Well, it is self satirical Irish humor. It is funny. However this is what Michael Moore uses too in his "documentaries" against corporations.
I have never met a grunt who said that he enjoyed being shot at, tip toeing thru minefields or looking at hundreds of corpses.
This guy hadn't evevn been thru boot camp and you guys are rippin him a new arsehole for being unaware of the lifestyle in combat. Fer chrissakes back off and see that he is denigrating himself not the Marines that he was with.
Remember your first time in combat? Did you want the fun to continue all day and night or were you so thankful when the bullets quit whizzing by your head? I sure was and I could have finished the rest of my service with never hearing another one or finding out that the jarhead in that other tent was dead. Back off!
