Polizeiregiment "Südtirol" (Police Regiment "South Tyrol"), later Bozen, and finally SS-Polizeiregiment "Bozen", was a military unit of the German Ordnungspolizei ("Order Police") recruited in the largely ethnic-German Alto Adige region in north-east Italy in late 1943, during the de facto German annexation of the region. The ranks were ethnically German Italian draftees while officers and NCOs were Germans. On 23 March 1944 the 11th company of its 3rd battalion was the target of the Via Rasella attack in Rome, that led to the bloody German retaliation known as the Ardeatine massacre.
