If I may put on the “credible hat” for a moment: it would make a hell of a lot of sense if Korea, Poland, and Ukraine worked out some sort of deal to do some “battlefield testing” of the K2 - particularly since Poland just bought like a thousand. And if they iterate on the design using the feedback from Ukranians tankers, it would be the quickest A2/Mk2/block 20 turnaround of any modern MBT, bar none.
