You need to elaborate the math :)
The Ukrainian drone at $1.2K is reusable with a shotgun. So your ROI is much, much higher than if the Ukrainian FPV drone was a kamikaze drone.
Brilliant!
More like $5 vs. $10K - the cost of the shotgun shell. Of course, you have to amortize the cost of the hunter drone over the number of kills. If it kills 10 targets, that's ~$125 per kill. Now that math works.
More like $2 for the buckshot and a bit of fuel or electricity for the drone.
Less than $10 and the Ukrainian drone can be reloaded and recharged/refilled
