At this point you're just thinking of a crappier, more expensive, electric MANPAD. It would not be trivial to make one of these that can climb to 1km and acquire a target 2-3km away at over 200km/h.

You'd be better off with a solid propellant, saclos guidance, and a fragmentation warhead.

Wouldn't even need propellant for these, Rheinmetall has some ammo they program as it's leaving the barrel to fragment just a couple metres before the target

Yes, the issue is guidance though, bullets that can maneuver are extremely expensive also.

After viewing the Optical Remote Control video (the last on the page), I wonder if they only use artificial turds for training purposes, but drop live turds on actual Russian jammers?
