Maybe you ought to look up Bob Doles war record.He spent Years and multiple operations just to stay alive - and he's badly crippled -for life...
and his wounds weren't self-inflicted and needed more than a band aid - and he never turned tail and ran under fire, leaving men behind.
when your hero demanded to be sent home after his 3 "wounds" the commanders didn't argue -they were glad to see the back side of him - ah, wasn't that the backside he got one of his wounds in - the rice in the butt from a grenade he threw to close...
