This publication is dedicated to the history of the “wartime heavy tank”, which bore the name “Leader of All Nations”. Despite the fact that the tank is not one of the little-known, domestic authors do not indulge it with their attention. The album we bring to your attention contains a brief history of the creation of this tank, written based on a study of documents from the People's Commissariat of the Tank Industry. The People's Commissariat of Armaments, the Chelyabinsk Kirov Plant, as well as the Museum of Artillery, the Engineering and Signal Troops, the Museum of Armored Weapons and Equipment, NII-48 and the Main Armored Directorate.
