If your playing MP have someone fly one of the seahawks and at the first hint of incoming vampires have him start poping off chaff. Helo chaff is just as effective as FFG chaff in decoying missiles.
Also make sure your not firing your SAMs at vampires that have already been 'thrashed' (IE shot down). Your see missiles on your weapons control plot in groups off two (three if your reciving Link data from an off board sensor) since your Auto TMA has not had time to merge them in to a single track so keep that in mind.
You can also jump over to the 76mm gun control pannel if your STIR don't go in to CWI mode and "unlock" the CAS system for targeting two targets at once.
EDIT: Also don't bother with Flares if your not dealing with weapons with IR seekers. Currently I think only the Mav, N-2 and N-9 have IR seekers (along with a few other small missiles). But that will change soon...
