double digit Ukrainian airfields, C2 stations, S-300 anti-aircraft systems, radar stations... not impressed you? Or you just followed this war from propaganda? Maybe you should ask members of Ukraine foreign legion. They have the first hand personal experience and knowledge to tell you. A few of them are pretty active on social media.
Did I mention hypersonic missile? Russia has been working on scaling down their tactical nuclear weapons which is always their advantage, making them more practical.
