Police Regiment Bohemia was created shortly after the occupation of Czechoslovakia in March 1939. Assigned were six battalions numbered I through VI, although they were renumbered in the 200 series in October. Some of these were transferred elsewhere and only partially replaced so that the regiment had five battalions in early 1941, Police Battalions ("Polizei-Batallion") 32, 316, 317, 319, and 320. All of these units were transferred to Russia after Operation Barbarossa in June and gradually replaced by three newly formed battalions, Reserve Police Battalion Prague, Reserve Police Battalion Kolin, and Reserve Police Battalion Klattau. When the regiment was renamed in July 1942, the battalions were redesignated as the regiment's first through third battalions, respectively, although their headquarters companies were not formed until 23 January 1943. All of the police regiments were redesignated as SS police units on 24 February. In April, I Battalion became part of Police Rifle Regiment 33 ("Polizei-Schützen-Regiment") and was later replaced by Police Training Battalion Klagenfurt and Graz. In October it became independent and was sent to Italy. II Battalion was transferred to Hungary in March 1944 and was redesignated as II Battalion of the 1st SS Police Regiment in August.
