not sure this is realistic

million people get together? you need some kind of leadership. this mean u have someone u can aim your snipers at / throw KGB at to disappear into a gulag and never be seen again...

russia is not exactly usa where you are free to buy assault rifles in grocery store, or where you can buy even a small gun for that matter... its not like bunch of guys decide to storm Kremlin over the weekend and magically overthrow the gov

I mean it happened in russia in the past, but it was literally at a cost of several millions dead, not sure if this is the right solution
