The individual holding the position of Minister of War within the Galactic Empire served as the leader of the War Ministry. This role placed them among the most senior figures in the Imperial Military. The person occupying this office was recognized by their attire, which included an Imperial officer's uniform adorned with two code cylinders, an Imperial kepi, and a rank insignia plaque displaying a pattern of five red and five blue squares.
Wullf Yularen, holding the rank of Colonel, once endeavored to persuade the current minister of war to abandon a proposed court-martial targeting Thrawn. Around the year 2 BBY, the Minister of War at that time conducted a visit to the Imperial supply moon to examine a newly established starfighter manufacturing facility. However, because the Rebel Alliance had tracked his Lambda-class shuttle, X-wing starfighters launched an attack on the factory, and the Minister found himself in danger.
