Good book to understand the mythical Tiger tank, how it was employed, what the purpose was behind the design, and the organization of the units that employed it. After reading this book you will understand there is a lot more to tanks than the size of the gun and the thickness of the armor. Tanks require lots of care and maintenance, cost a lot to operate, and need highly trained crews. This book will give the reader a good understanding of how Heer employed the Tiger, and why, and the limitations of tanks and in particular the Tiger tank.The name "Sledgehammers" seems a little over the top, but it is written well enough. Check it out!
