During World War II, the U.S. military used a number of different helmets. One of the most famous helmet designs from World War II is the M1 helmet, which was introduced in 1941 and used by U.S. forces throughout the war. The M1 helmet was made of steel and had a liner that could be adjusted to fit the wearer’s head. It provided good protection against shrapnel and other debris, and it was widely used by U.S. infantry and other ground troops during the war.
In addition to the M1 helmet, the U.S. military also used other helmet designs, including the M2 helmet, which was similar to the M1 helmet but had a slightly different shape, and the M3 helmet, which was made of fiberglass and had a more modern design. These helmets were used by various branches of the U.S. military, including the army, navy, and air force.
