This attack profile with terminal dive and speed IMHO is almost unmistakably Spike.I don't think they're using Spikes either, which are a heavy ATGM with line of sight firing out to the km level.
FPVs would be far more effective with NLOS attack out to 10 km level.
All of their other purpose build drones are huge and very difficult to smuggle. FPVs make far more sense.
Lancets etc imho slam slower and their motion feels different.
Copters fly fly different altogether.
But find some spike or almas footage - almost exact match. Plus shitty old cameras with digital IR feed. this is not our usual fpv mix.
