Ukraine has been using cheap interceptor drones (models Sting/Bagnet/etc) combined with sensor networks to intercept slower prop driven Geran-2. Then Russia upgraded to jet engine on Geran-3, with higher speeds that are more difficult for prop interceptors to catch. Ukraine switched back to using machine gunners from aircraft to help take those out until they develop faster intercept drones.
