The Squadron Detail In Action series was started in 1971. This series covers the development, testing, and production of aircraft, armored vehicles, and ships. The focus of this book is on the M3 Gun Motor Carriage.

At the beginning of World War Two, the United States realized the need for an effective antitank weapon. Through this need, the Military used the M3 halftrack as the base and married it to the M1897A4 75mm gun to create the M3 Gun Motor Carriage. In October, 1941, the first production contract began. By October, 1944, the Gun Motor Carriage was considered obsolete by the U.S. Army. During its career many of these units were used by Great Britain and U.S. Marines well into 1945.

The author, David Doyle, does an excellent job of using photographs and captions to present the development and use of the M3 Gun Motor Carriage. Almost fifty pages of this book are of a restored M3. In these pages, you will find color photos and detailed close-ups of the different components of the vehicle.

I recommend this book to anyone who is soft skin armor enthusiast. I would like to thank MMD-Squadron and IPMS/USA for the opportunity to do the review on this book.
