Mine plow

A mine plow (plough in British English) is a device designed to clear a lane through a minefield, allowing other vehicles to follow.

Buried land mines are plowed up and pushed outside the tank's track path or tipped over.

Since modern anti-tank mines rely on a focused explosion to destroy armored vehicles, they are useless when turned upside-down; as the tank runs over the mine, it will expend its blast down instead of upwards, causing insignificant damage, if any.

Towards the end of the First World War, the French mounted a plow on their Renault FT tank.

[1] The first recorded combat use is by a "Bullshorn" plow on a Churchill tank of the British 79th Armoured Division, on Sword Beach during the Allied invasion of Normandy (this was one of "Hobart's Funnies" specialized vehicles).
