The 909th Snow Detachment was a small brigade of Clone Cold Assault troopers and later on, Imperial Snow Troopers. In the Clone Wars, the detachment fought on several planets such as Felucia, Toola, and Coreillia. After Order 66 on Coreillia, they killed the Jedi General that was with them and proceeded in killing the rest of the droids, and then moved off the planet. They also were seen on Hoth.
