Yep. no doubt. Imposssible to quantify, but reports at the time were at least a million men fled to Georgia, Kazakhstan, etc.
I make no claim that the 575k number is dead. Even UA says that's their estimate of dead and wounded. And to be extremely generous, let's say 30-40% of those wounded are probably so disabled, amputees or worse, that not only can they not fight anymore, but they can't work jobs at their full pre-invasion potential. That would still be hundreds of thousands of lost labor force participants in a country who relies massively on heavy industry and resource extraction manned by able bodied, if often drunk, raw manpower. They won't be shifting war amputees to service sectors desk jobs and call centers.
These newly disabled veterans will become burdens on a state that probably won't honor the support agreements to their full extent, making them worse than simply unproductive - it will make them bitter living testaments to the stupidity of this war and it's broken promises. In the cold caclulus of Russian brutality - these people are better off dead telling no tales and drawing no pension than they would be alive. Russia's interal ethnic cleansing and useless mouth disposal of their own people sometimes gets lost in the ocean of wickedness that this entire war has been.
Yes, that's exactly it. Their most advanced weaponry is being made and used instantly, as opposed to being drawn down from older stockpiles. This is suggestive that those initial stockplies are gone, and that they're having to use things as fast as they can make them.
It paints a picture that they are struggling to keep up, that they're not capable of further quick escalation, and that they'd be very sensitive to a disruption in the delivery of components required to make these things when they're using them as fast as they can build them.
