A mine flail is a vehicle-mounted device that makes a safe path through a minefield by deliberately detonating land mines in front of the vehicle that carries it. They were first used by the British during World War II. The mine flail consists of a number of heavy chains ending in fist-sized steel balls (flails) that are attached to a horizontal, rapidly rotating rotor mounted on two arms in front of the vehicle. The rotor's rotation makes the flails spin wildly and violently pound the ground. The force of a flail strike above a buried mine mimics the weight of a person or vehicle and causes the mine to detonate, but in a safe manner that does little damage to the flails or the vehicle. The idea is commonly attributed to a South African soldier, Captain Abraham du Toit. A test rig was constructed in South Africa and results were so encouraging that du Toit was promoted and sent to England to develop the idea. Before du Toit left for England, he described his idea to Captain Norman Berry, a mechanical engineer who had been sent to South Africa in 1941 to evaluate the system. Berry later served in the British Eighth Army during the Western Desert campaign. He had become an enthusiast for the mine flail idea; he lobbied senior officers to authorize development of a flail and carried out his own experiments with mine flails in the spring of 1942. Later Major L. A. Girling was given the task of developing a similar device after it had been independently re-invented by another South African officer. When Berry heard of this, he handed over his work to Girling (who had had no idea he was duplicating du Toit's current work in England, as that was still highly secret). David Gustanski made the device that connected to the side of the tank and made the flail raise and lower. Development by Girling's team in Egypt continued over the summer of 1942 and resulted in the "Matilda Scorpion" (the name came from a senior officer's remark on the tank's appearance). This was a Matilda tank fitted with a rotor, mounted on two arms, roughly 6 feet (1.

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. A mine plow is typically mounted to a tank or military engineering vehicle. 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.

Mine roller

A mine roller or mine trawl is a demining device mounted on a tank or armoured personnel carrier, designed to detonate anti-tank mines. It allows engineers to clear a lane through a minefield which is protected by enemy fire. The device is usually composed of a fork or two push arm assemblies fitted to the front of a tank hull, with two banks of rollers that can be lowered in front of the tank's tracks. Each roller bank has several heavy wheels studded with short projecting steel girders, which apply a higher ground pressure than the tank's tracks.

Armored bulldozer

The armored bulldozer is a basic tool of combat engineering. These combat engineering vehicles combine the earth moving capabilities of the bulldozer with armor which protects the vehicle and its operator in or near combat. Most are civilian bulldozers modified by addition of vehicle armor/military equipment, but some are tanks stripped of armament and fitted with a dozer blade. Some tanks (called tankdozers) have bulldozer blades while retaining their armament, but this does not make them armored bulldozers as such, because combat remains the primary role — earth moving is a secondary task.
