Fortress Osprey

This book tells the story of these Soviet defensive systems, their design, construction, and combat history. With excellent illustrations, it describes the standard types of construction and the weapons they contained. The text is a model of clarity, which puts the complicated history into a coherent narrative, and the maps, while not numerous, are effective. The book closes with suggestions for places to visit remains of the Russian defenses. This is one of the best-written books in the series, and is highly recommended even to those unfamiliar with Soviet fortifications.
