Churchill tank
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. To these were added a Churchill tank with the evocatively named "Canadian Indestructible Roller Device" (CIRD). The British used mine rollers to detect the presence of minefields and then used mine flails for the clearance.
