Stahlhelm (plural, Stahlhelme) is German for "steel helmet". The Imperial German Army began to replace the traditional boiled-leather Pickelhaube (spiked combat helmet) with the Stahlhelm during World War I in 1916. The term Stahlhelm refers both to a generic steel helmet, and more specifically to the distinctive (and iconic) German design.
The Stahlhelm, with its distinctive "coal scuttle" shape, was an instantly recognizable icon for military imagery and became a common element of military propaganda on both sides, just like the Pickelhaube before it.
When Gustav Hozzel joined the German Emergency Militia at the outbreak of World War III, he was issued an American styled helmet. He disliked it since it didn't cover as much of his head as the WehrmachtStahlhelm but kept it after the Soviets killed in cold blood a few Stahlhelm-wearing militiamen and left swastika placards by the bodies.
Despite its negative connotations, the efficiency of the Stahlhelm, and a shortage of other options, ensured that the design remained common on the heads of native collaborationist police in occupied Germany.
Bruce Delgado, commander of the Chatsworth Lancers, wore an old World War IIWehrmacht helmet (his grandfather's battle trophy) as part of his homemade battle dress. He had carefully sanded off the swastika since he did not want to send the wrong message about the Lancers.
