Nazi officers were high-ranking members of the German military and the National Socialist Party during the Third Reich, responsible for implementing the policies of Adolf Hitler and overseeing the machinery of the Holocaust. They played a critical role in orchestrating the genocide of six million Jews and millions of others deemed 'undesirable' by the Nazi regime, including Roma, disabled individuals, and political dissidents. Their actions were characterized by a strict adherence to Nazi ideology and an often brutal enforcement of orders.
