Putin’s invading forces seem to be falling victim to Ukrainian attacks in the night. Several instances of Aerorozvidka, a tactical drone unit in Ukraine’s army, striking Russian units in the darkness have been reported. Ukraine’s small drones equipped with thermal imagers are able to locate Russian vehicles using heat signals of their engines. The Ukrainian drone units then bomb the invaders with Soviet-era anti-tank grenades. What’s making Putin’s forces easy prey for Kyiv in the dark?
