 But it is common to use different kind of identification markings on the helmets.As fire service is mainly organized by the different federal states and in the end is the responsibility of the different communities, there is no standard kind of identification markings for helmets.In Bavaria for example the "Kommandant" (elected fire chief) is marked with a red vertical stripe on the helmet and the “Gruppenführer” (group leaders) with thin black rubber bands around the helmets.
