Plot hole: After the marines fire into the crowd and things die down, Jackson tells his men to stay down because of possible snipers. Yet he is standing upright the whole time. Not the best tactical move. One sniper and the mission loses its commanding officer.

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.
Colonel Hayes Hodges: I'll make you a deal. If you can tell me right now what the life expectancy was for second lieutenant dropped into a hot LZ in Vietnam in 1968, I'll tell you everything I remember about Ca Lu.
Major Mark Biggs: One week.
Colonel Hayes Hodges: Negative. Sixteen minutes. Sixteen fucking minutes. That's all I remember about Ca Lu.
