hiting non-goal targets...

Hi!
When I do fighter sweeps I usually carry (2) 1000lbs or rockets to hit ground targets, besides my goal targets.
I also order my wingmates to hit ground targets after we eliminate the goal targets.
My question is: Does hiting non-goal targets afect the overall campaign, or is it just for gaigning prestige and kills?
