I've been meaning to mention the Frontline program of this name, which I saw last month and which is worth watching, especially if you're interested in or concerned about the psychic effect of war (PTSD, etc.) or "hidden" physical effects (TBI, e.g.) and how the U.S. military does or doesn't address these.
On a related note, I saw in the library today Nancy Sherman's new book The Untold War. Unfortunately I probably won't get a chance to read it, at least not any time soon.
P.S. See also here.
