Continuity mistake: The soldiers takes off from the aircraft carrier in Boeing CH-46 helicopters. In the next scene they are flying towards the target and the helicopters are magically upgraded to the Boeing CH-47 model. The mistake is clearly seen when counting the landing gear on the two types. The CH-46 has a single front landing gear and the CH-47 has a double landing gear in the front.
Continuity mistake: Not only the CH-46s change into -47s, also the Bell 212/UH-1Ns (twin-engined) suddenly become Bell 205/UH-1Hs (single-engined).
Continuity mistake: Shortly after Samuel. L. Jackson speaks to the ambassador we see U.S. marines taking up positions on the rooftop, if you watch as the camera angle changes you can see the same bazooka carrying marine lie down in the same position he lay down in seconds earlier.
Continuity mistake: In the bar scene Samuel L. Jackson presents Tommy Lee Jones with a case with the Mameluke sword and Lee's medals in it. There is a Silver Star in the case, but Tommy Lee Jones is not wearing one. Tommy Lee Jones is wearing a Defense Distiguished Service Medal, which is not in the case. The medals do look very similar though.
