Continuity mistake: When Tom Selleck rolls his plane upside down to dump the Afghan at several thousand feet altitude, you plainly see stationary tree tops at the bottom of the frame.
Continuity mistake: In the first scene of their "training" for the big mission, the text "Somewhere near Galveston, TX" shows up as a subtitle on the screen. As it does this, there is a nice, dark aerial shot of mountainous terrain which is supposedly to hide the troops from any outsiders. The problem is, there are no mountains within hundreds of miles of the Island of Galveston. The whole terrain in this area is so flat that you can practically see from one side of the island to the other. (00:21:45)
Visible crew/equipment: Near the beginning when Nick Nolte is in the back of the truck, the sun is behind the camera. You can see the shadow of the camera operator perfectly along with the camera's shadow.
