M4A2(76)W: Emcha With a Long Hand

The Americans considered improving the firepower of the Medium Tank M4 back in September of 1941. A year later, experiments with installing the 76 mm T1 gun into the stock turret commenced. Even though the gun fit, the military was unsatisfied with this rearmament. A decision was made to equip the M4 with the turret from the Medium Tank T23, which did not enter production. This was not hard, since the turret ring diameter was the same.

Shortly before that, the M4 (known in the USSR under the nickname "Emcha") was equipped with wet ammunition racks. These modernized tanks, whose name received the suffix (76)W, went into production in January of 1944. Among them was the M4A2(76)W, the production of which began in May of 1944. The USSR received these tanks under the Lend Lease program.

M24 Chaffee: Test Drive at the End of Lend Lease

Starting in the second half of 1943, the approach to sending British and American Lend Lease armoured vehicles to the USSR changed. Instead of immediate large scale shipments, the Western Allies sent a few samples of new vehicles. If the tank or SPG was satisfactory for the Soviet side, full scale shipments followed.

The first vehicle to arrive on this trial basis was the Light Tank M5A1. By that point, production of light tanks in the USSR was wrapping up, so the American novelty never made it into service. Nevertheless, the USSR received another foreign light tank. This was the Light Tank M24, the best American light tank of WWII.

Dinger Tank

"USSR NKO
BTU HQ of the Voronezh Front
Reconnaissance Dept.
May 3rd, 1943

To the divisional HQ chief
Operational department only

Through POW interrogation, it was established that:

The German army is receiving a new "Dinger" tank. The mass is 65 tons, armament is one 100 mm cannon and two M-42 machineguns. The armour thickness (front and engine compartment) is 90 mm. The crew consists of 6 men.

This type of tank is being built in Austria, at a tank factory in Proll. Mass production began in the fall of 1942.

In addition, infantry units received a new type of anti-tank grenade. The grenade carries three magnets on the front of a round plate. The grenade is used as follows: a tank hunter attaches the grenade to the tank and pulls out the cord (the grenade is held on the tank with magnets), after which the grenade explodes.

Inform your subordinate forces of this kind of tank and anti-tank grenade, make it a priority to clarify data on the type of tank and anti-tank grenade.

Chief of the Armoured and Motorized Department of the Voronezh Front, Lieutenant-Colonel Sch[illegible]enko."
