Background
His early life was on the planet of Brentaal IV, son to a minor politician on planet. His education was finished in the Prefsbelt Fleet Academy. In his sdudies he exeled in fleet tactics and counter-insurgency doctrine.
He was offered a commission at 22, promoted to Lieutenant Commander by 25, and field-promoted to Commodore at 27. After a rebel attack killed most of the senior staff during the Tirren Suppression. During said campaing he used precision strikes to cripple the opposition and minimize the civilian casualties and the use of propaganda and fear tactics.
Intelligence later suggested that Russ may have staged pirate attacks on anti-Imperial merchant guilds using repainted TIEs and seized transports — turning once-neutral factions into pro-Empire collaborators out of fear.
