Original Vietnam War M-1 U.S. Helmet with Original Camo Cover / Liner
The M1 helmet is a combat helmet that was used by the U.S. military from World War II until 1985, when it was succeeded by the PASGT helmet. The M1 helmet has become an icon of the US military, with its design inspiring other militaries around the world.
* Development of the M-1 Helmet *
At the entry of the United States into World War I, the US military was without a combat helmet; initially US troops arriving in Europe were issued with British Mk I Brodie helmets (those integrated with French units were given French M15 Adrian helmets). The United States quickly commenced manufacture of a version of the Mk I, designated the M1917, producing some 2,700,000 by the end of hostilities. At that point, the shortcomings of the M1917, which lacked balance and protection of the head from lateral fire, resulted in a project to produce a better helmet which would also have a distinctively American appearance. Between 1919 and 1920, a number of new designs of helmets were tested by the Infantry Board in comparative trials with the M1917 and helmets of other armies. One of those designs, the Helmet Number 5A, was selected for further study. This was an improved version of the Helmet Number 5, developed in 1917 and 1918 by Bashford Dean, the curator of arms and armor at the Metropolitan Museum of Art, which had been rejected during the war because of its supposed resemblance to the German stahlhelm. Eventually, tests held at Fort Benning between 1924 and 1926 showed that although the 5A offered better side protection than the M1917, it was more easily penetrated from above and in some circumstances, could interfere with firing a rifle.
* The Vietnam War *
The Vietnam War, also known as the Second Indochina War, and in Vietnam as the Resistance War Against America or simply the American War, was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. North Vietnam was supported by the Soviet Union, China, and other communist allies; South Vietnam was supported by the United States, South Korea, the Philippines, Australia, Thailand, and other anti-communist allies. The war, considered a Cold War-era proxy war by some, lasted 19 years, with direct U.S. involvement ending in 1973, and included the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist in 1975.
