Thanks for your answers.
You see, I had a nagging thought and remembered something and looked it up:
https://en.wikipedia.org/wiki/AN/AWG-9
The AN/AWG-9 and AN/APG-71 radars are all-weather, multi-mode X band pulse-Doppler radar systems used in the F-14 Tomcat, and also tested on TA-3B.[1] It is a very long-range air-to-air system with the capability of guiding several AIM-54 Phoenix or AIM-120 AMRAAM missiles at the same time using its track while scan mode.
So, the AirForce can employ multiple missiles in the air at the same time, while ground forces cannot.
Ok, on the other hand, the Air Force has no trees, hills, etc in 5000 meter height. ;-)
