 Russian soldier makes unsuccessful attempt to throw out grenade dropped from Ukrainian drone. Russian soldiers tried in vain to throw out a grenade from the dugout which was dropped by a Ukrainian drone operator. A recording posted on social media shows that the grenade hit the edge of the enemy's entrance and fell back into the dugout. The unmanned devices have become a crucial piece of military tech for both Kiev and Moscow in the war, used extensively to scope out enemy positions, drop explosives and crash into targets. Drones are also used extensively for reconnaissance to spot enemy movements or positions. Another drone can be sent to attack the target or the intelligence can be used for artillery and tank fire or advances by infantry unit. Troops on the frontline have become increasingly dependent on and fearful of their potential. Drones are the eyes of our troops. The prevalence of drone warfare has triggered an arms race between Moscow and Kiev. Ukrainian officials say they need between 100,000 and 120,000 drones a month.
