Other: When Kirby and the Sarge are in the helicopter during the big battle scene, when Kirby talks to Kowalski, you can see that Kirby's mouth is not matching what he says. Look closely because his hand blocks his mouth.

Mistakes
In this scene we see Muldoon giving a talk to the press. As he empties the ammo box on the desk where the press are seated we see John Wayne and another soldier in the background standing a meter apart. We then get a close up shot of Wayne and the other soldier and they are shoulder to shoulder. In the next long shot we see they are standing a meter apart. See more...
Trivia
Even though the US military had a big part in the production of this film they asked the producer (John Wayne) not to credit them because they thought the movie was so pro-military that it bordered on propaganda. See more...
Green Berets mistakes
Other: After one of Col. Kirby's soldiers has been killed he takes the dead soldier's M-16 and smashes it against a tree. Instead of a magazine the rifle has a plastic sound box, because the 'rifle' is really a toy made by Mattel.
Visible crew/equipment: During the scene where Bulldog's helicopter crashes, you can see the cable which was holding the helicopter before it dropped.
