I am by no means an expert, but what I have gathered is that it, like almost everything in combat, is incredibly complex.
With the correct support and combined arms usage tanks are an absolute devastating force on the battlefield still. Used correctly they can completely change a battle.
But they aren’t war winners by themselves, and have never been. Unsupported a single tank is exactly a big expensive target, just like a modern fighter and or a single soldier.
The idea that tanks can be wonder weapons and that they alone can turn the tide of a war has existed since WW2, but they have always had weaknesses that need to be covered by supporting elements in order to be used effectively.
How the Abrams will do in Ukraine is anyone’s guess. The Abrams has never seen combat without the might of the US’s military logistics backing it up.
All that being said, if you are in a firefight, would you rather have a tank backing you up, or not? I’d take the tank support.
Not 40, but weather news hits different when the cold/humidity fucking hurts your bones.
