In the scene near the beginning of the movie were John Travolta is in the office of the general's daughter. He is getting up to leave you notice that he has 1sgt rank on. For those of you who don’t know it has the diamond in the middle. When he leaves she calls him back and he sticks his head back in. He now has Master Sgt. rank on. The diamond is gone. I have no clue how this could happen. He is only in the bdu’s for a bout 15 mins of the movie. You have to look quickly for this one but it is a big one.
