Chairman Khasan Parry led the 4th Armored Division contingent deployed to Sevon immediately prior to the SLDF invasion of the world in late 2581. The 4th Armored Division detachment consisted of a mixed regiment of armor and infantry supported by two squadrons of AeroSpace Fighters and two companies of BattleMechs. The 4th Armored Division and acted in support of the Pitcairn Legion, who were also deployed to Sevon, and fought against the Star League forces until they were ordered to retreat from the world by Alliance President Grigori Avellar. Although the Sevon militia were ultimately defeated, the battle on Sevon stymied SLDF operations for the remainder of the year and Sevon would continue to resist. It isn't known if Khasan Parry survived the battle for Sevon.
