In the snowy streets of the north Ukrainian town of Trostyanets, the Russian missile system fires rockets every second . Tanks and military vehicles are parked on either side of the blasting artillery system, positioned among houses and near the town’s railway system. The weapon is not working alone, though. Hovering tens of meters above it and recording the assault is a Ukrainian drone. The drone isn’t a sophisticated military system, but a small, commercial machine that anyone can buy.

Since Vladimir Putin invaded Ukraine at the end of February, drones of all shapes and sizes have been used by both sides in the conflict. At one end of the scale are large military drones that can be used for aerial surveillance and to attack targets on the ground. In contrast, small commercial drones can be flown by people without any specific training and carried around in a suitcase-sized box. While both types of drones have been used in previous conflicts, the current scale of small, commercial drone use in Ukraine is unprecedented.

Drone videos shared and posted to social media depict the brutality of the war and reveal what has happened during battles. Drones have captured fighting in the destroyed Ukrainian city of Bucha , with lines of tanks moving around streets and troops moving alongside them. Commercial drones have helped journalists document the sheer scale of destruction in Kyiv and Mariupol , flying over burnt-out buildings that have been reduced to rubble.
