Ukraine's war against Russia is increasingly being fought by machines rather than soldiers on the battlefield. Far from the frontlines, commanders who once fought in some of the war's bloodiest battles now direct attacks through screens, livestreams and drones instead of leading troops into combat. A single operation can involve several explosive-laden robots targeting Russian positions without a single Ukrainian soldier setting foot on the ground, according to a report by CNN. The attacks are monitored from reconnaissance drones overhead while operators guide the machines remotely from control centres.
