As a Terran you will probably be in the position to react to your enemy rather than pressure them into something (Unless you went reaper rush to make them get roaches (or mutas)).
Wall off, spend your minerals constantly. If you ever get over 800 slap down turrets / expo / barracks and keep it down. Reactor rax is fantastic to making that delicious DPS meat ball known as marines.
Tiny unit size + great DPS + range + Mineral only = Best damn unit in the game (Before they fix tanks more).
Is it just Terran, or just not doing so well at SC II?
Well I'm only using them for now, then learn the others later. Only ever played the others in SC1.
I will try your tips!
