Can you provide any evidence that they actually went after Kharkiv in earnest other than blowing up some military targets? They'll probably eventually take that city as it is historically and majority Russian. As for the (retrofitted) T-62s, those are mostly given to the Donboss militias and a perfect tank to use in the already conquered rear. They are still armor and they still function. US also runs some old gear if you didn't know. As for the dud rates, I'd expect that for older missiles. Their new stuff (which is more advanced than anything the US has) is less than 10%. And it's clear they're not running out any time soon despite western media claims two months ago that their weapons stocks were days from depletion. On the other hand, the dud rate for western supplied Javalins and NLAWs is around 80% as reported by Ukrainian military personnel. And it's actually now illegal for Ukrainian troops to publicly criticize the effectiveness of western supplied weapons. Let's stop projecting and be honest about what's actually going on.
