The First Battalion was a unit within the Fifth Infantry of the Imperial Military. In 3643 BBY the battalion was commanded by Lieutenant Piloc and stationed on Balmorra where it got send to retrieve the plans for a neutron detonator from the ruins of Bugtown. Unfortunately, Piloc's incompetence led to Private Suzoku and half of the battalion killed by the mutated Colicoids infesting the area. Piloc was unable to convince Privates Ganbar and Erelut to go in again, even after he shot Private Camm for ignoring his order.
