Thanks FallenPhoenix, very helpful.
Yes, Fubar, I can see that you've moved the thread, and I'm okay with that. Furthermore, I can generally be counted as one that prefers more realism, than less.
Although, at the time I posted the question, I had no idea that either the AIM-9D was a Navy Only Missile nor that the F-4C was an Airfarce only bird.
Since I'm flying it in a Fictional Mercenary Squadron, involved in a non-historic campaign presented directly from the vendor, I'm not sure that I should have realized that all my B's were gone while there's a STACK of D's over in the supply window due to the previously stated historical facts.
Thank you & FallenPhoenix, again, for the clarification.
