Rancor Battalion

Rancor Battalion had at least four Advanced Recon Commandos — Clone ARC Commanders Blitz, Colt, Hammer, and Havoc. The battalion consisted of Advanced Recon Force Scout Troopers that were identified by the maroon and grayish-blue markings on their helmets as well as some having maroon lines on their arms. The ARC troopers each customized their ARC trooper armor, with Colt and Hammer customizing it in red and gray color schemes, Havoc customizing it in blue markings, and Blitz in yellow and gray. Members of Rancor Battalion used DC-15A blaster rifles, and at least one RPS-6 rocket launcher. As a battalion in the Grand Army of the Republic, Rancor Battalion was made up of four companies that contained 576 troopers.

The Rancor Battalion was a battalion in the Grand Army of the Republic active during the Clone Wars between the Galactic Republic and the Separatist Alliance. Prior to the defense of Rishi Station, Rancor Battalion was stationed on the planet Kamino where its four Advanced Recon Commandos oversaw the final phases of clone trooper training alongside Jedi General Shaak Ti, Master Chief Bric, and El-Les.

Rancor Battalion was again stationed on Kamino and participated in the Battle of Kamino. Clone ARC Commanders Hammer and Havoc defended the main hangars in Tipoca City and led other clone troopers, while Clone ARC Commander Colt fought near the barracks. ARC Commander Blitz led a trio of ARF troopers in the outside walkways of the city. Eventually, Republic forces prevailed, and members of Rancor Battalion were present in the aftermath and cleanup.

Rancor Battalion first appeared in "Clone Cadets," the first episode of the third season of the animated TV-series Star Wars: The Clone Wars.
