Deliberate mistake: Throughout the entire movie, every time Charlie Sheen is not wearing his helmet, especially when he's out in the field in this tropical climate, his hair is always meticulously combed back, blow-dried and puffy. As a veteran, I know from personal experience that when you take your helmet off, especially in a climate like that, the reality is your hair will be messy, sweaty, pressed flat and most unattractive.
Platoon (1986)
1 deliberate mistake - chronological order
Directed by: Oliver Stone
Starring: Johnny Depp, Willem Dafoe, Forest Whitaker, Charlie Sheen, Tom Berenger, Keith David
Continuity mistake: After the napalm has been dropped and Charlie Sheen is blackened from the fire (and others are dead and burned), the vegetation is all still green and unscathed. Shouldn't that also be burned and destroyed from the napalm?

Trivia: The first time we see Willem Dafoe, he is holding his gun across his shoulders, as if he is holding a cross. Just a preview of his future.
