Top tip from me! Did this last night on a 1500 ticket conquest on Kharg Island.

If your playing solo on a big air map, start out as support.
Find somewhere out of the way with a bit of cover and drop an ammo pack. On Kharg Island I put mine in the rocks by the radio antenna. Then when you die (remembering to NOT drop another ammo pack in the meantime) respawn as Engineer.
Must have the Squad Explosive perk. The you start with 5 stingers/3 javelin.
Then hang around your ammo pack and shoot things in the sky to your hearts content, knowing you have a ready supply of more missiles/rockets.
And the beauty is, not matter how many times you die, the ammo pack will still be there.
