I think the sense of humor comes from the fact that in a airborne unit a infantry private you don't have any choices. You are expendable and the new guy. You volunteered to Be there and when you fuck up you get smoked.

Guys who get pissed off don't make it a lot of times. Those dudes stand out like a neon sign and they'll either change thru smoke sessions or remedial training or they quit and go to another unit or MOS.
