Charles C. Roberts, Jr. has a bachelor’s degree, Masters degree, and PhD in engineering. He is the founder of Roberts Armory WWII Museum displaying artifacts from World War II including tanks, armored cars, halftracks, cannons, soft skinned vehicles, and military personnel equipment including several 37mm guns. He served in the U.S. Army from 1968–1970 as an engineer, designing and testing tanks, cannons, and aircraft. He is an expert on World War II military history and equipment, having authored several books on World War II history including Armoured Strike Force, The Boat that Won the War and U.S. Airborne Tanks 1939–1945.

This hard cover is the latest volume in the Casemate Illustrated Specials. The Cover upper color photograph is an American M3A1 37-mm gun on a M4 carriage. Note the muzzle gas deflector that was not used in battle in World War II due to munitions interference. I counted 220 black and white photographs / drawings and 79 color photographs, / illustrations. Many of the drawings and illustrations are from manuals.

The 37-mm gun origins go back to 1862 and the Lieber Code on how to conduct war. The Lieber Code was further developed at the1868 St Petersburg Declaration and then the 1899 Hague Convention. Their focus was how deadly an explosive shell could be by trying to limit the size of weapons. Think along the lines that is ok to have a bullet that kills a soldier, but not one that kills the soldier in a ‘mean’ way. The French developed the Model 1916 37-mm gun in World War I that also happened to be used by US forces as well. Post World War I saw the Swedish Bofors 37-mm anti-tank gun become prevalent [Page 012], and later the German PaK 37-mm anti-tank gun. The Spanish Civil War finally caught the US Army’s attention, and the secured two PaK 37-mm anti-tank guns as a basis to develop a US version. This development produced the M3 37-mm anti-tank gun that began manufacture in 1940 that would serve US forces in World War II. The sections include:

I really enjoyed the broad coverage in Charles C. Roberts Jr’s book. After providing coverage of the history of the 37-mm antitank gun, Roberts provides detailed drawings and photographs of the US 37-mm gun designs in Chapter 2. Page 39 provides sharp color photographs from Roberts’ collection. The first three illustrate the loading of a 37-mm cartridge into the breech of a M4A1 gun. The last photograph shows off the closed breech of a M3 gun. Roberts introduces the variety of 37-mm ammunition in Chapter 3. A good example is on Page 71 that describes the M54 with Tracer Fixed Hight Explosive Cartridge. The upper right drawing highlights the M56 Point-Detonating Fuse with the lower four drawings showing the M54 HE Cartridge. Chapters 4 and 5 describes all the vehicles, aircraft, and vessels that utilized the 37-mm gun. Page 091 shows off the LVT-(A)1 that carried the M5 tank turret to add firepower over machine guns. The two Appendices are filled with detailed drawings of the M3 and M4 Carriages along with ballistic charts. Page 152 depicts Penetration – Velocity Curves through armor plate based on Angle of incidence.

Modelers will have no problem finding kits of the M3 Antitank Gun with offerings in 1/87, 1/72, 1/48, 1/35, 1/24, and 1/6 scales. If you are interested in the 37-mm antitank gun, this is an essential volume for both the military historian and the scale modeler.

My thanks to Casemate and IPMS/USA for the chance to review this great book.

Highly recommended!
