Pretty much, it won't even fall. Buildings destroyed, maybe hit Presidential Office and other Government buildings, then leave. I don't even have faith that Russians want to be fighting this war, as this is just pressure from Putin to get things down. Morale is at a all time low, and I always refer to what Cus D'Amato said to Tyson; a fight is 90% Mental and 10% Physical.
US is supplying intelligence, drones, secret ops... everything.
And Russian officers are telling their men to go out, kill civilians, and just advance... but not in a cautious one; they overstep the lines of where to advance and where to hold.
