Factual error: The scene depicting Lieutenant Kilgore throwing out death cards onto the dead VC is not accurate. Real death cards were printed in packs that contained just the ace of spades on each card and had messages written in Vietnamese on the other side. (00:27:55)

Factual error: Captain Willard narrates to himself, "I am beyond their timid lying, morality, and so I am beyond caring" as we see a downed helicopter burning in a tree. The main rotors are detached and would not be sitting on top of the helicopter had it actually crashed and not just been placed there. In an actual helicopter crash the rotors fly off. (01:22:10)

Factual error: The date on the top of Chef's letter from Eva says, "Sept" with the year conveniently whited out. If the letter was written in September of 1969 she couldn't have known about Manson who wasn't arrested until December 3, 1969. This also dates the movie as taking place sometime in 1970. (01:50:50)

Factual error: Captain Willard recalls back to lunch at General Corman's and we hear Harrison Ford's voice say as he points to a map, "Now he's crossed into Cambodia". The town he's pointing at (Ban Me Thout) and the one above it are in the Central Highlands in the middle of Vietnam and not crossover points anywhere near Cambodia. (01:18:20)
