Rocket Netting - When using rockets, a useful tactic can be to use their proximity detonation to your advantage. Netting involves shooting multiple rockets in SLIGHTLY different directions giving your target less escape routes. I emphasize slightly because if done with too much variation, not only will your rockets most likely miss, but you'll make a large target of yourself as well. As with all tactics, this one takes practice to become efficient.
There's plenty more out there, create your own! And always remember to be flexible. Adapt!
