It will be the final form of all emulation I do from now on.
Currently syncthing to a server manages sharing my states and saves between steamdeck, bazzite home rolled steam machine and Desktop. This would be the dream for portability, and user sharing!

Honestly, what can you do? Most of these guys barely have time to pull the trigger without aiming before the drone is in death range. A bunch of the clips had a second drone watching from a distance, probably ready with a second charge. Maybe you get lucky once, I doubt you get lucky twice.
You could imagine solutions to an explosive fpv drone in a test range scenario. Maybe flechette/buckshot from a 40mm grenade system. A net thrown like pocket sand.
I don't see how any of these are practical in the open field, or with <5s reaction time.
EMP is basically useless here, what you could make with what you could scrounge in the field would only be useful in death range of the explosive.
Assuming you could juryrig a signal scanner and reliably figure out what they were operating the drone on, maybe you could turn a field radio in to a jammer, if you're lucky. But now you're a walking black spot, that's broadcasting its location constantly. They still only need to lose one drone to signal interference to know somewhere near there's an artillery target - and even civvy radio operators are really good at finding illegal signals by triangulation.
Eventually something will be thought of to provide some sort of counter, but I don't see how that's going to happen without extensive testing and time. Military equipment and manufacturing does not change overnight. War doctrine takes even longer to change.
