Which were probably even less combat worthy than active formations. And I somehow doubt the other formations (excluding Reichswehr and police) had no reserves. The Schufos for example are only the elite formations of the Reichsbanner, they were supported by the less trained (SA level) Stafos and the youth organisation Jungbanner. I simply don´t see a possible victory of Röhm even if he is willing to risk a drawn out civil war. The numbers favour him not really: Lets take the fall of 33: 2 million SA men (taking your numbers) against 100,000 soldiers, 500,000 Stahlhelm men, 250,000 Reichsbanner elite men supported by the rest of this former 3 million members organisation and the SS with another 204,000 men.
