Україна Ukraine

I don't really understand what it's intended to defeat, though. Like, it's not clear to me that this does work.

Humans are pretty easily picking out the fake ones, and that's with just relatively low-resolution commercial satellite footage and a single static image. So it's not likely going to help if humans pick the target.

There are missiles that can recognize a target -- a tactic for anti-ship missiles, where the target is moving, and you just put a missile in the general vicinity and have it home in on the right thing. Those might use optical inputs as one input, though I don't know if something like this would fool them. But I doubt that something like that exists for specific aircraft on the ground or that that's what Ukraine is using. At least one airfield strike was conducted using those Australian cardboard drones, which are about as simple as a drone can get. They aren't going to be homing in visually themselves.
