This is a very strange war. The Ukrainian soldiers in the field all have cell phones and they're taking pictures of destroyed, abandoned or captured Russian vehicles and they're being posted to this website:

When you open up the website, scroll down to where they list the various types of vehicles and the number that have been destroyed, abandoned or captured, and if you click on these entries, it will show you pictures taken by the Ukrainian troops. The pictures are timestamped. Note that this website is being continuously updated since when I first found this site, it listed that 54 tanks had been destroyed, abandoned or captured, but just now it's showing that the number is up to 60. But if you got through the entire list, you get the impression that the Ukrainians are capturing almost as much equipment as they're destroying, and having been part of what once was the Warsaw Pact, they're familiar with these types of vehicles and should be able to put them to good use quickly.
