It is unique in the fact how it's actually designed more for anti-aircraft usage, but isn't completely classified as an anti-aircraft vehicle. The 4 cannons fire 15x75mm projectiles, that can even threaten tanks. Avalonia gives the license to use and produce this vehicle to the other members of the Iron Entente.
