This paper model is a Mark I (MK I) Whirlwind Artillery Tank, an Imperial artillery support vehicle based upon the Standard Template Construct (STC) Rhino Armoured Personnel Carrier (APC) chassis that is now primarily used by the Space Marine Chapters of the Adeptus Astartes, based on the game Warhammer 40K, the papercraft was created by Patoroch. There is another Whirlwind paper craft model at the site: Warhammer 40K – Fire Lords Mule Whirlwind Free Paper Model.
Originally deployed as part of Space Marine armies, the Mark I Whirlwind was an earlier variant of the standard Astartes artillery support vehicle. It possesses a distinctive shape with its functional-looking, boxy Whirlwind Multiple Missile Launcher. This older Whirlwind is still to be found as a part of many military forces in use across the Imperium of Man. It is armed with linked barrages of Vengeance Missiles and, like its Rhino cousin, a Pintle-mounted Storm Bolter and smoke grenade launchers for defensive purposes. Its crew complement includes a driver, a co-driver/gunner and a two-man missile weapons team.
