What is "weerbaarheidsafdeling"

The Weerbaarheidsafdeling (typically called WA) was the paramilitary arm of the National Socialist Movement in the Netherlands (Dutch: NSB), the fascist political party that collaborated with the German occupiers of the Netherlands during World War II. The organization, roughly equivalent to the German SA, was founded in 1932 by Anton Mussert, co-founder of the NSB in 1931 and its leader until the end of the war. Members marched in black uniforms and were thus called "blackshirts". In 1933 the Dutch government banned the wearing of uniforms and the WA was abandoned in 1935 to forestall the Dutch government from banning it completely. In 1940, after the German invasion, it was reinstated. They specialized in violent attacks particularly on the Dutch Jewish population.
