The M1 helmet is a combat helmet that was used by the American military from World War II until it was succeeded by the PASGT helmet beginning in 1985. For over forty years, the M1 was standard issue for the U.S. military and naval forces, and has become an icon of the American military, with its design inspiring other militaries around the world.
Les Dillon was issued a M1 Helmet after the U.S. military updated its technology in preparation for the liberation of Hawaii in 1943. Dillon complained that his new helmet resembled a pot or a "footbath". He had worn the original M1917 for 25 years in military service and saw nothing wrong with it. Despite Dillon's misgivings, he soon discovered that the M1 covered more of the user's head.
When the Soviet Union invaded West Germany through Fulda, Gustav Hozzel and Max Bachman enlisted in the German Emergency Militia and were issued Springfield rifles along with uniforms and American style helmets. Hozzel thought the helmet didn't cover enough of his head but didn't fuss since it was better than nothing. After some hard fighting, Hozzel continued to hold that view but kept the American model after several other volunteers were killed for wearing Stahlhelms.
