It's a gritty semi-documentary about an early Vietnam battle. I understand it was panned by movie reviewers at the time because the trend was not to portray Vietnam Soldiers as heroes. A commentary at the end states that the Soldiers didn't fight for their Country or the Flag but for each other. I find it to be vaguely insulting. I can't believe that the U.S. government would hire taxi drivers to deliver KIA notification during a battle and I expect it was added for drama. Anyway it's well worth watching.
