Wehrmacht in Denmark. The original comment with this pin was: "Nazi soldiers in Holland". I'm 100 % sure this isn't Holland. The windmill on the pin is typical for Denmark. It's a windmill based on the Poul la Cours design . Poul la Cours was a Danisch windmill pioneer.
Waffen SS during the fighting in France, summer 1940. Platoon leader gives instructions. Note the young rifleman standing at attention while listening -- typical reaction inculcated into every Waffen SS man by fierce training. The platoon leader is armed with an MP40 SMG.
