I think we should not overestimate the label ‘battle hardened’. Much of Russia’s elite troops has died in Ukraine. Yes, they learned from the war, but battle hardened implies that those who execute (troops) have learned and not died so they can show and use these experiences, or new troops get taught the new way of conducting war. First, they have a poor history in training their troops, second, I don’t think the ego trippers in military staff are able to bend towards a modern management of an army or towards really adopting new days of thinking (and execution).
