Continuity mistake: In all of the aircraft scenes, almost every time they showed his aircraft, he has different types of weapons on it.

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?

Factual error: Calendar date at the very beginning of the film (in the police station), shows the dates of Saturday 20th/Sunday 21st July 1983. However the 20th and 21st July 1983 fell on Wednesday and Thursday.

Continuity mistake: The film is supposed to take place in 1917, but several of the german soldiers our heroes encounter are armed with Bergman M18 sub-machineguns which didn't appear until a year later. To make things even worse all the guns comes with a magazine-type that didn't appear until the mid-thirties.
