In the introduction to this very interesting book, military expert Hanson W. Baldwin writes ""the weapons of World War II bridged the great gap between the age of the horse and the age of the missile and atom"". The authors prove this fact as they delve not only into the nature of, but the history and development of hundreds of airplanes, ships, artillery , and other weapons employed from 1939 to 1945 by both sides. Here are the Spitfires, the the B-17's--- here too are the great ships such as the Washington, and Warspite--and here are the tanks, guns, rockets, and other equipment used by the massive land armies. The descriptions, although brief, are usually highly accurate and make reference to other similar weapons. Sometimes, as for instance in the case of the German U. Boats, the information is slightly erroneous, but this is unusual. Over illustrations accompany the descriptions. An excellent book for men, and one well timed for Christmas buying.
