This book evaluates the PzKpfw III and T-34 medium tanks fielded by Germany and the Soviet Union during 1941. Both designs were intended to be the primary medium tanks of their respective armies, but owing to manufacturing difficulties, neither was available in quite the numbers intended. Even though both tanks were relatively new, neither was deemed entirely satisfactory, and replacements for both were already on the drawing board. Nevertheless, it was these tanks that clashed in what the Soviet Union called the Great Patriotic War.

While the T-34 rapidly established a fearsome reputation only sometimes borne out by its actual performance, the PzKpfw lII was smaller, lighter, and not as well armed as its Soviet opponent but benefited from the support of a more seasoned and better structured army. Full-colour artwork, archive photographs and authoritative text drawing upon Russian- and German-language sources combine to reveal how the Germans harnessed the advantages of combat experience and superior organization to counter the T-34's tactical strengths, but also how the PzKpfw III quickly lost relevance as it became evident that it could not carry a gun powerful enough to destroy the T-34 at range.
