Private Joseph Mongo would’ve earned himself a Medal of Honor for falling on a grenade to keep it from killing his platoon mates, but the problem was the way he landed on it. It not only exploded out fragments, but also propelled his 17 silver fillings from his teeth throughout the company. So by throwing himself on the grenade caused even more carnage than if he had run for cover like everybody else was trying to. The fact that he was the idiot who pulled the pin and fumbled the grenade only adds to the consternation of the command structure.
