English: Uniform of the SS-Totenkopfverbände, a branch of SS, a paramilitary organization of the Nazi Party NSDAP:

• Visor cap (German: Schirmmütze) with SS skull-and-cross-bones insignia (Totenkopf) and Nazi style national eagle-and-swastika device (Hoheitszeichen, Hoheitsadler, Reichsadler, Mützenadler).
• Death's head emblem and SS rank insignia (SS-Scharführer) on collar patches.
• The SA Sports Badge (SA-Sportabzeichen) on the left breast pocket of the tunic is upside down.

SS-Totenkopfverbände (SS-TV; literally "Death's Head Units") was the SS organization responsible for administering the Nazi concentration camps and extermination camps for Nazi Germany, among similar duties. While the Totenkopf (skull) was the universal cap badge of the SS, the SS-TV also wore the Death's Head insignia on the right collar tab to distinguish itself from other Nazi Schutzstaffel (SS) formations.
