Part one of the oppostion, the ones that did the actual fighting, well terrorists raids. The Sudetendeutsches Freikorps. A mixture of local ethnic Germans, the odd SA member. To maintain some level of plausible deniability of German involvement (good luck with that!) they were mostly equipped with small arms taken from Austria, Hitler having annexed Austria a feew months earlier. A mix of Empress Freikorps, Eureka and BTD partisans, Cannon Fodder revolutionaries plus various conversions of WG, etc, etc. There's even a BTD Boer in there.
