Marine Captain and classics major Nathaniel Fick is on C-SPAN2's BookTV now. He participated in both Afghanistan and Iraq. It's so different. He honestly talks about killing innocent Iraqis (and the way the command didn't want to lift a finger to help an injured Iraqi kid) and how the situation was _not_only_ starting to turn bad very quickly (by the time they got to Baghdad!) _but_also_ how the potential threats (the 20-40 year old men, as opposed to children and women) were _never_ particularly happy about the invasion, even in the South. The book he wrote is called "One Bullet Away"
