The most important thing to remember about Terran build order is that its economy is more complicated than other races. You will suffer a drop in the collection of minerals when you divert SCV is the collection of minerals to mine gas and construction of buildings. To balance this disadvantage Starcraft 2 incorporates the Mule. The Mule plays an important role in the economy and Terran is useful to get one as soon as possible. This strategy guide Starcraft 2 will give you an idea about Terran build order, and how and when to start the Mule.
Starting the game with 9 SCV and when you reach 9 build its first supply source Depot. By the time the deposit is built, you will have its 11th SCV so you can start building another depot right away. Using the same SA, build a barracks and put it to their blocks of ramp. Ensure there is a CVS at work in your Command Center all the time. Once the barracks are ready, use the VCS to seal the ramp over the construction of a supply depot. Build a refinery, once you get your SA 14. Cease construction SCV is the supply of 14 so you have enough minerals to upgrade to Orbital Command is built when the village. This will allow you to purchase the Mule faster. With the refinery built, 2 SCV acquire more gas in mines. Some Marines train to defend against any Terran Reapers Zerglings or your opponent can send out. You can build another barracks at this stage, unless you choose to upgrade directly to Siege Tanks and Banshees. You must have at least 50 Vespene gas by this point so you can add a technology lab for its first quarter. Orbital done with the command, invoke the Mule and keep doing the SCV. This is a default setting Terran. When the Tech Lab is built to pump out Marines and Marauders. Add a fusion reactor for the second barracks so you can train two Marines at a time. Upgrade concussion shells and Stim Pack on technology lab as soon as you can get an advantage over his opponent. This basic configuration will allow you to either strike quickly or have the defensive capabilities you need while you upgrade to Siege Tanks and air units.
Despite all this said, you should remember one very important point. This Terran build order is quite a standard. During the battle, depending on what you earn valuable information that scouting should be the deciding factor for a good earthling alphabetical order.
If your focus is only on the Navy and Marauders in Starcraft 2 strategy, you do not need a second refinery. However, it is recommended that you build one if you can. Gas is precious in the game and the more you collect, the better.
Terrans are a very balanced race. They have a versatile cast of units and a good position early in the game. They can block the lane quickly and foil attempts of scouting opponents. At the same time, it is advisable to use moderation as Comsat Mula is much more important in the game. If you are against a Protoss player, you may want to consider Starcraft 2 strategy for measuring a Shrine of Darkness, so you can be ready for any Dark Templars he can send.
There are many more Terran build order strategy. Depending on how the enemy is expanding, you might want to change its construction orders.
