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.'

On April 12, 1919, Ernst Schmidt decided it was time to leave the army. His friend Hitler, by contrast, chose to stay. This was an active decision on the part of the future right-wing dictator of Germany to serve a regime that at the time pledged allegiance to Moscow.
