Clone assassin

Clone Assassins were one of the ever expanding specializations that Advanced Recon Commandos evolved into during the Clone Wars. When the elusive threat of Count Dooku's compatriots composed of Dark Jedi became to much for even the Jedi Order, the Republic Army High Command deemed the creation of an elite unit to combat the growing menace needed. Selected from second generation A.R.C.s, the Clone Assassin Corp was trained and disciplined for the sole purpose of taking down any form of force sensitives classified as enemies of the Galactic Republic. In order to effectively confront their would be adversaries, any form of assistance was carefully researched. From agility enhancing stims to Advanced Jedi flow techniques and even black market far-ranging weapons technology.

Clone sharpshooters
Clone Assassins were based upon the same genetic template used in the creation of ARC troopers. During the Clone Wars, clone assassins were used as snipers. Most were at a captain rank. All snipers had to get special training to improve their eyesight so that they could use their sniper rifle to take out any enemy threats in the battlefield. Armed with a DC-15x sniper rifle, DC-15s blaster pistol sidearm, and three Merr-Sonn V-1 thermal detonators, a clone sharpshooter provided accurate, long-range firepower to the Republic forces. In addition, each sharpshooter carried an Arakyd R-1 recon droid that could be used to locate entrenched enemy positions and call down an orbital strike from a Republic cruiser.

Others
Other assassin clones were trained in hand-to-hand combat and Teräs Käsi, and were equipped with wrist vibro-blades. They were so well trained, that they were able to avoid lightsaber attacks.

One of their most important and last actions, the elite members of the Corp was deployed to the Jedi Temple to ensure the potent execution of the said-to-be-traitorous Jedi Knights ordered by Emperor Palpatine. After purging the Jedi Temple, Darth Vader assigned them to protect the Jedi Communication Center that would lure the last of the Jedi in the Galaxy into the final moments of their Order. As a last ditch effort to save the remaining Jedi, Former General Obi-Wan Kenobi and Jedi Grand Master Yoda infiltrated the Jedi Temple to reprogram the ensnared message. Even with their incredible prowess and greater numbers, the majority of the Corp were overrun and died knowing that they perished in the hands of the two most powerful force sensitives in the galaxy. The Assassin Corp was never reestablished after their uneventful life and tragic death.

The future of the Assassins
From their ashes rose the few who survived, they were rumored to have been reassigned serving as advanced training overseers for the Galactic Empire's rising new elite purge forces, namely the Inquisitorius, 501st "Vader's Hand" Legion, Coruscant Guards and Storm Commandos. They shared these responsibilities with the Emperor's own, the Emperor's Royal Guards.

Appearances
In Star Wars: Battlefront and Star Wars: Battlefront II, clone assassins were used as snipers. Most have a rank of captain. All assassins were required to have special training to improve their eyesight so that they could use their sniper rifle to take out any enemy threats in the battlefield efficiently.
