Between 1925 and 1929, it became common for Nazis to wear makeshift paramilitary uniforms at Party rallies and during this time the SA expanded its own system of insignia as did the fledgling SS (Schutzstaffel), which had begun to appear as a force within the Party. As the Nazis gained more support throughout Germany, and moved outward from their power base in Munich, regional Nazi cells began to appear in such major cities as Stuttgart, Berlin, and Heidelberg. These "local Nazis" often adopted their own uniforms and titles with little standardization from the main Nazis operated out of Munich.
