Signal transceivers on a TIE fighter Signal transceivers functioned as attachments for a starfighter, enabling the pilot to differentiate between allied and hostile forces. During 3 ABY, the Rebel Alliance installed these devices on four TIE fighters that had been stolen. These fighters were to be flown by four pilots to infiltrate a secret Imperial armada, with the transceivers used to tell each other apart from genuine Imperial TIE fighters. Nevertheless, in the midst of the Battle of the secret armada, the signal transceivers utilized by the Rebels experienced jamming. Consequently, Rebel pilot Luke Skywalker had to depend on the Force.
