Using F-15s/A-10s to hunt for Shaheed launchers is inherently susceptible to ambush. They are doctrinally driven to attack the launch teams because of their theory of victory, when intercepting vehicles in flight is much safer.

If the USAF had combat capable drones, for ISR, ground strike and intercept, that wouldn't be such an issue. But their ISR drones are too slow and expensive, same with Reaper.
