When [Friedrich] Krohn and Hitler first met around the time that Hitler first attended a meeting of what was to become the Nazi Party, Hitler told hi… - Thomas Weber

In theory, all Munich-based military units and thus Hitler’s regiment, too, were part of the Red Army. In that sense, Hitler served in the Red Army. In reality, however, most regiments neither actively supported the Soviet regime nor opposed it.

On May 3, 1919, 6 months after the revolution, Hitler said he was in favor of majoritarian democracy at a meeting of members of the 2nd Infantry Regiment in the regimental canteen on Oberwiesenfeld. The testimony states that the meeting had been called to discuss who should become the new commander of the regiment, adding that Hitler identified himself 'as a supporter of Social Democracy [Mehrheitssozialdemokratie; i.e. the SPD], albeit with some reservations.'

Even two days after the Soviet Republic had been proclaimed, Hitler stood for election again, when the new regime conducted an election among Munich's soldier councils to ensure support for the Soviet Republic by Munich's military units. Hitler was now elected Deputy Battalion Representative and remained in the post for the entire lifespan of the Soviet Republic.
