Mission to recover Imperial codes

In the year 2 BBY, Phoenix Cell dispatched Phoenix Leader Hera Syndulla and her Spectres crew on a mission to recover Imperial codes from the Imperial Security Bureau station on Killun 71 for the Alliance to Restore the Republic's attack on Lothal. The first battle of the Galactic Civil War saw Wedge Antilles, disguised as an Imperial pilot, fly a stolen Sentinel-class landing craft to Killun Station carrying the droids AP-5 and Chopper, who entered the base to steal the codes. AP-5, as a former Imperial droid, passed through the security and successfully acquired the codes without any problems. Chopper, however, was unlicensed, and had come to Grand Admiral Thrawn's attention as a rebel infiltrator after several of his past missions. Due to this, LT-319, a controller for the Imperial Information Office, detected the astromech droid from his listener ship and took Chopper over when he tried to steal the clearance codes from a port in the base. LT-319 decided not to alert Killun Station's personnel, as he wished to use Chopper to discover the location of Phoenix Squadron's base. AP-5 quickly noticed that something was wrong with Chopper, and attempted to inform Antilles on route to their rendezvous with the Ghost. However, the inventory droid's excessive pushiness, including following Wedge into the refresher, coupled with the controlled Chopper acting nice to Antilles, led the Lieutenant to assume that the droids were "playing some kind of spy game."

Upon their return to the Ghost, however, Syndulla quickly realized that something was wrong with her droid. LT-319 swiftly used Chopper to lure the Rebels into the freighter's cargo hold and trap them there, before installing a data spike to try and steal the base's coordinates from the ship's navicomputer. An attempt to blow the Spectres, AP-5 and Antilles into the vacuum of space was thwarted, and Syndulla sent AP-5 onto the Ghost hull to access some controls that would open the hatch to the cockpit. He accomplished this, but was witnessed by the controlled Chopper, who was sent outside to finish the protocol droid off, and knocked him off the Ghost hull, setting him adrift in space. Upon returning, Chopper was ambushed by the Spectres, and Syndulla used the spike to reverse the control feed, remotely blowing up LT-319's surveillance ship. Afterwards, they went back to retrieve AP-5. As the controller had not informed any other Imperial authorities of the theft, the Rebels' mission was successful.
