I am having the hardest time finding resources on this topic. I was wondering if the indigenous tribe people were somehow drafted into the Red Army, specifically the tribes that were in the far eastern part of Asiatic Russia. If so, how were the Soviets able to maintain such control over such vastly different cultures? And how did the tribesmen do in combat?
Part of the problem you may be encountering is that the term "indigenous" was apparently not even applied in Russian law prior to 1993; the USSR claimed to have no indigenous peoples as such (Anna Stammler-Gossmann, "Who is Indigenous? Construction of ‘Indigenousness’ in Russian Legislation," International Community Law 11, no.1). So that kind of designation probably wouldn't have factored into conscription or enlistment records.
Short of regional extrapolation from the Red Army Archive, or extrapolation on other basis, it's possible numbers just aren't able to be generated on this front; any indigenous people who did wind up serving in the army would likely have been assimilated into Soviet culture, which is to say, they wouldn't have been numerous enough to exactly rebel very hard against Soviet "control" were they in fact conscripted.
IF these peoples were still primarily nomadic during this time, though, it seems possible they were able to evade most Soviet 'outreach' well into the twentieth century. (Evenki, one of the most populous indigenous Russian peoples, were indeed still nomadic into the 1920s, as were the Chukchi. See Geoffrey A. Hosking, "Rulers and Victims: The Russians in the Soviet Union.")
