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: 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.
