estonian officers and men in other units that fell under the conscription proclamation and had returned to estonia had their rank prefix changed from "ss" to "waffen" ("hauptscharführer" would be referred to as a "waffen-hauptscharführer" rather than "ss-hauptscharführer"). since the wearing of ss runes on the collar was forbidden by augsberger on 21 april 1943, these formations wore national insignia instead.
