 Much of the intent of organizing these police units was to band together groups of men who had military training and knowledge stemming from their First World War experience.Designated the SA Field Police (SA-Feldjägerkorps), this formation was organized into eight battalions of approximately 195 men each with each battalion being assigned to a specific city or district with its headquarters in Berlin.Members of the SA-Feldjägerkorps were allowed to rejoin or transfer into the SS following completion of their service with the unit.
