Continuity mistake: When Hambleton is rescued in the huey by Capt Clark, he drops his walking stick as he is hanging half in half out of the chopper and it falls out of the chopper. A few seconds later he has his walking stick as he is still trying to get in the chopper.
Other mistake: When Hambleton comes across the hooch where he gets attacked, upon spotting the hooch he racks the slide on his 1911, loading a round in to the chamber. When he is fighting the villager he racks the slide again to load his pistol.
Factual error: The two white jets they keep showing doing bombing runs, multiple times throughout this movie, are Air Force training jets, not combat aircraft.
Suggested correction: The aircraft are F-5 Tigers... They are absolutely combat aircraft.
I looked up the F-5 Tiger, and those planes do look similar to what I saw in the movie, but also very similar to films of training jets I've seen. Whatever those things were in the movie, they carried no bombs or missiles; they just flew over, and then stuff went off on the ground. https://www.military.com/equipment/f-5-tigershark.
OK - I think I found the answer - the F-5 Tiger is the combat aircraft and the F-5 Tigershark is the training version. They look almost the same but not quite.
