They have plenty of artillery too, so they can gradually turn cities to rubble. But they simply don't have then power to occupy much territory with any real degree of control, except maybe in the east.
Yes, I agree on Finland, they just don't seem to have the resources or logistics to fight on two fronts like that. My comment was more with respect to Ukraine. You don't need pinpoint accuracy-- or much accuracy at all-- to gradually demolish the city. The ability hit the desired quadrant may suffice.
As Ukrainians push more resources towards the east Russia's problem might be that such artillery isn't quite mobile, there's no run-and-gun capability there, while weapons capable of taking them out are man-portable.
Despite that, I don't see a happy ending for the Ukrainians here. As much as Russia has already lost, they can't accept defeat in this without the power structure suffering what might be a deadly blow.
