The ARC program, also referred to as ARC training, and alternatively known as the Clone Commander training program, was a specific course of instruction undertaken by certain clone troopers within the Grand Army of the Galactic Republic. This training aimed to cultivate leadership skills by fostering independent thought in the troopers. Furthermore, every Advanced Recon Commando was required to complete this program before achieving their designation. This training also prepared Advanced Recon Commandos for the specialized assignments they would be tasked to execute. Individuals such as Neyo and Rex were among the initial one hundred graduates of the ARC program.
