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.
