Remember that state of the art Russian drone the Ukrainians captured that had a fucking Cannon DSLR camera in it? Yeah. They don't have "world beating" anything. It was smart for NATO to take them seriously right up until we had proof that they're full of shit. But now we have literally tonnes of proof, and it's all being dismantled and studied. Whatever surprises the Russians may have had for NATO aren't really surprises anymore.

Britain already sent some Challenger 2s. Before the Germans agreed to send Leopards or Americas to send the Abrams, incidentally. So it would be 4 types.
