Not really, at least not with the present anti tank weapon systems.
Anti tank weapons get better, then the tanks get better protection.
Try to perforate the armor of a T-90, even when a T-90 shoots at point blank against another T-90, it can't penetrate the armor, so how are you going to defeat that tank? Not easy, air launched weapons probably or lucky shots.
How about when a tank uses active defense, how do you hit that tank?
The latest Merkava has active defense and in the last Gaza war, 1 tank defeated 7 antitank missiles, so how do you destroy tanks like that?
Active defense keeps getting better by the way.
The reality is that the tank continues to be the king of the battlefield, but that only applies to modern MBTs.
Did any country ditched its tanks? NO, that tell you something.
What
@Viet said before about tanks used as infantry support being outdated is correct but only applies to modern MBTs. For older tanks such as T-54 / 55, the correct role is as infantry support (like an IFV), so what the Vietnamese army is doing with them is correct and makes sense to upgrade them (cheap local upgrade).
You tell me in detail how you can easily take out a modern tank like T-90 (not even talk about Armata) that has active defense.
Those IFV vehicles that you like such as like B1 Centauro , BMP-3 , M1128 are actually the ones that are very easy to take out (unless they have active protection as the US is starting to do with the striker).
For an IFV you do need to be light (and vulnerable), that's just part of the job, but if you want the heavy firepower on the move and difficult to defeat, only a modern MBT can give you that.
