A battalion served as a component of the Galactic Empire's Imperial Army throughout the invasion of Mon Cala, reporting to Major Rantu. This battalion was among the initial Imperial forces to invade Mon Cala, engaging in the first Battle of Dac City against the Mon Cala planetary defense services. From a command center, Major Rantu oversaw the operation, and was thought to be dead alongside their unit when Mon Cala's defenders obliterated all surface city locations.
