No wonder you consider M1A1 to be a Leopard 2A7V counter… if you don’t take into consideration one of the main parameters that define a tank’s capabilities.
A tank’s capabilities are defined by three main factors:
-Mobility
-Firepower
-Survivability
If you suddenly come in and say that survivability is irrelevant because “you just don’t get hit lol”, it’s no wonder you consider M1A1 to be a Leopard 2A7V counterpart- hell, going by that logic, even ARIETE should be a 1:1 counterpart to the Strv 122s as well (who cares about armor, just don’t get hit, right?).
Maybe you are an ultra-professional player who is virtually an invisible ghost to the enemy, like the Youtuber you reference; but not everyone is or plays like that; and when that’s the case, protection and survivability are what makes the diference between two tanks that are similar in every other way.
