The Reichsarbeitsdienst (RAD, “Reich Labor Service”) was a major organization established by Nazi Germany as an agency to help mitigate the effects of unemployment on German economy, militarize the workforce and indoctrinate it with Nazi ideology.  It was the official state labor service, divided into separate sections for men and women.
