The Soviet T-34 medium tank needs no introduction, being the most famous tank ever built especially as has seen service across the globe throughout the twentieth century's most brutal wars. However, despite this fame, little has been written about its design changes. While most tank enthusiasts can differentiate between the 'T-34/76' and the 'T-34-85', identifying different factory production batches has proven more elusive. Until now.

With nearly six hundred photographs, mostly taken by soldiers who both operated and fought against the T-34, this book seeks to catalog and contextualize even the subtlest details to create a true 'T-34 continuum'.

The book begins with the antecedents of the T-34, the ill-fated BT 'fast tank' series and the influence of the traumatic Spanish Civil War before moving to an in-depth look at the T-34's prototypes. After this, every factory production change is catalogued and contextualized, with never-before-seen photographs and stunning technical drawings. Furthermore, four battle stories are also integrated to explain the changing battle context when major production changes take place. The production story is completed with sections on the T-34's postwar production (and modification) by Czechoslovakia, Poland, and the People's Republic of China, as well as T-34 variants.
