Mine roller

Each roller bank has several heavy wheels studded with short projecting steel girders, which apply a higher ground pressure than the tank's tracks.

After great difficulties caused by minefields in the Winter War against Finland, the Soviet Red Army assigned P.M. Mugalev at the Dormashina Factory in Nikolayev to design a mine-clearing vehicle.

During WWII, the Germans created the experimental Räumer S 4-wheeled armoured mine clearance vehicle, built by Krupp.

[3] The British developed the Anti Mine Roller Attachment (AMRA) for their Matilda II, Valentine, and Crusader tanks in the desert.

The rollers only covered the width of each track rather than clearing a tank-width path for subsequent vehicles and troops.
