Read: Dong Xoai, Vietnam 1965 by Joe Kubert, 2010, 9781401221423.
Comic book story. This was returned by a guy at the library and I checked it out for myself. I generally don't like Kubert's illustrations. They always seem like unfinished sketches. They worked okay here though.
Story of an A-team in Vietnam. The are briefly posted at one camp and then assigned to Dong Xoai. Members are there as advisors and have trouble getting the regular and irregular Vietnamese units to train up to an effective force. Units and camp are under supported and under equipped. VC units attack in big numbers with mortars, recoilless rifles, even flamethrowers. Many Vietnamese flew the battle out of self-preservation or to evacuate their camp follower families.
A-team guys, and Seabees sent to construct defenses, fight back and hold together until evacuation. You know the battle was real, real, real, bad because two guys are awarded the Medal of Honor.
