Estonian Auxiliary Police

Estonian Auxiliary Police (Estonian: Eesti kaitsepataljonid, Eesti politseipataljonid, German: Estnische Hilfspolizei) were Estonian police units that collaborated with Nazi Germany during World War II. == Formation == Estonian units were first established on 25 August 1941, when under the order of Field Marshal Wilhelm Ritter von Leeb, commander of the Army Group North, Baltic states citizens were permitted to be recruited into Wehrmacht service and grouped into volunteer battalions for security duties. In this context, General Georg von Küchler, commander of the 18th Army, formed six Estonian volunteer guard units (Estnische Sicherungsgruppe, Eesti julgestusgrupp; numbered 181–186) on the basis of the Omakaitse squads (with its members contracted for one year).
