Please get shot anywhere and tell me how easy it is for you to adjust your train of thought away from bodily danger and toward a target.

Then you paradoxically try to resume your task in the fight, until you realize your own bodily dysfunction. I started flailing and screaming as horribly as you could possibly imagine. I could hear people directing fire when someone saw me on the ground and started screaming like a banshee for a Corpsman. I could hear the corpsman call booming through the school house as I laid in the dirt writhing in agony and crazily pulling at the grass surrounding me, feebly attempting to displace the unmitigated sensation surging through me.
Then a warm pours over you, seeps through your body armor, pools down at your legs, and you can't even see it, because the one time you attempted to roll and have a gander is the first time you blacked out."
'McElhinney goes on to explain what he felt during the ambush, and how his fellow Marines, Afghan soldiers, and Navy Corpsmen fought back and kept him alive. A Stars and Stripes reporter on the patrol that day recalled him screaming "Oh God!" before falling face-down on a patch of grass, writhing in agony.'
Boy I bet this soldier was able to resist the pain long enough to get a quick shot in before blacking out. But in reality of the literal death match that is war all he had time to say was oh god before hitting the ground in an instant.
