Obersturmbannführer Bruno Müller or Brunon Müller-Altenau (Strasbourg, September 13, 1905 – March 1, 1960, Oldenburg) served as Senior Storm Unit Leader during the Nazi German invasion of Poland. In September 1939, he was put in charge of the Einsatzkommando 2/I attached to Einsatzgruppe I of the Security Police. They were deployed in Poland along with the 14th Army of the Wehrmacht. Little is written about Müller's life before that, although his wartime career is fairly well documented.
