AI's missiles do not obey same rules as players, keep that in mind, I experimented A LOT with it. My Russian missiles are not dead weight, vanilla R-27 is about as good as 7F while later versions(mainly 27ER) I've set up on par with 7M as they really were upgraded a lot.
Also no Russian Alamo was ever fired in anger IIRC, downgraded export versions were so comments about that are dubious at best same as about the planes as that is the Russian export policy.
However all that is futile anyway when AI can fly more or less strait poping decoys I call "Burning B-52's Mk1" and easily fool the same missile I can't avoid doing 12-14G manouver trailing a wall of decoys.
All in all Blackbirds advice is the best and in my install valid for all planes, as soon as you get tracking sound from your RWR, dive to the deck wait for it, pop out, fire your stuff and run like there's no tommorow ;)
