Corrected entry: In the scene where Quaritch and Sully are talking for the first time, Quaritch checks his AMP suit and then climbs inside. A red "remove before operation" strap can be seen hanging off the front right side of the AMP suit, next to where the ammo belt comes out. As the two of them talk, the camera cuts back and forth a few times and the strap remains visible; in the last shot before Quaritch assumes control of the AMP suit and begins to walk, this strap has vanished.

Correction: There is a technician/mechanic working on the suit. He walks back and forth behind the suit before it starts up, so he must have removed the ribbon a few seconds before start-up.
