The air-to-air radar modes require quite a bit of explanation.
If you grew up with air combat simulations in the Eighties and Nineties radar was a very simple concept to understand. You largely had a 360 degree view of the world around you. But that isn't the case with modern air combat simulations.
And neither are radar guided missiles simple "fire and forget" instruments. You have to understand their limitations as well as their strengths when utilising them in order to maximise their chances of taking down their designated targets.
This video tutorial introduces the Fire Control Radar and its Range While Search mode, and combines these concepts with the AIM-120 AMRAAM radar guided missile.
