Commissioned after the end of the Clone Wars by the Emperor, "Knightwatch" was the codename given to a select group of Clone veterans assembled for the purpose of hunting down rogue Jedi, Clone deserters, and their supporters. Despite serving a similar purpose, the group operated independently of Vader's 501st.
The Imperial Commandos of Knightwatch are made up solely of former Clone Troopers and Clone Commanders who performed exceptionally during the Clone Wars. Due to the unacceptable rate of rejection of Order 66 by altered Clone castes, like the ARCs, Null-ARCs, and Republic Commandos, it was decided only Troopers and Commanders would be used in the operation to ensure the highest levels of loyalty and adherence to all orders.
CC-0009, known as Triple-Oh-Nine or "Trip," is a model Clone who served with distinction during the Clone Wars and was especially ruthless and efficient in response to Order 66. The Emperor personally selected him to lead the operation, and allowed "Trip" free reign in forming the squad and selecting its members and armament.
Trip's combat kit consists of a comm-pack, modified stealth variant Katarn-class armor, enhanced helmet sensors and added range finder, as well as a standard DC-17m blaster and modified DC-15s sidearm.
