What is obsolete is the doctrine of “armored warfare”, the idea that armor is the primary weapon on the battlefield that allows you to break through enemy defenses. In the days of trench warfare, tanks were a “disruptive technology” - an almost invulnerable mobile fortress that allowed armies to completely change the script on the battlefield by blitzing up the middle and breaking stalemates. Now that ATGMs are everywhere, armor is no longer invulnerable enough for this to be the main strategy - you need “combined arms operations” - infantry and air support to protect the armor. The Russians are not acting like this is the case, which is why their tanks are getting destroyed left and right. Armored vehicles will never be obsolete - if you’re sending in infantry or artillery or whatever, it’s still better to have armor for eg. small arms fire and shrapnel - you just can’t rely on its strength as the core of your strategy.
