Cruise missiles use terrain following radar and GPS and Digital Scene Matching Area Correlation (DSMAC) II navigation system, allowing three kinds of navigation: GPS-only, which allow for rapid mission planning, with some reduced accuracy, DSMAC-only, which take longer to plan but terminal accuracy is somewhat better; and GPS-aided missions that combine DSMAC II and GPS navigation for greatest accuracy.and fed the right target info you can pick the door or window you want to hit.
Antitank missile probably wouldn't have sufficient warhead power to do the damage that was done.
