Other mistake: The Digital logo on the laptop has been turned upside down especially for the film, since the logo would otherwise show upside down to the camera when the laptop is in use (most laptops are the same - the logo is the right way up to the user when the lid is shut).
Other mistake: When Kelly asks Sgt. Beach how much time is left to track the truck, he says "45 minutes" but if you look at the screen showing how much time is left it is nearly two hours.
Other mistake: Early in the film, LTC Tom Devoe takes a fax of the alleged missile train departure orders off the machine, and starts reading it as he walks to Dr. Julia Kelley's office, taking a moment or so to reach the office. After talking with Dr. Kelley for a moment, he still scans the list looking over her shoulder. After he walks away, Dr. Kelley reads aloud Kordurov as the second name on the list. Wouldn't Devoe have recognized the name as he scanned the list before he gave it to Dr. Kelley? (00:28:55 - 00:29:45)
