Build up a decent army and rebel.
Oh and stick with one unit chassis, vehicles/cavalry always work good for me because they can take out the best chassis (heavy, tanks) with ease and you need a lot of infantry to beat them.
The ratio I use for vehicles is 5/5/5, the ratio for infantry I use is 10/10/10, and the ratio for tanks I use is 3/3/4.
Btw, by like 5/5/5 I mean 5 armor, 5 damage and 5 range in each squad.
Oh ya. Don't forget to vote every day at this link for blue tokens http://www.battledawn.com/?p=vote
And consider becoming a supporter and buying reds. Reds are fairly cheap and help out a lot, they also offer advantages that non boosting players don't get. Remember, boost workers before anything else because they give you power and score, and increased resource production.
Conserve resources and make wise choices. And finally, be active!
