Purge Troopers were a variant of Stormtroopers that were tasked with hunting down Jedi Knights that had survived Order 66. Originally composed of Clone Troopers, they were eventually supplemented and replaced by non-clone human recruits drawn from the Stormtrooper Corps. They were sometimes assigned to an Inquisitor, as in the case of two Purge troopers serving under the Second Sister in her hunt for Cal Kestis. They are regularly deployed in imperial structures and the Inquisitorial fortress.
