I get your point. However, within a military it’s not like you’re stationed where you are originally from. So, most military left right now are the minorities from the east, or at least, they are drafted and sent to the front an mass. Except maybe for the officers not going to the front. But then again, they aren’t stationed where they are from, but where the regime requires them to be. I bet the minorities living in Russia close to Finland won’t feel much support for the regime, unless they too are too much brainwashed by the propaganda. But in general, the minorities often prefer to separate from Russia completely.
