Therefore, the M1917 model was considered suitable for protecting the top of the head and by removing its brim, by adding sidepieces and rearpieces, and by incorporating the suspension system into a separate inner liner, the World War II Army helmet came into being.The original test item was known as the TS3, and it received a favorable report from the Infantry Board in February 1941. 305) was standardized on 30 April 1941 and was approved on 9 June 1941.During the period from August 1941 to August 1945, 22,363,015 M1 helmets were produced.
The ballistics properties of the outer shell had been improved so that it would resist penetration by a 230-grain caliber .45 bullet with a velocity of 800 f.p.s. 305C) used in football helmets was modified for the inner liner. During the course of the North African campaigns in 1943, the rigid hook fastener of the chinstrap was found to be a source of potential danger by remaining intact under the impact of a blast wave resulting from a nearby detonation and thereby jerking the head sharply and violently with the production of fractures or dislocations of the cervical vertebras.
The principle of the original Riddell suspension did not contain an adjustable headband, and this feature was developed for the helmet liner. Therefore, it was necessary to redesign the helmet strap with a ball-and-clevis release so that it would remain closed during normal combat activities but would allow for.
However, it is felt that there has been an intimate association and liaison between all of the interested technical services and that the inclusion of this chapter in the present volume follows a natural and logical selection of materials. The British helmet had twice the ballistic strength of the French helmet.
(4) Helmets and Body Armor, Office of the Chief of Ordnance, Washington, 1 June 1945. 44 Relating to Helmets and Body Armor, 1917-August 1945, Ordnance Department, Washington, D. Therefore, in many ways, the relating of the development of helmets and personnel body armor would seem to be more of a history of the participation of the Quartermaster Corps and the Ordnance Department rather than the Army Medical Service. The helmet was made of 13 percent pressed manganese steel alloy, 0.035 inch thick, and could be ruptured only by a blow of 1,600 pounds or more.
This problem had its origin, in good part, from the type of ballistic test in practice at the time the helmet was being developed. Side view, showing increased coverage to sides and back of head. However, battle casualty survey studies during World Wars I and II and the Korean War have shown that the primary wounding agent among the WIA and the KIA casualties was the fragmentation-type weapon.
The caliber .45 pistol ball was the major test weapon, and this type of projectile with its soft lead core and thin gliding-metal jacket will deform easily against the Hadfield steel. The World War II experiences are universal except for the surveys of some of the Pacific island campaigns where small arms missiles accounted for a greater proportion of casualties.Following a series of experimental models (the model 5A was of pot-shaped design and received extensive testing before it was discontinued in 1932) and tests, it was recommended in 1934 that the M1917 helmet with a modified lining of a hair-filled pad be standardized as Helmet, M1917A1 (fig. The final end item with an adjustable headpad weighed 2 pounds and 6 ounces.A lull in helmet development occurred in the period from 1934 to 1940 when the first draft call was issued.General Adrian of the French Army noted that a soldier who had received a head wound due to a rifle bullet explained his escape from death on the fact that he had carried his metal food bowl under his cloth cap. Numerous experimental models were developed to provide (1) additional protective coverage; (2) improved ballistic properties; (3) adaptability for special functions, such as machinegunner, tank operator, aviator, and so forth; (4) a more adequate suspension lining; and (5) a distinctive patriotic design.Therefore, following initial experiments in 1914, steel cap liners ("casque Adrian") were issued to French troops in 1915 and led to the characteristic World War I French helmet in 1916. Because of the large numbers of helmets of the M1917 design which were produced in the United States, none of the experimental models developed by the U. Army Ordnance Department received adoption before the end of World War I. 642 Following the decision in 1917 to equip the American Expeditionary Forces with a helmet, 400,000 helmets were initially procured through the British Quartermaster's Department.
