The First Battalion functioned as a component of the Fifth Infantry within the structure of the Imperial Military. During the year 3643 BBY, this battalion found itself under the command of Lieutenant [Piloc] (/article/piloc), and it was positioned on Balmorra. Their mission involved recovering the schematics for a neutron detonator located inside the remnants of Bugtown. Regrettably, Piloc's lack of skill resulted in the death of Private Suzoku, along with half of the battalion, at the hands of the mutated Colicoids that infested the region. Even after Piloc shot Private Camm for disobeying a direct order, he failed to persuade Privates Ganbar and Erelut to re-enter the area.
