In the scene where Han and Lando are preparing to go to their separate ships before the battle of Endor, Han is trying to convince Lando to take the Millennium Falcon. Look at Lando's rank insignia and the leather strap across his chest. The camera switches between Lando and Han several times. Two or three of the times it switches to Lando, his rank badge and strap have switched sides too! The force is strong with this rank insignia badge.
