M6 Heavy Tank(MM05)

M6 Heavy Tank(MM05) Development At the outbreak of World War II the US Army possessed few tanks, and no heavy tanks. In May 1940 the US Army Ordnance Department started to work on the T1, 50-ton heavy multi-turreted tank. This was similar in concept to the Soviet T-35 and other 1930s ‘land battleship’ designs.

By October 1940, the Department reached the same conclusions of excessive size, difficulty in crew co-ordination and high production cost that had led to the abandonment of the land battleship concept in Europe.  A new T1 heavy tank design was laid down with a single turret retaining the mixed armament of the earlier design. The turret mounted a stabilized 3 inch gun with a coaxial 37mm gun with a loader and ammunition handler to keep up the rate of fire. Initially the design had six machine-guns, but this was cut to four in the production vehicles.

These were twin .50 cal machine guns in a bow mount, a fixed .30 cal machine-gun of dubious value in the front plate fired by the driver, and a .50 cal machine-gun on the commander’s hatch. On 26 May 1942 a cast-hull T1E2 and a welded-hull T1E3 were standardised for production as the M6 and M6A1 respectively. The initial plan was to produce 5000 tanks at 250 tanks per month, but this was soon cut to a more realistic 115 tanks in the first production run starting in December 1942. Hypothetical Combat Service By the time the M6 was ready for production, the Armored Corps had lost interest, preferring the more mobile M4 medium tank. However, the appearance of the German Tiger heavy tank made them reconsider. M6 heavy tanks operated in Tunisia with most tank battalions having a platoon.

They proved their worth as their 3-inch guns were one of the few weapons capable of knocking out a Tiger and their thick armour enabled them to withstand return fire. Design Features When the specifications were laid down for the M6 heavy tank it was normal for heavy tanks, such as the Soviet T-35, to follow the ‘land battleship’ model, having multiple turrets mounting a variety of guns and machine-guns. The T1 heavy tank specification featured a slightly more modern arrangement with both of its guns mounted in the same turret and its twin .50 cal machine-guns in a relatively conventional bow mounting.

In Flames Of War The M6 heavy tank is a ‘land battleship’ with multiple guns. It has a 3-inch anti-tank gun for use against heavy tanks, a 37mm gun for use against lighter armoured vehicles, and twin .50 cal machine-guns to dig infantry out of trenches. Weapon M7 3in gun Range: 32"/80cm; ROF: 2; Anti-tank:12; Firepower: 3+; Co-ax mount, Stabiliser M6 37mm gun Range: 24"/60cm; ROF: 3; Anti-tank: 7; Firepower: 4+; Co-ax mount, Stabiliser Twin .50 cal MG Range: 16"/40cm; ROF: 4; Anti-tank: 4; Firepower: 5+; Hull mounted, Twin MG, ROF 2 if other weapons fire Armour Front: 8; Side 6; Top: 2 Equipment & Notes .50 cal AA MG, Slow tank, Unreliable, Wide tracks

It can fire both of its main guns at the same time using the Multiple Weapons rule on page 85 of the rulebook. With two loaders the M6 heavy tank can fire the 3in and 37mm guns together, treating one of the guns as having ROF 1. Designed by Evan Allen Painted by Jeremy Painter
