Raid on Yirt - 4138 - Grek - 12 In 22 BBY , during the Separatist Crisis , the Corporate Alliance conducted a raid against a group of slicers on an asteroid named Yirt - 4138 - Grek - 12 . Upon learning of a secret slicer compound on the asteroid used to supply espionage agents who were stealing data from the Corporate Alliance , the corporation deployed its NR - N99 " Persuader " - class droid enforcers on the asteroid , and the droid tanks attacked the base . Following the attack , twenty - five slicers lay dead , and the base was annihilated . While some senators of the Galactic Republic believed the attack to be excessive , it nonetheless fell within legal boundaries . Prelude . During the Separatist Crisis in 22 BBY , a secret industrial espionage training center was located on a remote asteroid named Yirt - 4138 - Grek - 12 in the Corporate Alliance – controlled Fakir sector . The base was used to supply and train industrial espionage agents by building them starships and performing cybernetic surgeries on them , thus turning them into cyborgs . The base ' s operations were unauthorized by the Galactic Republic and , as such , were kept hidden by the parties who funded the facility . One of the base ' s agents was Denlace Sachoore , a twenty - four - year - old female who underwent surgery and came out with a cranium - implanted vessel drive . However , while working as a Corporate Alliance clerk , she was caught embezzling corporate data in the vessel drive and was questioned by Corporate Alliance expeditor s . Approximately a month later , the source of her training and surgery was traced to Yirt - 4138 - Grek - 12 , and the facility was discovered . Viewing the base as a potential threat to corporate revenues , the Corporate Alliance Directorate , led by Magistrate Passel Argente , decided in a 7 – 2 vote that instant eliminating actions were required . The raid . The Corporate Alliance sent transports containing NR - N99 " Persuader " - class droid enforcers to Yirt - 4138 - Grek - 12 , deploying them ten kilometers from the base . The droid tanks then proceeded to travel across the asteroid to the facility , where they breached the pressurized structure by using their laser and missile weaponry , and , as a result , twenty - five cybernetically - enhanced data thieves perished inside the base , which was completely destroyed . Aftermath . After the raid , Argente dispatched a holomessage to Corporate Alliance shareholders , in which he explained the details of the raiding mission and assured that the corporation would do everything it could to protect its business interests . The raid was later reported by HoloNet News . While the raid was perfectly legal , as it took place in Corporate Alliance space , a number of senators of the Galactic Senate , including Senator Gopple of Erigorm , objected to the attack , believing that the use of armored tank droids was too extreme . Behind the scenes . The raid was first mentioned in the in - universe " HoloNet News Vol . 531 48 " article " Corporate Alliance Attacks Slicer Compound " , part of the HoloNet News volume released on March 21 , 2002 . It was also mentioned in the entry for the Corporate Alliance in " The Official Star Wars Fact File 91 " .
