Corrected entry: In the scene just following the tragic village-burning episode the black soldiers were digging foxholes discussing their bad feelings concerning the killings. During the discussion they used the word "Holmes" when addressing each other. The phrase "Holmes" was coined in reference to the Boxer Larry Holmes who didn't win the heavy weight championship title until 1978, a good decade after the events in the movie were to take place.
Corrected entry: After the brief fight between Barnes and Chris, when Barnes has Chris pinned, he cuts him below the left eye with a knife.In the next scene Chris has no cut on his face or any marks.
Corrected entry: The scene is when The new guy (Charlie Sheen) is first initiated to the troops after reporting to his outfit. The rest of the platoon are sitting around doing weed and drinking Budweiser from a can.... you will notice the absence of pull tabs in which to open the cans of beer. The beer cans shown are opened ones like they use today. Back then Beer or any other beverages from a can during the 1960s to the early 1970s always had pull tabs, not like the ones shown.
Corrected entry: It seems the plane that drops napalm is an F16, but the F16 entered in action in 1978, not 1967.
Corrected entry: After the final battle at the end of the film, there is a scene where Francis who was in the hole with Taylor during the final battle, stabs himself in his right thigh so that he will be injured for the second time and sent out. In a scene shortly there after we see Francis loaded onto a helicopter and the bandage is on his left thigh and not the right one where he stabbed himself.
Corrected entry: In the scene where Chris Taylor is shooting at the feet of the Vietnamese man and shouting at him to dance, this action would have, at very least, injured the Vietnamese man severely. This is because of the fact that the M-16 rifle used an extremely high velocity bullet which, because of its high velocity and small size (I believe it was .223 caliber), broke up into fragments upon impact. In this case, fragments from the impact of the bullets into the ground would have flown up and caused a certain degree of injury.
Corrected entry: Some of the U.S. soldiers appear to be carrying M16 carbines (often referred to as the "Car 15"). The short M16s of the period were known as XM177s and had a noticeably shorter barrel. The CAR 15 version was not used until after the Vietnam period.
Corrected entry: At the end after Charlie sheen has shot Barnes an APC comes to them and administers help. When that APC starts to come out of the jungle you can see it is flying a flag. This flag is not the US flag however, it is the Nazi flag.
Corrected entry: After the scene when Sandy and Sal get blown-up at the camp Taylor and Mannie are sent to go out on point. In the initial scene when they are told to go out, if you look in Mannie's helmet at his pack of cigarettes they are Marlboro, in the next scene when he is on watch the cigarettes are Kool.
Corrected entry: Just after the scene when the soldiers burn a village and they are walking in a field along with some civilians, they are all noticeably left-handed (they carry their rifles with the trigger on their left side, pointing them to the right). The image is a reversed (flipped) shot.
Corrected entry: This movie is about US Army soldiers, but the actors wear the tan US Marine Corps web belts with frame buckles. Army web belts are black and the buckles are solid rather than frames.
