In June 1940, Kaltenbrunner was appointed Police President of Vienna and held that additional post for a year. In July 1940, he was commissioned as a SS-"Untersturmführer" in the Waffen-SS Reserve. Throughout his many duties, Kaltenbrunner also developed an impressive intelligence network across Austria moving southeastwards, which eventually brought him to Himmler's attention for the assignment as chief of the RSHA in January 1943. The RSHA was composed of the SiPo ("Sicherheitspolizei"; the combined forces of the Gestapo and Kripo) along with the SD ("Sicherheitsdienst", Security Service). He replaced Heydrich, who was assassinated in June 1942. Kaltenbrunner held this position until the end of the war. Hardly anyone knew Kaltenbrunner and upon his appointment, Himmler transferred responsibility for both SS personnel and economics from the RSHA to the SS Main Economic and Administrative Office. Nonetheless, he was promoted to SS-"Obergruppenführer und General der Polizei" on 21 June 1943. He also replaced Heydrich as President of the International Criminal Police Commission (ICPC), the organization today known as Interpol.
