I've seen a few mentions of attack on the power but nothing very significant. Considering all I read about was Russia saving missiles up for winter there hasn't been much at all.
The Su-34 is Russia's best plane when it comes to avoiding being shot down by an incoming missile (and if it's specs are to be believed, as good or better at it than anything NATO have), in theory it's rear facing radar should have picked up the incoming missile and allowed the pilot to fire one or more AA missiles to intercept it, if that failed countermeasures should have been launched and finally it's ECM should have protected it.
for the other when things were starting to get move in the few days before the invasion began there was loads of footage of even the top tier Russian units where for instance only about 1/3rd of the T-80 tanks in a column had full kit and 2/3rds were missing stuff like pintle or coax mounted equipment, etc. possibly some of that would be fitted at final staging areas but I suspect in a lot of cases it wasn't. Wouldn't surprise me if more of the Russian planes than not are flying without the full package.
Not yet, Russia did launch a Khinzel missile at Kyiv a few days ago but it got shot down along with a bunch drones. Whilst they don't have enough Patriots to cover every square mile from ballistics missiles there not the biggest threat. Ukraine is far more prepared to deal with the missile strikes this year then 12 months ago, last year they were using up S300 missiles on Kalibr cruise missiles and often has to use AK's to shoot down drones.
