An Arbeitsmann from the Schleswig-Holstein Arbeitsgau, 76. Arbeitsgruppe, 3. Abteilung, stands among the dunes of the German North Sea coast. He wears the brown uniform of the Reichsarbeitsdienst, the State Labor Service. Basing RAD on earlier labor organizations, the Nazis made service compulsory and nationwide. Every man aged 18 to 25 had to serve for six months before they were called up for army service. Before the war, the RAD was mostly deployed in agricultural and similar projects in Germany. While not a part of the Wehrmacht as such, once WW2 began, the RAD supported the army in many capacities, like building fortifications and airfields, laying minefields, repairing roads, loading and unloading supplies, etc, from Norway to the Mediterranian Sea. Later in the war they were even deployed as troops, but with minimal military training, they didn’t do well.
By organizing the RAD, the Nazi government achieved several goals. They got a useful workforce, the men got used to work as a unit (if they hadn’t been in the Hitlerjugend already), and they were subjected to more indoctrination. The RAD was another aspect of the totalitarian state.
