Ukraine’s Ministry of Defense has called on all citizens of Kyiv who own hobby drones to bring them in and help monitor the city as Russia invades. according to a new Facebook post by the military. Even if people don’t know how to fly their own drones very well, they’re still being encouraged to bring them in so that experienced drone pilots can put them to good use during this critical time. “Do you own a drone? Give it to experienced pilots to use!” the Facebook post says according to an English language translation.
