Defense needs them everywhere, offense needs one gap in the defense.

I think Ukraine is already using mothership & hunter drones to target slow-flying drones (Shaheds and similar).

Very soon the most challenging part of anti-drone defence is going to be detection since fiber-guided drones can already fly tens of kilometers at low altitudes where they’ll be virtually undetectable with radar. You can literally fly them just above ground if necessary.

Ukraine is already using interceptor drones, Perun did a patron special episode discussing the development of these.
