According to who? The Ukrainians. They honor neo-Nazis and use them as frontline fighters. Zelensky has imprisoned opposition leaders, shutdown ALL opposition parties and banned opposition media outlets. They made up the "ghost of Kiev" story and lied about Bucha. But, they'd never, ever fudge the number of tanks they have destroyed.
You are an idiot.
People who have collected images of destroyed Russian tanks. You can read the list here. If you think they have made an error please submit your correction.
The list is not maintained by the Ukrainian government, and about the only thing they had to do with it is destroy, damage or capture the tanks shown. While you are at it you can look at the hundreds of destroyed Russian trucks, armored personnel carries, infantry fighting vehicles, and aircraft.
