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.
CT-1824, known as "Spin," is the group's sniper and scout. He was selected for the Knightwatch for executing Order 66 when his commander hesitated to initiate the attack. The Jedi target, sensing the commander's hesitancy and doubt, could well have escaped had he not been blindsided by Spin's complete lack of emotion and surprise attack.
Spin's combat kit consists of a senosr-pack, modified stealth variant Katarn-class armor, enhanced helmet sensors with omni-spectrum attachment, as well as a DC-17m with custom sniper attachment.
