get the door shut. >> now there are five men trapped in the space of roughly the size of a closet. so here your, these five soldiers in a humvee. can you leave? >> no. and we all knew that sooner or later, the firepower is going to breach. >> a rocket-propelled grenade hits nearby. it disabled the humvee's big gun and seriously wounds the men inside. >> it just sounded like a truck hitting another truck, just loud and metallic. and i remember feeling the impact on the side of my face like somebody slapping me as hard as they could. i didn't know if i lost consciousness, but i definitely was stunned to the point where i forgot where i was. once my eyes were open and i saw what was going on, it was like, holy crap, i'm alive, i'm still in.
