That was my takeaway from it.

We’ve rarely been involved in wars where a main battle tank would be key - probably the Gulf War but we hardly met any opposition there. They are designed for the kind of situations you encounter in world wars (a similarly equipped strong dug-in opponent) and the invasion of Ukraine is the first time they’ve been deployed on a, if you’ll excuse the pun, challenging battlefield.

I can see how they’d be useful in pushing through the layers of fortifications the Russians have thrown up in the south but they are also much more vulnerable. If a drone can call in a missile on your position then a main battle tank has to be carefully deployed with a lot of support and countermeasures or it’s a sitting duck. Just bunging the Ukrainians a few Challenger tanks might not be enough.
