Sergeant Major Basil Plumley: Seen the new rifles too, the M-16.
Lt. Colonel Hal Moore: That's supposed to be a pretty good weapon.
Sergeant Major Basil Plumley: Ahh, lotsa plastic. Feels like a BB gun to me. Believe I'm gonna stick with my pistol.
Lt. Colonel Hal Moore: Think we're gonna get close enough to the enemy to use that?
Sergeant Major Basil Plumley: What do you think, sir?
Factual error: Just after Lyndon Johnson announces that the air mobile units will be sent to Vietnam (1965), a dance/party scene has everybody dancing and singing 'Hold On I'm Comin' by Sam and Dave. It was a hit, but not in 1965. It was a mid/late 1966 hit, almost a year after that party. The Ia Drang Valley battle took place in November, 1965, before that song was recorded.
