- Enemies can steal tanks if you jump out, don't jump out.

- Do not attack enemies with the repair gun, it doesn't hurt them.

- Don't just go for the expensive guys, everybody has different uses.

- don't spam "I need repairs". Say it once and tell people where you are. If they're around, they'll help you out.

- Don't go pulling a Rambo on the enemy base, use teamwork, coordinate attacks and defences with teammates, talk to them, you'd be suprised at what outcome you get. Heck, I saw one, and only one, rambo movie. He's sitt'n there on this rock and the general wastes his Machine gun trying to kill him. He chucks that and shoots his pistol ammo at him. At 10 feet away he doesn't hit the dude once. Rambo is just standing there looking at him. I turned the TV off right there. That doesn't work in real life.

- You can hit "J" and see what everybody is and if they have a vehicle, try to be something different. You need everybody to win. An army of just one type of guy will die.

That's all i can think of right now.
