they were parked at the range. a nice line of dark glossy o.d. M60 tanks no one was supposed to be in the tanks. the range had not been declared clear for firing. Sgt Jurasin was standing near the front of the tank and heard the unmistakable sound of the breech block closing( for those of you who have never been in a tank the breech block is a massive hunk of metal that gets tripped with a two by four because you dont want any of your body parts near or in it when it slams shut) then the main gun fired. the muzzle blast broke both of the sergeants eardrums. off to Walter Reed Army hospital and lots of surgery allowed Sgt J to stay in the army. no thanks to the ass hole in the tank.
