Berchtold changed the title of the office position, which became known as the Reichsführer-SS.[14] Schreck remained on the SS rolls as an SS-Führer and worked as Hitler's private chauffeur after Maurice until 1934.[15] In 1930, after the SS had begun to expand under Heinrich Himmler, Schreck was appointed an SS-Standartenführer, but had little actual power. He continued to serve at Hitler's side and they were on very good terms.[15]
