The Great Patriotic War lasted for four years and like all wars it was a terrible thing. The Soviets were about to be defeated at the gates of Moscow when they got an unexpected break in 1942 thanks to Hitler's mistake; he relocated many armament factories far away from battlefronts, giving the Red Army time enough to strengthen their forces with new units before taking on Germany again head-on.
The Germans underestimated the Soviet Union: in 1941 Nazi troops invaded Russia but by 1943 they had no chance against them as Red Army defended their Motherland relentlessly.
With improvements in combat tactics and staff training, alongside evolutions in the design of armored fighting vehicles, in May 1945 the Soviet Union achieved a crushing victory against the German forces.

This book provides a general view on the military operations from the invasion of the USSR to the defeat of the Third Reich and focused on the evolutions of Soviet armored units. Authors discuss organization, equipment, different models of fighting vehicles and their variations in design over time - an all-inclusive text for those interested in history or modern warfare.
