As I understand it, Russia hasn't been able to actually call it a "war" domestically, they did burn through prisoners rather than trained forces until they ran out of people willing to believe the chances of surviving to enjoy early release, and Russian forces have been only partially rather than fully mobilised with their conscripts mostly kept back from the front line for a while now due to domestic concerns.
