Funny I have been hitting those quite easily in the CA-Push campaign. I fly at him with my jammer on at around 8000', locked up in the TGP and Mav ready to fire, wait till he fires (usually around 6.9nm), fire my Mav and break and start kicking out a bit of chaff now and then. Also start jinking to make the missile lose energy. It gets close but not enough before it explodes and by then my Mav is nearly on top of him and he is still tracking me so he gets hit.
