Revealing mistake: During the montage when Torrance is talking about how they are going to have to practice longer and harder they show the squad attempting to do a Wolf Wall again. But you can tell that it is the same scene as the beginning, because all the people are wearing the same clothes and you can even see Carver, the girl who broke her leg, standing there next to Torrance.

Revealing mistake: When the team captain gets in the car accident, if you look at the damaged car right after it is hit by the truck you can clearly see the stunt driver wearing a black motorcycle helmet.
Revealing mistake: During the war flashback there is a newspaper photograph with Captain Junuh on the shoulders of Savannah's young men. When the camera zooms into his face you can see it's someone else's, only in close-up it switches to Matt Damon's. This is surprising because in all other newspaper pictures Matt Damon is nicely worked in. (00:06:15)
