Rhell was once a simple fighter pilot in the Republic army, but rose to the Rank of Captain (and XO) of the Shield of the Republic. He barely survived the chaos of the Clone Wars, but kept a few members of the squad together. He recruited more until he had a full wing and used this to take down as many Imperial ships as he could. He has since joined the Rebellion and been station at Teirfon.
He is wing commander of Tierfon, but prefers to personally lead Tierfon 3 (Green Squadron) called “The Shield of the Rebellion.” They are the A-wing reconnaissance squad of the three-squadron wing. Their squadron patch is a golden shield with the Rebel Alliance sigil on it. Two swords are crossed behind the shield.
