No mercy! No retreat, and most of all no noise!
—RC-2799
The Galactic Republic Special Operations Unit was a top secret unit of clone troopers who had been selected by the leader of this unit for acing the tryouts of units like the 501st. Their skills matched those of Sharpshooter squad and in order to be top secret they were located on Hoth where even the alliance could not locate them, though the alliance placed their base of operations only two miles away from the booby trapped entrance to their base.

Station 23-452[]
A company of Special Ops troopers took a cloaked shuttle into the hanger of a separatist battle station in order to take control of it. When they landed and de-cloaked, a large battle erupted in the hanger and a small group of clones sneaked away in the confusion. This group succeeded in taking control of the control room of the station. The company then cleared off as the 212th attack battalion descended.
