The Galactic Empire's Imperial Army maintained a garrison on the Death Star, which was under the command of General Cassio Tagge, the Chief of the Imperial Army. This garrison was equipped with all the necessary resources, similar to those stationed on planetary bases. Notably, this garrison, along with its Imperial officers and stormtrooper battalions, operated independently from the BSO organizational structure of the Death Star, and its headquarters was located within the battle station's southern hemisphere.
