Oskar Dirlewanger
Oskar Paul Dirlewanger (26 September 1895 – c. 7 June 1945) was a German military officer and war criminal. He commanded the Dirlewanger Brigade, a penal military unit of the Waffen-SS which served in World War II. Dirlewanger's unit is often considered the most notorious Waffen-SS unit, committing some of the conflict's worst atrocities, with Dirlewanger himself regarded as perhaps Nazi Germany's "most extreme executioner", engaging in frequent acts of violence, rape, and murder.
