In WWII the Germans formed Police Battalions from local forces in occupied areas.
As police forces these units were usually given odd mixtures of rifles, pistols, and submachine guns.
The both worked to round up enemies of the occupiers and to fight partisans.

These troops were often very hard core and did not hesitate to apply the strongest measure if they met resistance.
These troops usually operated in conjunction with German units.
Some of their methods were judged to be very harsh, even by standards of the never squeamish SS.
Still, this is a good set to have on anti-partisan duty to free up regular troops for normal combat.
