Continuity: When Sandy and Sal are in the tent looking at all the papers in the ammo crate look at the guy smoking a cigar. It goes from 2 inches to a brand new one in at least 10-15 seconds.

Continuity: When Tubby Gardner is killed, they try to bandage him up, but he dies before anything can really be done. The bandage on his chest isn't fixed properly when he dies, when the shot goes and comes back to him lying dead, the bandage is fixed properly around his chest.

Continuity: 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.

Revealing: In the scene after the final battle, where Charlie Sheen is walking up on the crawling figure of Tom Berenger. In the shot of Tom Berenger crawling, you can see two electrical cords with white tape coming from Berenger's left leg as he is crawling, obviously used for the squibs when he is shot by Sheen.
