First-person view, or FPV drones, are the latest in battlefield technology. Cheap, easy to produce, and simple to operate, they provide their pilots with a drone's-eye-view of the battlefield by beaming a video signal back to a VR headset. This means the pilot can make very precise manoeuvres - strap an old-fashioned anti-tank shell to the bottom of the drone, and you now have a modern precision weapon that can blow up tanks worth millions for just a few hundred dollars. Some people think they're changing warfare forever, so we're going to analyse a piece of footage and speak to a man making the drones for the Ukrainian army to find out.
