Oh wow... Forgot about rush...
Pretty much the same concept as the longer version except, obviously, don't build defense. And instead of starports, build barracks and marines. The flamethrower guys (I forget the name, again its been a really long time) are good in close quarter combat. I found that medics are a waste of time when rushing because you can create more guys faster than the medics can save them. That's just my opinion.
