The Ion Age 15mm Releases. The five different tracked variants of our mighty Taranis Type 40 Tracked Main Battle Tank are now released! Designed by industry legend Bob Naismith this tank is a large resin and white metal kit in 15mm scale suitable not only for space opera settings but also near future or many other wargaming genres. There are five different variants (A,B,C,D and E) of IAF100 Taranis Tracked Main Battle Tank. Each is about 90mm long and 60mm wide. A beast of an MBT! Thanks. GBS
