My tactics for taking a clever jet down.
Take out heat-seekers.
Lock on and shoot one
Enemy puts on flares
2 per load, reload really fast.
Shoot the 2 at the guy again.
Disabled
Blow up in mid-air with MG.
Also, I absolutely LOVE piloting in Nosahr Cbrown towns, I have Stealth, Heat-seekers, and flares, and it's awesome to watch the helos on the enemy team be taken out by my 2 heatseekers and MG in an instant, without knowing what hit them. Awesome.
