The book covers all major variants and sub-variants including the KV-1, KV-1S, KV-85, KV-2, KV-8 and SU-152. It draws upon wartime Soviet documents and technical manuals, factory archive material and other primary source references to provide the most in-depth treatment of the KV series ever published.

The majority of the photographs come from private sources and less than 10% have been previously published. They include rarely seen top views, interior photographs of the KV-1 and SU-152, along with previously unpublished photographs providing glimpses of the turret interior on the KV-2.

The book is accompanied by a web site www.4bogreen.com containing modeling-related information including kit reviews, lists of available after-market products and tweaks lists. By utilizing the web site to complement the book, the author and publisher can more easily include information about new kits and after-market products as they become available.
