In November 1935, the psychological war laboratory of the War Ministry submitted a study about how best to undermine Red Army morale should a German-Soviet war break out. Working closely with the émigré Russian Fascist Party based in Harbin, the German psychological warfare unit created a series of pamphlets written in Russian for distribution in the Soviet Union. Much of it was designed to play on Russian anti-Semitism, with one pamphlet calling the "Gentlemen commissars and party functionaries" a group of "mostly filthy Jews". The pamphlet ended with the call for "brother soldiers" of the Red Army to rise up and kill all of the "Jewish commissars".
