This new title in the 'Duel' series of books from Osprey is written by David Higgins, and it compares two well known heavy tanks used at the end of WW2, the German King Tiger, or Toger II, against the Russian IS II. No doubt due to the huge tank battles that took place on the Eastern Front, both germany and Russia raced to field thee heaviest tank with the longest range armament that could defeat their opponent.
The huge King Tiger found itself pitted against the lighter but heavily armed IS II.
