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. … - Thomas Weber

Hitler’s undetermined political future becomes even less surprising if we bear in mind that the intellectual origins of Fascism share central tenets with the non-Marxist Left. According to one argument, despite its eventual collision with the conservative Right once Fascism tried to come to power, early Fascism had been in its promise, rather than in its eventual application, more socialist than capitalist, more plebeian than bourgeois.

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 him that he favored a ‘socialism’ that took the form of a ‘national Social Democracy’ that was loyal to the state, not dissimilar to that of Scandinavia, England, and prewar Bavaria.

Hitler was picked as the representative of the men in his company. He now held a position that existed to serve, support, and sustain the left-wing revolutionary regime. Hitler’s task was to help facilitate the smooth running of the regiment. If we can believe an article published in March 1923 in the Münchener Post—a partisan Social Democratic newspaper but one that was generally well informed about the nascent National Socialist movement—his responsibilities eventually went further than that. According to the article, he also acted as a go-between with the propaganda department of this regiment and the revolutionary regime. The article claimed that Hitler took an active role in the work of the department, giving talks and made the case for the republic.
