Around the time of 21 BBY, a terrorist attack struck Depot Bravo Five, a facility owned by the Grand Army of the Republic. The explosion resulted in the deaths of fifteen clone troopers. Captain Jaller Obrim led the Anti-Terrorism Unit of the Coruscant Security Force, who, along with the Forensics Unit, arrived to investigate. This incident triggered a mission involving both the GAR Special Operations Brigade and the CSF, aimed at dismantling the terrorist organization responsible.
