Not entirely unrelated, but FPV drones are now the main weapon of the Ukraine war. They started using them against tanks, then groups of soldiers, but have now found that they are cost effective enough to go against individual soldiers.<p>The drone soldiers operate in small teams from underground bunkers close to the front from which they launch hundreds of drones a day, with different types of drones for different targets. The limiting factor is the amount of drones, Ukraine plans to build one million of them this year domestically.<p>Apart from jamming, there's not much to defend yourself against drones except staying underground, or moving fast enough that there is no time for you to be spotted and tracked. But drones can see kms away and move at hundreds of kmph, then go after you personally, even inside buildings, and even at night with infrared vision.<p>In an interview they asked a drone-ace how many ennemies he killed, he said he couldn't remember; "Do you remember how many cups of coffee you drank last year?".<p>I am not sure what to think about all this, but it is certainly fascinating
