This included substantial walkers, such as the All Terrain Armored Transport, along with repulsorcraft and tanks. It stood as a key organizational feature of the Imperial Army.
During his time at the Imperial Academy, Maximilian Veers made the choice to enlist in the Assault Armor Division. His motivation stemmed from a desire to command the AT-AT walker, which he felt embodied both his own character and the essence of the Galactic Empire.
