In 1938, with the rise of the SS-Verfügungstruppe (later called the Waffen-SS), the SS changed the rank of Mann to Schütze, although still retained the original SS rank of Mann for the Allgemeine-SS (General SS). The rank of Mann was junior to SS-Obermann.
In most Nazi Party organizations, the rank of Mann held no distinctive insignia. Some groups, however, granted a minor form of rank insignia such as a blank collar patch or bare shoulder board to denote the rank of Mann. An even lower rank, known as Anwärter, was established in the mid-1930s as a recruit or candidate position, held by an individual seeking an appointment as a Mann in a Nazi Party paramilitary organization.
