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 color
