Lots of experience and skill points
When you first take control of the robot guy in miltia (i forget his name) you have got to go meet your friends.
Go find them and then you get a couple of cutscenes where you get chased by e.s. Robots. Anyway carry on with your mission until you get to a cutscene where you see a helicopter that drops 4 p.s.s. Soldiers.
Defeat these guys and just keep waiting for the beam fence so you can get yet another battle. Keep doing this over and over until your on at least level 20 because you have a really tough boss battle to do later.
