The author gives a full background, the story of the long development of this tank (which was never given a name), and its eventual use and modifications. It makes for a most interesting history of this big, Cold War tank and is a book that deserves a place on the shelf of any armor enthusiast.

A fine survey that considers the M103 heavy tank as an example of the design trends of the post-World War II Army. The M103 saw years of service and though it was not at the top of the Army's list of equipment, it was the only weapon system that could face the Soviet heavy tanks. Eventually the Army realized this, and the M103 saw plenty of action in which it performed in outstanding battles documented here. Any collection strong in World War II military equipment will find this a winner!
