The BL-1T Riot Suppression Droid was a type of riot battle droid used as security forces by the Selkath species on the planet Manaan during the Galactic War between the Galactic Republic and the Sith Empire. BL-1T Droids resembled other Selkath humanoid models, with white plating and a blue sensor, and they used a blaster pistol in combat along with a powerful riot shield—which could be transferred to others—and a riot grappling cable. Sairisi, the security chief at Genetics Laboratory G-1, used two BL-1Ts, and they were destroyed when Sairisi was killed during a covert raid on the facility.
