Drones can lay mines, deliver everything from ammunition to medication and even evacuate wounded or dead soldiers. Crucially, drones spot any movement along the front line and are dispatched to strike enemy troops and vehicles.

President Volodymyr Zelenskiy said that Russia launched 597 drones and 26 missiles, killing two people, wounding 20, and damaging civilian infrastructure from Kharkiv and Sumy in the northeast to Lviv, Lutsk, and Chernivtsi in the west.
