I know there's been a bit of a discussion about the feasibility of various factions salvaging whatever armor they might try to beg/borrow/steal etc. museums, private collectors, etc. Well, here's an interesting tidbit where it seems, indeed, the Ukrainian rebels broke into a museum to do just that:

I wouldn't go so far to say the T-54 tank is strictly a museum piece, though. Sure, it's old enough to be my grandfather if I had one, but there's still quite a few of them around the world still chugging along in use, that and the T-55. I don't remember the exact numbers, but it seems the T-54/55 were the armor equivalent of the AK-47, as in they've been sold by the trainloads all over the planet. I'd be amused to see a T-34 show up at some point though, and I've heard rumors of those still operating in spots here and there...
