Mann was a paramilitary rank used by several Nazi Party
paramilitary organizations between 1925 and 1945. The rank is
most often associated with the SS, and also as a rank of the SA
where Mann was the lowest enlisted rank and was the equivalent
of a Private.  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.
