Beginning in September 1941, the SS and police command created four Infantry Defence Battalions (No. 37-40) and a reserve and sapper battalion (No. 41-42), which were operationally subordinate to the Wermacht. From 1943 they were called Police Battalions, with 3,000 serving in them. In 1944 they were transformed into two infantry battalions and evacuated to Germany in the fall of 1944, where they were incorporated into the 20th Waffen-SS Division.
