The RT-8 "Berggeit" (english: "mountain goat") was a successful light tank design in the Kooplieden Armed Force's RT-series developed for use in mountainous and terrain typically inaccessible to tanks. Lightly armed and armoured, but boasting a large anti-infantry armament, good manoeuvrability, high speed, and good climbing performance, the RT-8 was used extensively by the Kooplieden Monarchy Preservation Force in the Anwnn Civil War.
