During the final firefight, U.S. soldiers are seen using the M72 LAW antitank weapon. This weapon was phased out by the U.S. military in the early 1980s and was replaced by the M136 AT4 at the time of the film's release.
There are several instances of U.S. soldiers being killed by pistol rounds, even those wearing body armor. In actuality the Kevlar body armor currently worn by American military forces is more than capable of stopping pistol rounds of various calibers, even without the extra SAPI armor plates.
The supposed Humvees seen being driven by the U.S. soldiers are obvious souped-up civilian models with V-8 engine exhaust ports, most likely the Turkish equivalent of the U.S. model. The U.S. military standard Humvee does not have V-8 engines and are much smaller than depicted in this film.
In two scenes Turkish military officers are seen using Beretta M92F, 9mm handguns. Little known fact that only the Turkish police and police special response units employ this weapon. The military has Kirikkale 9mm-chambered pistols.
