Jek

Jek was a clone trooper of the Coruscant Guard and later the Ranger Corps during the Clone Wars. Some of his companions included Yoda, Rys, and Thire. He was known to be a heavy weapons specialist before his time with Yoda on Rugusa, after which he decided to retrain as a clone scout trooper. During Order 66, Jek (at this time a captain) was on Kashyyyk guarding Yoda with Commander Gree. Along with Gree, Jek attempted to assassinate Yoda but failed due to him sensing the threat and decapitating both clones.

Appearance
Jek, like Rys, bore many red markings on his Phase I clone trooper armor, like on the visor of his helmet, gloves, and shoulder pads, as well as other areas. Being a heavy weapons specialist, Jek carried a Z-6 rotary blaster cannon and an RPS-6 rocket launcher in battle and had at least three thermal detonators on his person. His armor also featured a bandoleer that held extra ammo and two holsters for the dual DC-17 blaster pistols he wielded. During the Battle on Kashyyyk, Jek wore scout trooper armor, and carried a  DC-15S blaster carbine.
