outbreak of World War II, the helmets became the subject of anti-Irish propaganda in Britain. A large number of the withdrawn helmets were reissued to various emergency services after being painted white. Switzerland used a helmet, designated the M1918, that was roughly similar to the M1916 but had a shallower, wider and more rounded crown and skirt. This was to protect against the harsh winter winds of the alpine regions. The Chilean Army was a prolific user of the Vulkanfiber models, bought before the Second World War, along with a few M1935 and Czechoslovak M32 helmets. After the war, local production of lightweight fiber and plastic models started, which are still in ceremonial & garrison use today. Small runs of steel helmets were made by FAMAE in the 80's, but ultimately were not adopted due to the ascendance of kevlar and synthetic ballistic fiber helmets by that time. A Stahlhelm with crossed bayonets and the corresponding number is the standard insignia of infantry regiments. During World War II, the Argentine Army adopted a similar model made of pressed fibre. For combat and provincial police use, imported Swiss M1918 Helmets were still in service as late as 1976. In the Socialist Federal Republic of Yugoslavia, due to large quantities captured by World War II Partisans, the Stahlhelm was used in Yugoslav People's Army up to 1959, when it was phased out and replaced by the M59/85 steel helmet. Postwar After World War II, West Germany's Bundesgrenzschutz border guards and some West German police units kept the Stahlhelm in their inventories (police units can be seen wearing them during footage of the Black September hostage crisis in 1972), and the Fallschirmjäger variant was used for some time by the GSG 9. With the re-armament of West Germany the Bundeswehr introduced the United States Army M1 Helmet which was replaced by a Kevlar helmet (Gefechtshelm), similar to the modern US helmets, in the 1990s. German firefighter units today still use Stahlhelm-shaped helmets in a fluorescent colour. East Germany's National People's Army M-56 helmet was modelled on an unused 1942 German design with a more conical shape. The Chilean Army still uses the Stahlhelm design for ceremonial purposes, as does the Bolivian Army. There are also some Japanese bicycle helmets (with accompanying goggles) that resemble the Stahlhelm. Many schools and universities in Mexico such as the Autonomous University of Baja California have military bands
