The absence of Russia's Air Force has been a bit of a mystery. Generally speaking, I think they will have a higher level of intellect - perhaps they are passively resisting the utterly ridiculous propoganda that "the Nazis are coming for us" and..."please launch your cruise missile at Ukranian cities to kill all the Nazis" b*******". Anybody with half a brain would realise they're being asked to commit unjustifiable war crimes and will be held to account.
The RuAF has certainly been in action against civilian targets. Many of the cruise missiles and other weapons are air launched. It is plausible that some of the pilots were unaware of the targets but:
