'Squad leader') was a title or rank used in early 20th century German military terminology.
In German, Schar was one term for the smallest sub-unit, equivalent to (for example) a "troop", "squad", or "section".
The term Scharführer can be traced to World War I, when it was referred to a NCO in charge of several shock troopers, or other special forces soldiers.
Scharführer was the first non-commissioned officer rank of the SA, and was denoted by a single pip centered on a collar patch.
[2] The rank of Scharführer was also used by other Nazi Party organizations; among them the National Socialist Flyers Corps (NSFK), National Socialist Motorist Corps (NSKK) and the Hitler Youth (HJ).
