driving problems with such a vehicle. A V-hull vehicle uses a wedge-shaped passenger cabin, with the thin edge of the wedge downwards, to divert blast energy away from occupants. Improvised measures such as sandbags in the vehicle floor or bulletproof vests placed on the floor may offer a small measure of protection against tiny mines. Steel plates on the floor and sides and armoured glass will protect the occupants from fragments. Mounting seats from the sides or roof of the vehicle, rather than the floor, will help protect occupants from shocks transmitted through the structure of the vehicle and a four-point seat harness will minimise the chance of injury if the vehicle is flung onto its side or its roof–a mine may throw a vehicle 5 – 10 m from the detonation point. Police and military can use a robot to remove mines from an area. Combat use Anti-tank mines have played an important role in most wars fought since they were first used. Second World War Anti-tank mines played a major role on the Eastern front, where they were used in huge quantities by Soviet troops. The most common AT mines included the TM-41, TM-44, TMSB, YAM-5, and AKS. In the Battle of Kursk, combat engineers laid a staggering 503,663 AT mines, for a density of 1500 mines per kilometer. This was four times greater than what was seen in the Battle of Moscow. Furthermore, mobile detachments were tasked with laying more mines directly in the path of advancing enemy tanks. According to one source: "... Each artillery battalion and, in some cases, each artillery battery, had a mobile reserve of 5 to 8 combat engineers equipped with 4 to 5 mines each. Their function was to mine unguarded tank approaches after the direction of the enemy attack had been definitely ascertained. These mines proved highly effective in stopping and even in destroying many enemy tanks." The Wehrmacht also relied heavily on anti-tank mines to defend the Atlantic Wall, having planted six million mines of all types in Northern France alone. Mines were usually laid in staggered rows about 500 yards (460 meters) deep. Along with the anti-personnel types, there were various model of Tellermines, Topfmines, and Riegel mines. On the Western front, anti-tank mines were responsible for 20-22% of Allied tank losses. Since the majority of these mines were equipped with pressure fuzes (rather than tilt-rods), tanks were
