Missing in Action 2: The Beginning (1985)

Continuity mistake: At the onset of the movie, the chopper Braddock and his team are in is shot down over a lake and they have to bail. Each of the five men on board jumps and then their name is listed followed by a "Missing In Action" stamp on the screen. However, if you look closely in the chopper before they all get ready to bail, you will see another guy in the back with a hat on (and it is not Opelka, Franklin, or Nester) who wasn't supposed to be there. It looks a lot like one of the other Americans who was presumably killed in the firefight prior to the chopper arriving to pick up the remaining survivors, taking off and then being shot down.
