Cassio Tagge was served as the head of the Imperial Army and as a member of the Joint Chiefs of the Imperial military during the reign of the Galactic Empire. General Tagge, who was born into the powerful House of Tagge, the owners of TaggeCo mining operations, was stationed on Coruscant, where he had access to the upper-levels of the Imperial Palace.
Shortly before the Battle of Yavin, Tagge was stationed aboard the Death Star. During a meeting of the Joint Chiefs aboard the Death Star, Tagge argued with Admiral Antonio Motti, who did not share Tagge's view that the Rebel Alliance, which had stolen plans to the Death Star, represented a threat to the Empire and to the Death Star.
