A mine plough (plow in American English) is a tank-mounted device designed to clear a lane through a minefield, allowing other vehicles to follow. Buried land mines are ploughed up and pushed outside the tank's track path or tipped over. Since modern anti-tank mines rely on a focussed explosion to destroy a tank, 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.
The first recorded combat use is by a "Bullshorn" plough 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). The "Bullshorn" was just one of various designs of plough that were tested and used by the British.
The mine plough is still in use by many Combat Engineer units. The Royal Engineers have deployed the Trojan to Afghanistan  where it is usually fitted with a plough on the front, which enables it to clear mines, either detonating them on contact, or pushing them out of the way to clear a safe channel for following vehicles.
