What is "untersturmfuhrer"

Untersturmführer was a paramilitary rank of the German Schutzstaffel (SS) first created in July 1934. The rank can trace its origins to the older SA rank of Sturmführer which had existed since the founding of the SA in 1921. The rank of Untersturmführer was senior to Hauptscharführer (or Sturmscharführer in the Waffen-SS) and junior to the rank of Obersturmführer.
