People seem to assume that Roehm would have literally abolished the Army and invaded countries with street thugs. I have a feeling he'd more likely take a page out of the Russian book, mass conscripts backed with elite political divisions and NSDAP Kommissars! Punishment battalions as well.
One effect would perhaps be a more sincere attempt to unite all Germans, ie Swiss and Tyrolians as well. Germany vs the Stresa Front!
If the Strasser brothers have major influence, sincere ties with the Soviet Union might be forged as well (they saw Nazi Germany and Soviet Russia as natural allies)
