At the end of the film, when Leah, Lando and Luke are attempting to escape Darth Vader's Star Destoyer, Vader asks the Admiril if he deactivated the hyper drive on the Millinium Falcon. During the wide angle shot, the admirl is wearing a rank insignia on the right side of his uniform that is made up of a row of red squares over a row of black squares. On the closeup of the admiril, the isignia changes to red squares over blue squares and, though I did not count, there seem to be less of them. Back to the wide angle, back to red over black. Shortly after this scene, when R2 fixes the hyperdrive and allows them to escape, we see a closup of the admirl, shocked and a bit concerned over his own fate. His isignia is back to red over blue but is now on the LEFT SIDE of his uniform!!!
