These are the best-ever combat flight sim strat guides.
MiGMan thanks Chinofor this overview.
Falcon 3 Official guide was from 1994 (revised).
Art of the Kill was 1993 - it isn't really a strat guide, more an Air Combat Manoeuvering and Basic Combat Manoeuvering guide.
The graphic and caption below is from the F3 official guide -- I just liked the description of the SA-6 as a "delightful" missile.
Looking at these now, I see I have learned a lot in 5+ years, but there are things in the F3 complete guide especially that I can still learn from -- good explanations and diagrams, but I wasn't able to absorb it all back in my Falcon 3 days!
