Ukraine is already giving them to Russia, though not in the way Putin appreciates:
You do know that the Russians and Ukranians actually have some of the same tanks and such, right? No proof that that is actually a Russian tank burning there - remember, propaganda gets used by both sides. Sure, it could be a burning Russian tank, but it could also be a burning Ukranian one - it’s not got the distinctive hull shape of the one tank type that Russia has that Ukraine doesn’t (the T-14 Armata), and there’s not enough left to tell which variant it is of the types they have in common.
