The only sources I can find for that are all Russian. Wikipedia (Which I assume you will dismiss out of hand) says it's complicated to determine at best, as they both hide information and boost propaganda. At least don't state it as fact. No one actually knows, which is why citing sources is helpful so that weight can be added.
I mean I guess I disagree with the fact that it has any truth about being a "special military operation", when it is really an invasion where a country is trying to gain territory using ground forces etc. It's an invasion and a war, they wanted the binary outcome, they just didn't expect the opponent to push back so strongly.
