I’m not an expert but from my understanding the soviet’s tactics were quite a bit different from Ukraines.
The soviet’s continuously threw away lives to stop the German advance. Constant attacks tossing way soldiers lives but slowly degrading the German supplies and manpower. The Soviet’s also lost most of their industry early on in the war. Most of it was located in regions that Germany conquered quickly or their airpower wrecked in the early months of the war.
The only reason they were able to stop the German advance at all was because of the massive amount of goods and weapons supplied by England and the U.S.
Ukraine has set up heavily defended kill zones with multi-layered defenses. Russia’s continuous attacks are chewed up in theses zones. Eventually Russia degrades the defenses enough that Ukraine retreats to the next prepared zone and starts over fresh. Ukraine has slowly lost ground but Russias entire Soviet era stockpiles have been decimated with these tactics.

Tuapse was I believe the first time Ukraine went for the total destruction of the facilities. All the other hits have been at strategic targets that disabled key processes.
It’s sign of a massive shift in air superiority in favor of Ukraine.
