The Danish National Labour Service
On these pages I will go through the background and present a description of what the Danish National Labour Service was.
The photo above shows a LAT uniform, a DNSAP Agersted uniform, and the NSU symbol.
If you want to learn more about this specific area, I refer you to various books written by, among others, John T. Lauritzen.
Likewise, I am aware that a scholarly historical work on the DNSAP in North Jutland is currently being prepared, based on the Agersted party branch. Publication date unknown.
There are few sources available on ranks within the labour service; here is a draft of a rank structure with distinguishing marks.
