If you want to Warthog rush, go Anders and when the match starts bulid a supply pad, then a recator, then just more supply pads.

Go and collect supply crates and buy, then upgrade your supply pads. Just save up, then buy at least 5 warthogs, then you upgrade to machine gunners and destroy a few bases.

Keep building supply pads and 1 recator, then upgrade them and when you have 10 warthogs upgrade to grenades. When to guass cannons.

What I do is get about 15 and attack their base, and while they keep them busy build Hawks.
