You can do any battle or any faction in Clone Wars or Galactic civil war.When you are going to battle press right on the control pad a different soldier on your side will follow you.This will give you some extra fire power,but if you are a beter pilot get in a 2 man vielcle then press left control pad he should get in but be the pilot if the man following you is not if a pilot is following you go ahead be the gunner.
