Kills... Get kills. Oh and have a fast tank in your load out to get the first base caps of the game for early points. Like the BT-5, M2 2ND Locust, or the Sd.Kfz. 234 (Better known as the Puma). Don't go off alone and try to stay more in the back. Don't go Urban or Close quarters fighting unless you're very good at it.
