you attack him with a fist to the stomach and a kick to the one of the shins.
Your kick has broken his leg and he has lost his footing. He falls onto the ground and stops himself from falling face-first by placing his arms in front of him. You think you have the advantage to the fight but then another man barges in through the door, and this one has a pistol aimed for your head. You can jump out of the way and make a run for it, run towards the person and steal the gun, or hold his buddy up as a shield. What do you do?
