Russian Heavy Tank IS-3 COBI 2590 - World War II 1:28

You know that:

• Work on the new tank, codenamed Object 703, began in 1944. 
• The Soviet Union was building two prototypes simultaneously. One of them had a hull with an arrow-shaped frontal armour and a turret reminiscent of the obsolete KV tank, and the other one was distinguished by the peculiar modern shape of the tank turret.
• Military Chief for Tank Industry V. A. Malyshev, after demonstrating both prototypes, decided to merge the projects. The tank was thus redesigned and presented to Marshal Zhukov in December.
• The production of the new tank was approved by J. Stalin himself, who also chose the designation bearing his name.
• Although some historical sources speak of the deployment of IS-3 tanks at the end of the war during the capture of Berlin, according to production records the new Soviet tanks did not intervene in any of the battles. This did not happen until much later.
• The world first learned of the IS-3 tank on September 7, 1945, when the Allied victory parade was held in Berlin. For the representatives of the victorious powers, General M. Koenig, Gen. Patton and Gen. B. Robertson, it was not a pleasant surprise. Marshal Zhukov duly enjoyed the parade of tanks in front of the ceremonial grandstand while constantly glancing at the surprised army commanders present. The most calm was shown by Gen. Georege Patton, to whom Zhukov said: 'I see that nothing will upset you Americans. You think you've seen it all."
• Egypt's first deployment of IS-3 tanks against Israel was a disaster. Extremely unreliable propulsion equipment and poorly trained Egyptian crews suffered devastating losses. Of the 100 tanks deployed, 73 were destroyed and the remainder remained unmounted on the battlefield.
• Engine cooling was also a major problem, as it easily overheated. Replenishing 170 litres of water to the cooling system in the desert was a big problem.
• Another infamous tank deployment was the Soviet occupation of Czechoslovakia in 1968.
• Despite all the mistakes, the IS-3 tank was a formidable weapon in the hands of an experienced crew. However, it was expensive to produce, and so production ceased in 1946.
• The last units were retired from the USSR's arsenal in 1985.

Field Marshal Bernard Montgomery on the IS-3 tank:

"The IS-3 is the scariest tank you'll ever see. That is, assuming it even arrives for you to see."
