"The book looks at everything from pistols to flame throwers and from rifles to anti-tank guns . . . the package offers a lot of bang for your buck." —War History Online 
During the arduous campaigns in theatres of war from the Pacific to North West Europe, American infantry weapons played a key role in the eventual victory over the Axis forces. In so doing they earned a special reputation for ruggedness and reliability. In addition to being used by US ground forces they were widely adopted by other Allied nations.
Expert author Michael Green puts the full range of small arms, be they rifles, submachine guns, shotguns, pistols, machine guns as well as mortars, anti-tank weapons and close infantry support artillery under the microscope.
Many names such as the Browning Automatic Rifle (BAR) and the incomparable semi-automatic Garand will be well known whereas others (the Johnson Rifle and Reising SMG) are not. The typically informative text completes the wide range of photographic images.
"Standard US infantry weapons are depicted in the hands of the troops who used them operationally. This book is especially valuable to a wide readership—military historians, collectors, re-enactors, museum curators and authors. It would also provide inspiration for military modellers searching for realistic depictions of various figures." — Classic Arms and Militaria

Chapter One

Individual Infantry Weapons

The most widely used handgun in American military (i.e. the U.S. Army and U.S. Marine Corps) service during the Second World War was officially referred to as the Pistol, Automatic, Caliber .45 Model 1911A1. Most referred to it as the ‘.45’, the ‘.45 automatic’, or the ‘Colt .45’. It entered into production in 1926 and was an improved version of the original (or first generation) model of the weapon designated the Pistol, Automatic, Caliber Model 1911, employed during the First World War. As so many of the M1911s remained in the inventory, only a small number of the improved second generation A1 variant were built prior to the Second World War.

With America’s entry into the Second World War, following the Japanese attack on Pearl Harbor, Hawaii, and with the American military dramatically growing in size, the Colt Patent Firearms Company was contracted to build a large number of the M1911A1 version of the weapon. Because Colt could not construct the quantity asked for by the U.S. Army Ordnance Department (hereafter referred to as merely the Ordnance Department), four civilian firms were contracted by the Ordnance Department to build the weapon. The American military saw the M1911A1 primarily as a defensive weapon and sought to restrict its issue to officers, to some crew-served weapons, and rear area service troops.

A comparison between the M1911A1 and the various German military semiautomatic pistols comes from a U.S. Army report published in March 1945: ‘The standard caliber .45 U.S. automatic is preferred to any of the German-issue pistols. The greater striking power is desired over the advantage of a lightweight weapon. The safety features are considered superior to those of German pistols.’

U.S. Army Ordnance Department

The Ordnance Department was responsible for the design, procurement, distribution, and maintenance of all the U.S. Army’s weapons, and by default, the majority of weapons for the U.S. Marine Corps; although, prior to the Second World War, the U.S. Navy, which oversaw the U.S. Marine Corps, acquired some weapons that had not been adopted by the U.S. Army. When a new weapon passed all its acceptance tests it was standardized (accepted/adopted) by the Ordnance Department and ordered into full-scale production. The letter ‘M’ in a weapon’s designation indicated that it had been standardized.

The only other handgun to see service in any substantial way with the American military during the Second World War was .45 caliber Model 1917 double-action revolver. It was a leftover from the First World War and had been built by both Smith and Wesson and Colt during that conflict. Approximately 15,000 were pulled from storage in 1941 and refurbished before being reissued.

Bolt-Action Rifles

Another First World War era weapon that was updated for use during the Second World War was officially labeled the Rifle, Caliber .30, M1903. The bolt-action rifle had been developed prior to the First World War and was built by both the government-owned Springfield Armory and Rock Island Arsenal. The bolt-action system of operation for the weapon was a derivative of the German military Mauser rifle design.

The Rifle, Caliber .30, M1903 fired the M1906 cartridge commonly referred to as the .30-06 cartridge, which proved to be the standard American rifle and machine gun cartridge of both the First and Second World Wars. The rifle itself was best known to American infantrymen as the ‘Springfield 03’ or just the ‘03’ and earned a sterling reputation in both war and peacetime for its reliability and accuracy.

The post First World War replacement for the bolt-action M1903 was a semiautomatic rifle that began entering service with the U.S. Army in 1937, but initially in very small numbers. With the lead up to America’s official entry into the Second World War the Ordnance Department was forced to resume production of the bolt-action M1903 until production of the new semi-automatic rifle could be ramped up to sufficient levels to meet all its needs.

As the original government-owned facilities that had built the M1903 were busy with other projects prior to America’s official entry into the Second World War, the Ordnance Department contracted with the Remington Arms Company to begin production of an identical copy of the First World War era M1903. To speed up the number of rifles built by Remington, the Ordnance Department, together with engineers from the firm, simplified the weapon design, resulting in a new model designated the Rifle, Caliber .30, M1903 (Modified).

Not long after the M1903 (Modified) came about, Remington engineers made some additional modifications to the weapon’s design to further speed up the production of the rifle. This resulted in the final version of the weapon designated the Rifle, Caliber .30, Model M1903A3.

To increase the number of M1903A3 rifles being built, the Ordnance Department contracted with the Smith-Corona Typewriter Company to build the weapon. Production of the M1903A3 was canceled in early 1944 by the Ordnance Department as a sufficient number of the new semi-automatic rifles were now in service.

M1903 Sniper Rifles

There was a dedicated sniper version of the M1903A3 labeled the Rifle, Caliber .30, M1903A4 (Sniper’s). The U.S. Army’s table of organization (TO&E), during the Second World War, called for one sniper rifle per platoon, although their popularity sometimes found them at the squad level, as seen in this passage from a U.S. Army publication labeled Combat Lessons No. 5: ‘We had one Springfield 03 Sniper’s rifle with scope with each squad. It is absolutely accurate. All the fellows want one. It is not too bulky and can be carried just as easily with as without scope.’

Not happy with the Rifle, Caliber .30, M1903A4 (Sniper’s), the U.S. Marine Corps modified some of its pre-Second World War M1903A1 rifles into makeshift sniper rifles during the conflict. The M1903A1 had been standardized in 1926 and differed from the M1903, as it had a pistol grip type stock. The M1903A1s would be fitted with scopes designed and built by the civilian firm of the John Unertl Company and issued in 1942 and 1943.

Pulled from Storage

In addition to the various models of the M1903 brought back into service during the Second World War, the Ordnance Department reached back into its storage warehouses before America’s official entry into the conflict and pulled out another First World War era bolt-action rifle labeled the Rifle, Caliber .30, Model of 1917 (Enfield). It was an American-built copy of the British designed and built bolt-action rifle designated as the Short Magazine Lee-Enfield Rifle No. 1, Mark III.

The American model of the Enfield differed from the British Army model, as it fired a .30-06 cartridge rather than the British Army .303 cartridge. Other than a brief appearance with U.S. Army units fighting in North Africa in November 1942, the American version of the Enfield was reserved strictly for stateside training duties and was often the first weapon American soldiers trained on during the early years of the conflict.

Semi-Automatic Rifles

The eventual replacement for the M1903 rifle for the U.S. Army was the Rifle, Caliber .30, M1, a semi-automatic w...
