Further attrition is seen with those unwilling to fight and further practical attrition those effective to fight (18-30 in good shape vs. out of shape 30-60 yr olds). Then the in-shape willing to fight have to have support and training and logistics and pay and food and weapons and ammo so Russia in effect is down to a skeleton crew of demoralized poorly equipped lunatics (who believe everything they are told) with poor or absent leadership. Untenable.
