Factual error: As the 1st Battalion, 7th Cavalry lifts off from LZ X-Ray at the end of the battle, it can be seen that there are no more American troops left at the battlefield. However, by the time 1/7 CAV left LZ X-Ray, it had been relieved by two full battalions (2/7 CAV and 1/5 CAV). There were around 700 American soldiers occupying LZ X-Ray by the time 1/7 CAV lifted off.
Factual error: Throughout the battle, the artillery rounds impact far too soon after they have been called in. While the artillery supporting 1/7 CAV at Ia Drang did have some pre-planned targets, it is impossible for any gun crew to receive a fire mission, adjust the gun, and fire the round as quickly as depicted (i.e., in a matter of seconds).
Suggested correction: Several times you hear them say artillery at previously established coordinates...the guns were already dialled in to where they needed to be and all they had to do was shoot them.
Factual error: At the end of the movie, Maj. Crandall is depicted as flying a UH-1 gunship, and attacking the NVA positions. Maj. Bruce Crandall was the Company Commander of A Co., 229th Assault Helicopter Battalion, 1st Cavalry Division at the time of the Ia Drang battle. A/229th was a "lift" company, flying UH-1D "slicks" (troop carriers). There were no gunships assigned to that company. The gunships (UH-1Bs) supporting the battle were from D Co., 229th AHB. It's highly unlikely that Maj. Crandall would have commandeered an aircraft from the gunship company to attack the NVA.
Factual error: The two officers with the French Groupement Mobile 100 at the beginning are wearing Foreign Legion white képis. GM 100 was not a Foreign Legion unit. And even if it were, Foreign Legion officers wear black képis with red tops, not the white of the lower ranks.
Factual error: When Joe Galloway arrives at LZ X-Ray, he and LTC Moore greet each other as if they're meeting for the first time. However, Galloway had been on multiple patrols with Moore before, and the two were well acquainted by the time of the Ia Drang battle. Galloway also arrived at LZ X-Ray with his own M16, which had been given to him by another officer some time before. Ia Drang was not his first time firing a weapon in combat, and he was actually fairly used to it by that time (per his own account).
Factual error: Map in HQ shows Kampuchea. In 1965 it should have been Cambodia. It was Kampuchea from 1976.
Factual error: When LTC Moore is standing at the Jump Towers, you can see a flashing light in the distance to his right. This is likely a "modern day" MP vehicle since MP vehicles in the 1960s didn't have flashing lights, but rather rotating lights. (00:38:55)
