This book examines the technology and strategy that defined the outcome of the battles between the King Tiger and the IS-2. The Soviets had been quick to develop tanks that could fight the Tiger on an equal footing, but these were developed as part of a completely different strategy than that employed by the Germans. The King Tiger was a modern marvel, and remained unmatched in one-on-one combat. Technologically superior, with greater firepower and better armour than the Soviet IS-2, the King Tiger was a formidable opponent. However, the IS-2 was lighter, more manoeuvrable and most importan.
