Certainly, the units in the field, even if they were thrown in as poorly trained soldiers and disorganized.... There's a very cruel learning process in war. Even inexperienced soldiers become savvy veterans after a certain amount of fighting if they survive. Otherwise, they don't survive.
Yes, I think we are seeing some operational improvements from what we saw in the initial days of the war. Russia has organized itself to provide more weapons and more personnel, and throw them into the war.
I think again back to information warfare. There has been an interesting change in the nature of internal Russian propaganda, which is basically informing the Russian people that this is an existential struggle for which they have to be prepared to make long-term sacrifices. That's the message.
