Aside maybe some individual reactions, the women of the Red Army and various Partisan groups in Europe were treaty harshly and brutally by the Germans. The general reaction can be summed up as shock and horror. Nazi propaganda treated the fact that women fought with the Red Army as a part of the horrors of Bolshevism, where even traditional gender roles were subverted by "communist barbarity".

Rather than reluctance, the general reaction was violence. Many a female Red Army soldier was shot using the Commissar's order and those who were captured were not treated as POWs but directly sent to the special camp for female soldiers in Auschwitz.

From what we can tell of surviving accounts of Wehrmacht members female soldiers were first viewed as a curiosity but quickly became an object of intense hatred. The "Flintenweiber" (shotgun dame) was seen on par with Communist Commissars and Jews.
