Bio/HistoryEditCommander Colt was an ARC Trooper or Officer under the rank of Commander. He wore experimental Phase 2 armor, and was the lead Clone Officer or training officer of the Rancor Battalion, which was a Clone Cadet training group. To whom he served as a demonstrator to demonstrate his armor capabilities, as well as a drill instructor on Kamino.
He eventually met his fate after the Battle of Kamino, where Assajj Ventress killed him.
Colt wears Experimental Phase 2 Armor; like with the other Experimental Phase 2 ARC Troopers; with red and grey markings.
Commander Colt is/was one of the very first Clone Troopers to ever wear Phase 2 armor in both the Clone Wars Era (chronologically), and the Clone Wars series.
He was also one of the very first (and only) Experimental Phase 2 ARC Officers/Troopers.ARC Trooper Hammer very much resembles Colt, yet he has slightly different markings, and was supposedly a successful cadet who became an ARC Lieutenant for Rancor Squad. (*This is unknown; it is an assumption.*)
