A man from the Sverdlov region (Russia), Alexander Porubaiko, has built a copy of a German tank Panzerkampfwagen IV Ausf. F2 in accord with the drawings he had found, using details of trucks and tractors. The tank can drive, its turret rotates, changes a tank gun cant angle.
Unfortunately it's not armoured. But even without it the tank weighs 10 tons, such vehicle cannot drive along roads.
