Once a cheap answer to Russia’s artillery dominance, Ukrainian small and inexpensive first-person view (FPV) drones are now a force in their own right. They are used on a huge scale, with Ukraine projected to produce 2m this year.

Ukraine's air force said it recorded 110 Russian attack drones launched into the country overnight into Monday morning. Massed Russian drone barrages have become a nightly occurrence in recent months as winter approaches and Moscow targets Ukraine's energy grid -- as it did in the two previous winters of its full-scale invasion of the country.
