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.
CP-1337, known as "Clack", is the only Clone Trooper Private serving in Knightwatch. As a "soft-shell" (clones trained for technical tasks rather than combat) Clack is deployed with the Commandos whenever a situation calls for advanced onsite expertise. Clack is also responsible for keeping the group's armor and weaponry in premium condition.
Clack's field kit consists of of a standard "soft-shell" helmet, reinforced tactical blast vest with various tools, standard DC-15s blaster carbine, and a compact "fast fix" tech welder.
