A company of clone troopers was part of the Grand Army of the Republic. This group was positioned at Rishi Station, located on the Rishi Moon, throughout the Clone Wars conflict that raged between the Galactic Republic and the Confederacy of Independent Systems. This particular unit was under the command of Clone Sergeant O'Niner, and its ranks included the clones known as CT-327, Hevy, Echo, Droidbait, Cutup, Fives, and Nub. Following the Defense of Rishi Station, Echo and Fives, the only survivors, were welcomed into the ranks of the 501st Legion.
