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.
