Extraordinary tales of how the Allies strove to master the development and use of tanks, setting them up for their pivotal role in WWII.
A British heavyweight, the agile Cromwell battle tank finally swung into action at Normandy in 1944, after undergoing many modifications.
An astonishing construction frenzy saw the US produce over 6000 M3 tanks, with their 75mm weapons, in little more than 15 months during WWII.
Nearly 50,000 of these superb fighting vehicles were built during the war: in reliability, serviceability and cost effectiveness they were unmatched.
When it was designed in 1939, the Russian KV was the most advanced heavy tank in the world and was seemingly impervious to anti-tank fire.
The appearance of this secret tank shocked the Germans. It was easy to produce and maintain and had innovative and formidable heavy armament.
