Nice, but...
I'd contest that this war is demonstrating that armoured vehicles don't have a strong place on the battlefield.
I know Russia is showing us exactly how not to do it, but I can't help feel they must have had some basic idead about what they're doing, but the landscape and situation has really ballsed it up for them (thankfully).
Consideration...
Russia has (some) air superiority still, and probably could get it's shit together with some decent targets
All the issues of logisitcs would apply to UK sourced vehicles and parts - and remember no NATO staff to maintain them, some MBTs are high maintenance.
Looking at the shots we do see of Ukraine, I wonder if the flat/muddy landscape is torture for vehicles at risk of light missile fire.
To be clear, awesome, and I am 100% emotionally engaged in Ukraine hurting Russia just as much as it can. But looking for reasonable discussion!
