The SD worked hand-in-hand with the Gestapo, although they had some overlapping authority and operations. The SD would perform intelligence gathering, surveillance and spy on members of the other Nazi Party organizations, military officers and the public at large. After the SD gathered information, the Gestapo would then arrest the person or people in question; both real and perceived political enemies of the Nazi state. Pursuant to German law passed in 1936, the Gestapo was given the power to arrest, interrogate and imprison people without any judicial review by the courts.

This was the military branch of the SS.<ref>Wegner (1990); McNab (2009)</ref> | The SD worked hand-in-hand with the Gestapo, although they had some overlapping authority and operations.
