The Netherlands had a korps policetroops aswell asside from the normal military police (marechausee), they were used to police the army, aswell as the areas under millitary command.
But they also had combat duties, like guarding the east outer defense lines in 1940, aswell as bridges. In this cappacity they would man bunkers armed with AT guns and heavy machine guns. They would be there next to the normal army personel.
The picture above is a foto of a Brandenburg command dressed in Dutch policetroop uniforms of wich a number was dispatched to capture vital bridges in may 1940 over the meuse and rhine rivers.
One or two succeeded, others were repulsed in dramatic hand to hand combat, others failed to materialise due to the team members being to drunk to show up.
I remember one quote of a border guard from a book as follows. "His helmet appeared to be made out of papermachee, when i hit him on his helmet with my klewang (Indian army sword) it went through everything."
