I don't see the issue with taking out armour as a jet, it's literally ez mode and I'm no way an amazing pilot. Just fly round all happy spamming Q spotting everything. See armour on minimap, bank out to the edge of the map, swing back in, fire all rocket pods, if most were on target it should be disabled (you don't even need to touch anything apart from fire once you're lined up - easy) then just switch to guns for vehicle destroy + kill.
Also, air radar is an awesome upgrade.
Air radar, flares, rocket pods is my current load out.
No one decent in jets uses heatseakers so no need for stealth, which everyone seems to love. If you get locked on by AA, stinger or heli just fly away from it with afterburners, you'll be out of lock soon.
As for the AA, even if they get a lock you only need one flare then you're free with your rockets. If they try their cannons, as has been said, just approach from further away. Honestly, the rocket pods should be more than enough to kill anything on the ground. (Apart from infantry, which are pretty much invincible to like 10 rockets and 100000 cannon rounds).
