THIS is the astonishing moment a Ukrainian armoured vehicle bravely takes on a vastly more powerful Russian tank in a ferocious firefight - and WINS. The astounding video filmed from a drone appears to show a Ukrainian BTR-4 raining hell on the invaders' tank in Donetsk, eastern Ukraine. And after pounding what is believed to be a Russian T-72 tank - a ferocious inferno engulfs and then obliterates it leaving the machine in tatters. First Rank Captain Anton Kuprin, 44, was killed after the ship was hammered by the missiles, according to Kyiv sources. While Mariupol is expected to fall within hours following weeks of courageous struggle which saw the port city relentlessly shelled by Russian forces.
