c. 32 BBY
Olun was apart of the Special Operations Brigade. He and his brother, Moz, were given specialized training by Null-class ARC trooper Jaing Skirata. Moz and Olun were later tasked to track down and execute rogue ARC troopers during the war. The troopers caught and executed ARC trooper Tavo, which would inspire Sull to desert from the Army. They would also be tasked to track down Sull and execute him. They tracked him to Gaftikar, unfortunately, the SO BDE had also sent A'den Skirata and Omega Squad to track him down as well. Omega captured him and brought him back and they sent Darman to investigate Sull's apartment. Moz and Olun ambushed him but were both killed immediately. Darman, feeling guilty about what he'd done, recited their names, a Mandalorian tradition that he would have to repeat for the rest of his life.
