>Why would you do this over using explosives or even a gun like the Ukrainians have?
It's cheap and if you're intercepting drones over your territory, there's even a chance you could recover the drone.
It "probably" only needs new props and possibly struts, most of the frame, the camera and comms boads and especially the FC stack are probably intact.

>Could this be used also against infantry?
Possibly, vidrel, a Russian FPV bonks a Ukie on the head and fails to detonate.
I think the OP trident is relatively unlikely to penetrate a ballistic helmet or plates which means it takes more precision than is possible with drones v people and even if you avoided the plates or went for the legs, there's no guarantee of it being lethal.
I wouldn't want to be stabbed by a 3kg blade travelling 150kmh but the chances of survival are decent if it doesn't hit you between the top of your vest and the bottom of your helmet which is mostly the only lethal target area for it.

Mostly, explosives are just going to be better against infantry.
However...
