Depa Billaba, a Jedi Master, commanded a battalion sometime in the Clone Wars timeline. On the planet Haruun Kal, situated in the Mid Rim, a battle occurred where the battalion sustained significant casualties, with 90% of its members lost to General [Grievous]'s forces. A mere four troopers survived this devastating encounter: Clone Commander "Grey," Clone Captain "Styles," Clone Sergeant "Soot," and Clone Corporal "Big-Mouth."
