StarCraft Battle Spot
Tank Rush
Build SCV's until you have eight supply used, then make a supply depot and two more SCV's. When your SCV finishes building the supply depot, order it to build a barracks, then have it go scout out your opponent(s). Build two more SCV's and construct another barracks, another SCV, then a supply depot. When your second barracks finishes build a refinery and put four SCV's on gas. Constantly build SCV's and marines from your barracks as well as making sure you keep up with supply.
Build an engineering bay and then a factory as soon as you have the money. You should have about 8-10 marines by now and should be aware of what your opponent has and what they are doing. Send your marines along with two or three SCV's to the outside of their base and build a bunker or two and a turret if necessary. As soon as your factory finishes, put a machine shop on it and research siege mode for your tanks. If you can support two factories, then build one outside their base. Rally your tanks and marines to where you built your bunkers.
If you think that they are going to drop on you then build a bunker, turret, and leave a siege tank next to your command center. If you have the extra minerals, (you should) build an academy so you can a comsat. Also upgrade your marines attack and range if possible.
Slowly build bunkers forward and as your bunkers are built move your tanks forward with them always leaving one tank in siege mode. Towers as necessary and repair any damaged bunkers or tanks ASAP. Your tanks will bombard there base from behind your bunkers and you get the satisfaction of watching a nicely executed tank push.
