ARC troopers were trained to work autonomously, often behind enemy lines. They were usually given missions that were too difficult for regular troopers but sometimes they were given tasks that were better suited to one skilled person rather than a battalion. This particular ARC trooper is on a "personal" mission to locate a missing Jedi, a friend, who went vanished during an aid mission to the outer rim. Disguised as a bounty hunter he's managed to track down one of the individuals involved in his friends disappearance. With the generals lightsaber recovered he continues his search.
