The Security Turret was an automated turret used in Butcher Bay Correctional Facility. Most of them attack if any inmates, such as Riddick, show hostile behavior, though some attack if someone crosses an invisible laser near the turret. Most of the turrets are stationary, but there are some in the Double Slam section that move on rails.
On Single Max turrets there is a word "Cthulhu!" carved on them.
