Skorpius Hover Tank
A vehicle utilized exclusively by the Skitarii, the Skorpius basically serves the same function as a Rhino, with both transport and battle tank variants. Except it's a hovercraft. Not fancy anti-grav tech either, it's pretty much just a conventional hovercraft. Apparently just floating an armored vehicle on regular old air (something we could do in friggin M2) is now barely understood, deadly technology from the Age of Darkness. There also the brickest, vehicle gameworkshop have yet made, and that's saying something.
Skorpius Dunerider
The Higgins Boat of 40k, the Dunerider works exactly the same as the WWII Landing Craft that inspired it: hit the beach battlefield, suppress enemies with the many stubbers mounted on it, and then drop the front ramp and have the Skitarii within re-enact the opening scene of Saving Private Ryan. It's basically a smaller and more advanced version of the Gorgon Transport.
Skorpius Disintegrator
A battle tank variant of the dunerider. Looks similar to a rubber duck, oddly enough.
