Enforcer droids, also called security droids, represented a class of droid designed for regulatory and supervisory purposes, often with an emphasis on physical power.
At his moisture farm, Owen Lars possessed a KPR security droid. During the events of the Battle of Jedha, Eiram's military employed enforcer droids that were provided by Tilson Graf, who was secretly allied with the Mother of the Path of the Open Hand. Graf also furnished the Mother with a consignment of enforcer droids, intended to safeguard the Path. The Path of the Open Hand, which later evolved into the Path of the Closed Fist, utilized enforcer droids of similar design during the Night of Sorrow. In the era of the Clone Wars, the designation "security droid" typically denoted the OOM-series security droid as deployed by the Trade Federation and the Confederacy of Independent Systems. The KX-series was a security droid model that saw service with the Galactic Empire. The New Republic made use of N5 sentry droids in addition to R1 security droids. The First Order was known for its deployment of the KXFO-series security droid. A security droid model was stationed on the Colossus refueling station in 34 ABY, where they maintained order under the command of Captain Imanuel Doza.
