Continuity mistake: When the Wolverines are attempting to get "the box", the Matt Eckert character is shooting through a window. When we see his point of view, there are blinds in the way of the camera, however every time it shows the actor, the blinds are open.
Continuity mistake: As the policeman, Tom Eckert, is on the megaphone and telling his boys that he loves them and to do what he would do, "to stop this piece of shit," when the camera is at his back, you can see the left shoulder area of the shirt pull in, like he is raising his left arm to point at Captain Cho. When we immediately switch views to the front, we see Tom starting to raise his arm to point, but he had already started the motion (as evidence from the shirt) in the previous shot.
Continuity mistake: Matt is firing a machine gun from a rooftop. At one point you can see there are about three rounds left in the feed. Immediately he fires a full burst for much longer than three or four rounds would allow.
Continuity mistake: As Jed and the others are fleeing from the Koreans, they drive through a park and back onto the road. When Jed get back onto the road, the drive shaft can be seen detached from the differential on his truck, but is in one piece after they crashed into the military Hummer. (00:15:10)
