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.
From June 1935 onwards, men aged between 18 and 25 had to serve six months before their military service. During World War II compulsory service also included young women and the RAD developed to an auxiliary formation which provided support for the Wehrmacht armed forces. (Wiki)

A little history of G. Brehmer:
The company of Gustav Brehmer was founded in 1871 in the town of Markneukirchen
in Saxony and became one of the premier manufacturers of war badges during the Third
Reich. Interestingly, Karl Wurster, owner of another major war badge manufacturer
during the Third Reich began his career working for Brehmer until he eventually opened
his own factory some 100 meters from Brehmer after leaving in 1912. The craftsmen at
Brehmer produced some of the highest quality badges for the Luftwaffe and Heer
including the numbered Panzer Assault Badge (PAB) and numbered General Assault
Badge (GAB), but was perhaps most well-known for their stunning Luftwaffe Flak
Badges. Until recently it was not known that Brehmer also produced a Heeres-Flak
Badge for the German Army. (Garlasko)
