Factual error: When the Delta Force lands on a beach, prior to their assault, their landing craft is lit up like a christmas tree. The commandos wear dark uniforms and have blackened their faces, but they also carry bright white ropes around their chests. Some of them are scuba-divers, wearing yellow oxygen-tanks. In short, in the real world they would have been spotted within minutes.
Continuity mistake: When Chuck and his compatriot are escaping from the terrorists in the Greek Orthodox Church van we see Chuck leaning out of the side of the van until the sliding door is hit with three shots in a near straight line, however, the next time we see the side door panel it is undamaged until subsequent shots which show a square grouping of four holes instead of a line of three.
