Meet Yevhen Pronin, acting president of the Ukraine track and field federation. A few days ago, he was at the world track and field championships in Eugene, Oregon. Now he’s back at war, using armed drones to blow up Russian tanks.

Because his mobile drone operating group is so very good at what they do, the Russians have put a bounty on their heads.

In one intercepted phone call, he said, the Russians talked about a specific amount — rumor has it, maybe, $10,000. In another, it was said that there would be a reward, without details.
