Wehrmacht Long Service Award
The Wehrmacht Long Service Award was a military service decoration of Nazi Germany issued for satisfactory completion of a given years of military service. Each branch of the Wehrmacht (Army, Navy, and Air Force) maintained their own version of the Long Service Award and the decoration was issued for 4, 12, 18, 25, and 40 Years of Service. Recipients of lower year awards would wear the decoration simultaneously with higher level decorations.
The Long Service Award was retroactive throughout a service member's career, encompassing Reichswehr service as well as service dating during and before World War I. As such, there were a handful of 40 year awards presented, even though the Third Reich itself existed for only twelve.
The Waffen-SS, considered an integral part of the German armed forces during World War II, maintained their own SS Long Service Award with similar award criteria to the standard military version.
