Hey, I'll never be fighting in a shooting way, and people are right, you can't really get it if you never did it.
However, I just got around to reading Chasing Ghosts by Paul Rieckhoff. This is real thing, fighting in the ugliest of situations, dealing not only with the enemy but bad officers and an Administration which doesn't want to support the troops. I really recommend the book, it's the closest any of us will get to the reality of war.
Back home, Paul's the guy behind the Iraq and Afghanistan Veterans of America, the deal is they need our help to give them a break. They're still getting screwed by the Administration.
