Corrected entry: In the scene in when Sgt. Joker, Animal Mother and the other Marines are outside in the ruins at twilight time getting ready for the final assault on the sniper, you can see their breath in the cold night air when the speak. Obviously this scene was filmed in a cooler climate, as this would not happen in Vietnam.

Correction: You don't always have to be in cold air to see someone's breath. If the humidity conditions are right you can see someone's breathe when it is very warm.
