Corporal Carpenter jumped on a grenade and was gravely damaged. He should have died from the extensive injuries. His arm suffered thirty broken bones, shrapnel injuries to most of his body, he lost his right eye and most of his teeth. His jaw and right arm were shattered and he has undergone dozens of surgeries. While the doctors worked on him to save his life, he flatlined three times. He was in recovery for over three years and attributes his remarkable outcome to the incredible medical staff at Walter Reed Military Medical Center.
