In the last two minutes of this video, you can see quite a few FPV of Saudi mercenaries being hunted down by Yemeni fighters. But to know how these small birds were hunted, you should pay attention to this picture. The Yemeni army recognized the field situation very well and put the appropriate weapons into its fighting organization and actually prepared skilled shooters armed with shotguns to hunt these small birds.
The fact is that currently the only solution for these FPVs is only those shotguns that can shoot down these UAVs with precision and a high probability of hitting.
