The German Tiger heavy tank was a monster of a machine that dominated the battlefields of Europe. One of the most feared weapons of World War II, the Tiger gained an aura of invincibility that was only shattered by the introduction of the Sherman Firefly during the summer of 1944. Specifically designed by the British to combat the Tiger, the Sherman Firefly was based on the standard American M4A4 Sherman medium tank, but was fitted with a powerful 17-pounder gun which made it a deadly opponent for the Tiger. This book describes the design and development of these two fierce opponents, analyzing their strengths and weaknesses and assessing their tactics, weaponry and training. Innovative gun-sight artwork puts the reader "inside" the tanks during famous real-life battle scenarios, including the infamous Panzer ace Michael Wittman leading four Tigers into battle against eight Fireflies, a clash of steel that was a victory not only for superior Allied numbers, but also for Allied tactics and engineering.
