- Hit early with Marines / Hellions, don't forget to bring along some SCV's for possible bunker placement as well as Hellion repair
- Start building your Starport just before you hit, this will allow you to imeditaly follow up on your first push with some Banshees
- If they do get a ton of Banshee defense ( Queens / Spore Crawlers ) then push out again with Marines / Hellions, don't forget to expand so as not to fall too far behind
NOTE: Build orders should never stay static and are subject to change based on what your opponent is doing! Remember this is an RTS: use your brain, be adaptable, profit.
