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.
Untersturmführer was the first commissioned SS officer rank, equivalent to a second lieutenant in other military organizations. The insignia consisted of a three silver pip collar patch with the shoulder boards of an army lieutenant. Because of the emphasis the SS placed on the leadership of their organization, obtaining the rank of Untersturmführer required a screening and training process different from the standard promotion system in the enlisted ranks.
In the early days of the SS, promotion to Untersturmführer was simply a matter of course as an SS member rose within the enlisted ranks to a position where they were ready to assume the duties of an officer. Untersturmführer was also occasionally an appointed position, given to an SS member so that they would be able to immediately begin as an officer in the organization. This was typically the case in security organizations, such as the Gestapo and Sicherheitsdienst (SD). A typical scenario in the early SS was for a member to join as an SS-Mann and then receive promotion directly to Sturmführer. In some cases, where an officer was being "groomed" to take up an SS leadership position, an officer could be promoted even higher. Such was the situation with Friedrich Jeckeln who was promoted directly from Mann to Sturmbannführer as well some situations of SS officers joining the organization as an SS-Oberführer.
