Matoran Military

The Matoran of Mata Nui developed a small paramilitary organization to fight and defend against Makuta's Rahi. It had subdivisions managed by Koro, the more prominent being the Ta-Koro guard, the Le-Koro Gukko force, and the Onu-Koro Ussalry.

Ta-Koro Guard
A force devoted to the defense of Ta-Koro and the surrounding area, the Ta-Koro guard was headed by Jaller, its captain, and would often lay traps for Rahi, one of which accidentally captured an amnesiac Tahu. The Ta-Koro guard was at the head of the military on Mata Nui, and had a system of call signs. The Ta-Koro guard used swords, spears, disks, and shields for their speciality in close-combat. By the time of the Mask of Light crisis, the Ta-Koro guard oversaw a fortress around the city.

Le-Koro Gukko Force
Mata Nui's Air Force, the Gukko and Kahu squads defended Le-Koro and the surrounding area of Le-Wahi against Nui-Rama attacks. This group rode their birds well, wielding dual disk launchers. Led by Kongu, this group could also fight on "foot", "wind-flying" through the trees of the jungle. They were agile in both configurations, and usually fought with guerrilla warfare in ambushes.
