The one in the foreground is a late model BTR possibly a BTR-70. The burning vehicle is a BMP infantry fighting vehicle. I suspect most of the so-called “light tanks” noted by ill informed journalists are BMPs. A vehicle with tracks and a turret is not always a tank. Even my frau knows that but she is not a journalist.
There don’t seem to be any obvious visible distinguishing markings and both sides still have these exact types in service to this day. Without markings or enough surviving visible equipment on the outside to tell variations apart, there’s no way to tell whose they are. There’s nothing obviously “Russian only, not Ukranian” in terms of the hull shapes. It could literally be either sides’ vehicles.
