They failed to take Kiev, in spite of a serious effort, at the start (failed decapitation of the government) and lost 200 paratroopers as a result.
They retreated from the whole Northern region, with the loss of a significant amount of armored vehicles and casualties.
Those facts are not in doubt.
The Russians themselves showed footage of the attempted paratrooper takeover of the airport. (at the beginning)
The Russians admit the Moskva was sunk.
The exact number of Russian armored vehicles destroyed may not be known, but it is, at minimum a few hundred. Neither side gives out exact numbers of their destroyed equipment. There is plenty of misinformation on both sides; but separate images of 1500 destroyed armored vehicles is unlikely.
Maybe it is only 500; that is still significant.
If those are all "feints" and "victories", many more like them will lose the war.
