Perhaps not a single tank in the 20th century has gained such fame as the Soviet T-34. It was the "thirty-four" that became the symbol of Victory in the Great Patriotic War - hundreds of these combat vehicles, ascended to the pedestal, serve as a monument to the soldiers-liberators both in our country and abroad. It is T-34 who is called "the best tank of the Second World War." But is it? What was the real value of the "thirty-four" on the battlefield? How good is it compared to enemy tanks? How did the assessments and capabilities of the T-34 change during the war? There has never been such a book in Russian military historical literature. This is the first complete encyclopedia that actually closes the topic. This is the result of many years of work by a leading specialist in the history of Soviet armored vehicles.
