So aside from switching conscripts to professional soldiers immediately prior to the invasion, Russians appear to be using cadets in Ukraine. This hasn't been confirmed anywhere else yet tho but would line up with horrible morale of Russian soldiers, reports of Russian soldiers begging for food, telling fleeing Ukrainians they didn't even want to be there, etc.
Wonder how long it'll before Russia puts out commissars and political officers to "up" morale.
