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. This ensures the explosion of pressure-fused anti-tank mines, which would otherwise explode under the track itself. [1]

History

At the end of the First World War, the British Army Engineers Major Giffard Le Quesne Martel and Major Charles Inglis experimented with tank bridges and mine rollers based on the Mark V tank. Three special tank battalions were mustered for trials at Christchurch in Hampshire, England, in 1918. Because of the Armistice, these were never tested in battle, but some development work continued with the Experimental Bridging Company until 1925.

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. Prototypes were tested based on the T-28 medium tank in 1940. Development was interrupted by the start of World War II, but resumed in 1942. T-60 and KV tank chassis underwent trials, but only the T-34 was deemed to have a sufficiently robust transmission and clutch.

Experimental detachments of PT-34 mine roller tanks were formed in May 1942, and saw action at Voronezh in August. The first Independent Engineer Tank Regiment with eighteen mine rollers was fielded in October 1943. At least five regiments were formed during the war.

The PT-34's huge roller fork was semi-permanently mounted on a T-34 or T-34-85 tank. The rollers were usually removed for travel, and only installed for mine clearing operations. Adaptations for later tanks consisted of two lighter arms. The Mugalev system was adopted by U.S. and Israeli forces in the 1980s.

During WWII, the Germans created the experimental Räumer S 4-wheeled armoured mine clearance vehicle, built by Krupp. Weighing 130 tons, the prototype was captured by the Americans at the end of the war.

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. [2]

During World War II, the mine roller most used by US forces was the T1E3 Mine Exploder unit, attached to the M4 Sherman medium tank. It was nicknamed Aunt Jemima because of its pancake-like appearance. [1] It had two sets of five disc rollers, 10 feet (3.0 meters) in diameter each.

Post WW2

Since 1945, a number of countries have developed mine rollers including:

A military engineering vehicle is a vehicle built for construction work or for the transportation of combat engineers on the battlefield. These vehicles may be modified civilian equipment or purpose-built military vehicles. The first appearance of such vehicles coincided with the appearance of the first tanks, these vehicles were modified Mark V tanks for bridging and mine clearance. Modern military engineering vehicles are expected to fulfill numerous roles, as such they undertake numerous forms, examples of roles include; bulldozers, cranes, graders, excavators, dump trucks, breaching vehicles, bridging vehicles, military ferries, amphibious crossing vehicles, and combat engineer section carriers.

<span class="mw-page-title-main">Land mine</span> Explosive weapon, concealed under or on the ground

A land mine, or landmine, is an explosive weapon concealed under or camouflaged on the ground, and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it.

<span class="mw-page-title-main">Mine plow</span> Device to clear minefield

A mine plow 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.

The M4 Sherman tank was produced in several variants, a result of mass production spread across several manufacturers and several years. It was also the basis for a number of related vehicles and Shermans have been modified by several nations, ranging from upgrades to complete hull conversions for another task. Originally designed in 1941, M4 variants were still used by Israel during the 1967 and 1973 wars with its Arab neighbors.

The Giant Viper was a trailer-mounted, vehicle-pulled, mine clearance system, designed to be deployed in areas containing land mines. It was developed for the British Army in the 1950s. It was designed to be towed behind a Centurion gun tank, FV4003, AVRE ; and also the FV432 Armoured personnel carrier.

The L9 bar mine is a large rectangular British anti-tank landmine. The bar mine's principal advantage is its long length, and therefore its trigger length. A typical anti-tank landmine is circular, and a vehicle's wheels or tracks, which make up only a small proportion of its total width, must actually press on the mine to activate it. To increase the probability of a vehicle striking the mine, the mine's effective trigger width must be increased.

An armoured vehicle-launched bridge (AVLB) is a combat support vehicle, sometimes regarded as a subtype of military engineering vehicle, designed to assist militaries in rapidly deploying tanks and other armoured fighting vehicles across gap-type obstacles, such as rivers. The AVLB is usually a tracked vehicle converted from a tank chassis to carry a folding metal bridge instead of weapons. The AVLB's job is to allow armoured or infantry units to cross craters, anti-tank ditches, blown bridges, railroad cuts, canals, rivers and ravines, when a river too deep for vehicles to wade through is reached, and no bridge is conveniently located, or sufficiently sturdy, a substantial concern when moving 60-ton tanks.

The 1st Assault Brigade Royal Engineers was a specialised armoured formation of the British Army active in the Second World War. It was formed in mid-1943 and its structure was three assault regiments of the Royal Engineers. It was assigned to the 79th Armoured Division in preparation for the Normandy invasion of 6 June 1944. The unit comprised armoured vehicles modified for specialist roles, intended to assist with the landing phase of the operation.

A mine-clearing line charge is a device used to create a breach in minefields under combat conditions. While there are many types, the basic design is for many explosive charges connected on a line to be projected onto the minefield and then exploded, detonating any buried mines, thus clearing a path for troops to cross.

<span class="mw-page-title-main">T-26 variants</span> Vehicles based on the Soviet T-26 light tank

More than 50 different modifications and experimental vehicles based on the T-26 light infantry tank chassis were developed in the USSR in the 1930s, with 23 modifications going into series production. The majority were armoured combat vehicles: flame tanks, artillery tractors, radio-controlled tanks (teletanks), military engineering vehicles, self-propelled guns and armoured personnel carriers. They were developed at the Leningrad Factory of Experimental Mechanical Engineering by talented Soviet engineers P.N. Syachentov, S.A. Ginzburg, L.S. Troyanov, N.V. Tseits, B.A. Andryhevich, M.P. Zigel and others. Many Soviet tank engineers were declared "enemies of the nation" and repressed during Stalin's Great Purge from the middle of the 1930s. As a result, work on self-propelled guns and armoured carriers ceased in the USSR during that time. T-26 light tanks were also modified into armoured combat vehicles in the field during wartime.
