Wirut, hailing from Coruscant as a Human male native planet, achieved the officer rank of Sergeant within the Galactic Alliance Guard by 40 ABY. Furthermore, he functioned as a soldier within the 967 Commando, a company composed of GAG troopers considered elite, under the command of Colonel Jacen Solo. In the course of the Second Galactic Civil War, Solo directed him to arrest Cal Omas, the Chief of State of the Galactic Federation of Free Alliances. Despite some misgivings regarding arresting the Galactic Alliance's principal figure, Wirut followed the instructions of his commander's command.
