At this point, what difference does it matter?
As the first Challenger (they have been in hiding) lost it’s first challenge, destroyed, it highlights the western wonder weapons are just like any other piece of hardware, very expensive losses, Bradleys, Strykers, M113, MRAPS ….in huge numbers.
The world is watching, hopefully those countries shopping around for equipment opt against high priced western arms thus slowing down our defense industries profits.
That said, the Brits “ undefeated” Challenger II has now been defeated- by Russians. The world is watching.
