Exactly my point. Anyone would take a free ticket out of the combat zone. They aren't there to help defend America by their choice. They were originally there for the reasons you said you were, and they stayed there and followed orders instead of going to jail.
If they were there for a sense of duty and country, as herdman claimed, they wouldn't gladly take a free ticket out of that combat zone.
True. I guess my question is, do you think it takes more courage to do what Bruce did or what these injured combat veterans had to do?
