I read somewhere that if you had enough time, the best way to evade an enemy missile is to make 2 sharp turns (I forget if you had to turn in any specific direction)
Probably not too often would you have enough time I guess.
I did see an interesting review of the (much talked about) US/India exercise done some years ago. While most people were yapping about the SU-30MKI (the Indians touting how it 'defeated' the American F-15s, and the Americans touting how they could easily time the Flanker's end-of-thrust vectoring envelop to come in for a gunkill based on experience practicing against the F-22's TVC), the real but ignored story from that was the use of jammers to squeeze the engagement envelope of radar-based AAMs to the point where both planes were withing visual/IIR-missile range. Not just jamming the plane radars, but the missiles as well. Now, I know there are missile homing modes that simply shift to home-on-jam, but it was very interesting to see how Indian MiG-21s fitted with Israeli-jammers managed to get within WVR of the F-15s, and that it was those Israeli-specced-jammer nigh-obsolete Fishbeds that gave the Eagle pilots that toughest time ...not the Flankers.
Which is one of three reasons I have as to why the thought that air-war against a near-peer adversary will consist of long-distance BVR shots is very wrong.
