Factual error: During a shootout in a house of the white-dredded Haitian, there is a moment when Will Smith shoots the bad guy right in the eye. The camera enters the barrel of his Glock, and everybody can see the regular cylinder barrel with grooves. But barrels of Glocks always have polygonal rifling - the barrel channel seen is hexagonal, not cylindrical. (00:51:00)
Factual error: When the guys pop out of the tunnel and start shooting at the guards it shows bullets going into the pool making big splashes. At the angle they were shooting from the bullets would barely skim the water making very little splash if they even went into the pool at all. If these were true ex-Deltas they would most likely have a little better aim than just spewing a line of bullets until they hit someone. (02:07:40)
Factual error: When Mike and Marcus are fleeing from the bad guy they arrive from Havana to Guantanamo Bay in about two minutes, this is actually a 10 hour drive. (02:11:30 - 02:15:35)
Factual error: In the chase down the hill, in Cuba, there is an office with a sign "Alcaldia" (City Hall in Spanish). In Cuba the local government office is called "Poder Popular" (People's Power). (02:12:50)
Factual error: Near the end of the movie, right after they arrive at Guantanamo Bay and Smith fires both of his remaining bullets, Tapia puts him TMP SMG and you hear a hammer being cocked. The TMP has a internal striker much similar to Glock, so you wouldn't hear anything. (02:16:35)
Factual error: When Syd throws the pistol to detonate the landmine, nobody in the nearby vicinity seems to be injured except one 'bad guy' despite the fact that many modern anti-personnel mines project shrapnel to a radius of 30 meters. (02:17:35)
Factual error: In the final Cuba scene they fly from Miami to Cuba but nowhere near Guantanamo yet they drive just a few minutes out of town to the base. GTMO is 520 air miles from Miami and 520 from Havana.
