"Colt" was the nickname of an Advanced Recon Commando who served in the Grand Army of the Republic during the Clone Wars.Commander of the Rancor Battalion and an advocate of unity on the battlefield, Colt was assigned to Tipoca City on Kamino to select potential ARC trooper candidates from squads of clone cadetsnearing the end of their training. The ARC trooper was still on Kamino when the Confederacy of Independent Systems launched an attackon the cloning facilities. Colt participated in the defense of TipocaCity but was killed by the Confederate Dark Jedi Asajj Ventress.

An expert in ground and aquatic warfare,^[6] Colt believed strongly in the unity of and brotherhood between his fellow clone troopers—especially when in battle—and stressed this lesson to the clone cadets whose training he was assigned to supervise. Bravo Squad's performance, specifically, greatly impressed the Commander—the cadets had completed their trial run in record "ARC trooper" time and had performed their final test flawlessly. His evaluation of Domino Squad, conversely, was quite different—the cadets' shoddy handling of the Citadel Challenge had revealed their disunity and noncompliance, and Colt wasted no time in berating them for their mistakes.^[4] When faced with a Separatist attack on Tipoca City, Colt and other clones fought against invading battle droids despite overwhelming odds. The Commander continued to fight even after his comrades were killed, until he himself was struck down in battle.^[3] The pattern on his helmet identified Colt as a member of the Rancor Battalion.^[6]
