The basic working principal of a cm is it just like a jet powered drone which follows predefined waypoints and in terminal it may or may not have man in loop like control where remotely guide the cm to target but in new gen cm it removed and added image based or corodrinate based target attack ( man in loop system vulnerable to ew and control system failures),and more over effectiveness of cm dependent on three factors size , speed, fly path, for example a subsonic cm with terrain hugging config with small size very difficult to intercept which make it most favorite weapons for long range standoff attack like Strom shadow and Turkish and Korean counterpart's, now consider air launched bhramos which is supersonic in nature and have completely dynamic fly path or operational path which make even difficult to intercept becoz both intercepter missiles and targeting supersonic cm in mach 2.2 above régime so control laws and predefined point to intercept have to change very nano second also even u do the successful interception chance is less than 30% ,also only few Sam system have this ability and they are western origin, so I hope I answered all your doubt's and my view on new Pakistani toy
