The depiction of Joe Galloway was a pc abomination. The film shows a disgust for his M-16 which was the reverse of the truth. The reporter travelled with his own personal M-16. He's shown in the February 2002 Proceedings with his Swedish K submachinegun at Danang in August 1965.
The film is generally accurate with the exception of the final attack and subsequent NV command post being moved.
Ironically the same month November 1965 LBJ lost the war at a fifteen-minute conference at the White House, cursing at the joint chiefs for their request for permission to bomb Hanoi and mine Haiphong. The meeting is described by the Marine officer present as aide to the chiefs in "The Day It Became the Longest War" May 1996 Proceedings.
LBJ's sanitation of target lists gave rise to Flight of the Intruder pilots risking lives to bomb "truck parks" which were valueless jungle.
