Forty & Forty. On the battlefields of Europe and North Africa during the Second World War, tanks played a key role, and the intense pressure of combat drove forward tank design and tactics at an extraordinary rate. In a few years, on all sides, tank warfare was transformed. This title shows how the harsh experience of the German blitzkrieg campaigns in Poland, France, and the Soviet Union compelled the Western Allies to reconsider their equipment, organization and tactics - and how the Germans responded to the Allied challenge. 216 pages, 200 B&W photos, 6½"x 9½", hardcover.
