In 150,082 CMT, Rex Do'org received a distress signal aboard Station Libra from one of the other Galactic Government outposts in the system that said that they had been attacked by an unidentified mobile suit. In response, Rex addressed the pilot of the mobile suit in a transmission that ordered them to disarm its combat systems and surrender into custody, or his men would open fire. Rex's subordinate Thaya informed him that the vessel was not complying, so Rex ordered his men to power up the Massive-Range Cannonry for a preemptive strike. Thaya then brought up a visual of the enemy ship on the main screen that revealed that it was a Bluemarines Corporation vessel. Rex gave the order to fire, so Station Libra's cannons destroyed the vessel in a blinding explosion. Rex expressed his concern that Bluemarines had gone rogue and ordered Thaya to report the incident to headquarters.
