I really don't think that's a good comparison, cavalry didn't just fall from grace because they became easily slaughtered by infantry, they stopped being used because their role became irrelevant and were replaced. The role tanks play has not become irrelevant and while they aren't as survivable as they used to be they aren't nearly as vulnerable as clips from UA seem to imply.

I'd recommend this video by a former Abrams commander and tank historian who presents this argument far better than I can. https://www.youtube.com/watch?v=lI7T650RTT8
