After Austin and Emmett are picked up in the Jeep by the two Russian agents and stop in the desert, Austin discovers that they are not their legitimate contacts by the digital LCD wristwatch one of the agents is wearing. Austin tells Emmett that the agent is wearing "a Russian copy of a 1969 Timex digital". Timex was not producing an LCD digital watch in 1969. In fact, nobody was. Digital LCD watches were not introduced until 1972, and Timex did not produce one for many years after that.
When Fitz-Hume throws the live grenade back into its box and the Russians notice, two seconds before they scream you can hear a faint leading echo of that scream. This is due to use of spooled analog magnetic tape when magnetic state on one layer of tape in the spool influences the state of another. It is most noticeable after long silences like this scene. This flaw survives uncorrected even to HD versions shown on cable.
During the examination scene, in long shots the monitor's name is written on the blackboard under the heading "Monitor" (Mr. Walters). In close-ups, particularly when the monitor is seated at the desk, his name is missing and the space under "Monitor" is blank.
The gold-bordered, blue ribbon which Generals Sline and Miegs wear on their right side is the Presidential Unit Citation. While it is correct for U.S. Army personnel, such as General Miegs, to wear the Presidential Unit Citation above the name tag, U.S. Air Force personnel, like General Sline, actually wear the ribbon on their left side, along with all other ribbons and devices.
At the end of the movie the recalled ICBM explodes at 3000 Zulu time. Zulu time is the same as Universal Coordinated Time (UTC) and operates on a 24-hour clock. In a 24-hour clock the day runs from midnight to midnight and is divided into 24 hours, indicated by the hours passed since midnight, from 0 to 23 (e.g. 1600 hours is 4:00 P.M). 3000 hours is an impossible time in a 24-hour day.
During the "negotiation" scene all Russians are shown as awarded two times Golden Star of the Hero of the Soviet Union which is a highest Soviet award. Assuming they all where awarded by one for "saving the world" it's unlikely to believe they all committed another deed of the same scale before.
During the ambulance chase scene, an Afghani jumps from a horse to the back of the ambulance. An Afghani rolls from the back of the ambulance to give the audience the impression that he didn't make the jump. But if you look closely, you can see the first Afghani's headdress.
The text in Cyrillic above the launcher monitor is a nonsense. In fact it's just a chaotic mix of Russian letters. Text on the screen is, however, in correct Russian, but related to ship navigation and not to missile control.
At the beginning, the secret courier holding the satellite photos walks up to a building, where the exterior windows do not match the interior windows. After he is inside, we can see the windows are spaced farther apart.
The nighttime scene where the Tadzhik Highway Patrol stand in front of their patrol car with its headlights on shows the patrolmen blocking the lights somewhat. When the camera goes to Emmett and Austin, they appear fully lit, as if the patrolmen were not in the way of the headlights.
Scrambler by the rocket launcher gives message in Russian presumably automatically translated since originally sent from US military base most probably in English and is translated back in English by Austin absolutely incorrectly. The original text says "... no vacations for personnel until further notice..." and other similar things but there's no word about number sequence or instructions on how to handle the launcher control.
The scene after the checkpoint cabin blows up from grenades. Dan grabs a horse and they ride off together with the horse that had a white spot on its forehead and is a light brown color. The next scene they are walking with a different horse that has a long white strip on its face and is darker.
