Yeah. "About Face" will never be on a booklist for military personnel, because Hackworth decided that Vietnam was bullshit, after three tours and attaining the rank of bird Colonel. What, why, how? Well, it's in the book. Before he had enough of it all, he was the guy that wrote the "[url=http://www.textfiles.com/survival/vietprmr.txt]Vietnam Primer[/url]" which was reading for troops being deployed to Vietnam.

But Hackworth was a battlefield commission from Korea that commanded troops in Vietnam and had a pretty good track record until he went on TV. Afterward, he became Newsweek's go-to man covering military matters. 

Also, David Halberstam's "The Best and the Brightest" for how presidential politics in the Kennedy and Johnson admins got the US into the war, as well as Neil Sheehan's "A Bright, Shining Lie" about how the relations were with the Vietnamese at the Colonel-and-up level.
