ARC Troopers, formally known as Advanced Recon Commandos, were elite clone troopers who served the Republic during the Clone Wars. They were usually sent on various combat missions that other clones could not accomplish. While this was the case for most ARC Troopers, several other ARCs chose to remain on Kamino to observe Clone Cadet training and to pick out potential ARC Trooper candidates from the latest batch of Cadets.
