russia tried sending the muslims but they quickly got wise and negotiated "we won't march on moscow if you let us be the blocking troops that stay away from the front shooting retreating russians". after that it was mostly rural farmers because you can take 50% of a town of 200 and only need to put down a rebellion of 100. for the last year they have been recruiting from africa and north korea because they can't take many more from russia without the population coming for blood.
