hahah,yeah but its hard to use gun only if you are against 4 or more guys,Gun kills are my fav though.
Fun fact for dealing with EJ: If he's running ECM, SAAM his ass. If not, get an S/MTD out. He never was able to fly that plane properly, as proved when I wiped his ass out when we were both in one :'D good times. And for those times you're outta missiles, just hit Start -> Respawn for a reload.
As for tactics, yeah, campaign pretty much teaches you how to die rather than survive. Gun the engines and weave about like a mofo. 4AAMs/QAAMs are your friend.
