The M1 helmet was introduced into service in 1941 for World War 2, replacing the earlier Brodie helmet that was worn during WW1 and the inter-war years. The M1 has a two-part construction, with an inner fiber liner which has the suspension, and an outer metal shell to protect against shrapnel. This design was based on football helmets of the 1930’s. The M1 helmet was used in American service from 1941 – 1986, when it was replaced with the Kevlar PASGT design. The helmet was also widely exported to and copied by western-aligned nations during the Cold War. [1]
