Ukraine's army issued an instruction video on Monday with a step-by-step guide for Russian soldiers on how to surrender to one of its drones.The footage suggests that the role of unmanned aerial vehicles (UAVs), commonly known as drones, on the Ukrainian battlefield is rapidly expanding, even to the sensitive area of surrender.In an earlier interview with the Kyiv Post, the project's spokesperson, Vitaliy Matvienko, explained that Russians can even contact the hotline pre-emptively, to register an intention to surrender ahead of being physically sent to Ukraine.In late November, Ukraine's Ministry of Defence shared drone footage showing a man in a Russian soldier's uniform walking with arms raised — an example, it said, of a drone mediating a surrender.In November, Russia's Ministry of Defense said that it had also used drones to transmit text messages enticing Ukrainians to surrender, state news agency TASS reported, though it is unclear how successful the initiative has been."
