They were in Operation: Knightfall, assigned to guard the communication room. Many of the Assassins were killed, but most survived. Before that, they were in many other battles. Clone assassins were highly demanded. The Squad was in the Battle of Coruscant. When the 101st Legion was defending the Senate Building by sniping from the roof, the squad was on the ground, slaughtering droids. In the end, they had killed 56,798 battle droids. After Operation: Knightfall, they finished off the rest of the Jedi hiding on Coruscant, then moved off planet.
