"Born" on Kamino, as all clones were, Clone Surveyor-Sharpshooter 2852 - or "Jitter" - was given extensive training in long arms and long range dispatch tactics. He was given his unique title due to his propensity towards skittishness and paranoia; though over time, his jitteriness grew to not hinder his aiming.
Jitter participated in the Battle of Geonosis as a scout and sniper, reporting the location of enemy encampments and ambush points as well as maintaining general surveillance of the CIS forces, while also eliminating threats from afar as necessary.
Jitter continued his training after the battle, attempting to further hone his aiming and perceptive capabilities; which is where he is today.

Jitter's primary motivation for his actions is simple; he wishes to see the CIS crushed, and the Republic standing victorious.
His reason for desiring this is also simple; he believes the Republic to be a shining beacon, a symbol of what is right in the galaxy. He is, by all accounts, as much of a patriot as a clone can be... Though he will rarely - if ever - publicly voice this.

Intelligence. Jitter is well-aware that to achieve victory in any and every confrontation, one must know their enemy; what they're planning, what their troop composition and numbers are, their access to armored vehicles, locating key weaknesses in said enemies' defenses for rapid engagement and sabotage, et cetera. Jitter's desire to attain intelligence extends beyond this, however, and even into their logistics; how advanced their technology is in comparison to his own forces', their economic power, and other aspects of the CIS that some would consider irrelevant in comparison to how many droids they can send down.

Intelligence Duty: Standard - 5 (+5 Starting XP)

His armor - standard-issue clone captain armor (complete with red stripes), which Jitter misidentified as marksman armor before claiming it for himself preceding his first deployment - bears a self-painted brown pauldron, as well as a decorative, muted-green scarf. Most of his armor is covered in a mess of webbing, pouches and straps to secure his backpack, utility belt and load-bearing gear in place.
