I used to constantly run the jetpack with heavy armor and a laswr cannon.
I would jump in a base as my friends were circling a base, cut down the chaff around the entrance, switch to scorcher and take a priority target.
Worked really well but damn those rocket troops... They normally had the precision of a storm trooper, but they would curiously snipe me mid-flight with a missile to the chest and ragdoll me out of the base
