Corrected entry: While there is such thing as a "surface-to-air" Javelin missile of British design, the one being deployed in this film in the helicopter scene is the American made anti-tank weapon.
Corrected entry: At the end of the movie, Tatum turns a large 50 caliber weapon on the villain of the movie and fires it rapid fire repeatedly at him, killing him. A shot later from a distance, you see the villain just crumple over and fall down dead, barely any damage visible to him. Had this been real life, a high caliber weapon like that fired at such close range for such a long time would have torn his body to shreds, not left it intact for him to fall over. But this movie was rated PG-13, and showing the gore that would really have resulted in would have made it R.Quantom X
Corrected entry: After Foxx and Tatum go through the gate to the basement they leave the gate open. When the bad guys show up the gate is closed.
