No, sorry, I couldn't find any info neither for tyrrs nor for tanks; i just don't remember, it was either some video or internet article, and i didn't bother to have any "prooflinks".
If you know korean/russian, and you found wrong/conflicting info, you may elaborate/add/comment on anything, since , who knows, some of the news were translated from one language to another 5 times, and, lost their accuracy/meaning, or i was "hearing things".
