One reason why that the Terrans tend to be thought to be the best commencing class is that often their general strategy is less difficult to apply than than the other classes. Below is a fast track Starcraft Two Terran Strategy and ways to get you winning a couple of early games. With the Terrans, you will find three main builds that can be done. Though naturally there isn't a 1 fantastic strategy that will work with every game, these simple moves will apply to many games.
The 3 commonest sorts of build for the Terrans tend to be Infantry, Air and Mech builds.
Infantry
You have to be knowledgeable about the 4 primary infantry builds. Frequent starting builds in a game usually are for mass marines, or mass marines along with marauders. Typically, I have found that a mixture of marines and marauders is easily the most successful early build order, but there are conditions to this tip.
If you spy on your opponent and you see that he is rushing through air (not common in a Terran v Terran battle but common enough in Terrans v Protoss or Zerg battles), then it is a very smart move to react by building 2 barracks together with 2 reactors connected to them, after which push a marine ball out. You can then send it into combat for an simple win.
On the other hand, if the adversary is building masses of roaches or stalkers, you possibly can react using a mass marauder order, because they are the perfect counter for this type of unit in early stages.
The most popular Terran strategy around will be the MMM. Composing of marines, marauders and medivacs, the MMM is very simple to accomplish, therefore it is very commonly noticed in Bronze and Silver leagues. You will notice that as you progress, it becomes less popular though; within the Gold and Platinum leagues it is extremely rare because there are effective methods for countering it.
Air Builds
Another typical Terran strategy is to get mostly air units. Having said that, the best gamers hardly ever try this so perhaps it's not the best Terran strategy. Rushing banshees is a successful strategy whenever fighting versus Protoss and Zerg players, whilst Vikings really are a superior choice when playing versus other Terrans.
Air strategies are at their most reliable whenever a 'switch' is performed. For example, say you are a Terran gamer fighting versus the Protoss, and you are starting your huge MMM build, it may be predicted that the Protoss gamer may respond through massing zealots, colossi along with sentries.
Now is the time to fool the opponent. As soon as his forces are accumulated, pull off a fast switch and create 5 or 6 banshees quickly, and then launch an instant attack against the opponent. Generally, if he has not built up any kind of air defenses yet, you will be able to inflict some significant damage on his brand-new units.
Mech Builds
Mech builds are yet another hugely common strategy for the Terrans, and they are quite effective too. Commonly, this strategy consists of producing many thors and siege tanks. The siege tanks are able to cause great destruction upon opposing ground units, while thors can handle hitting most air units, whilst they provide protection for your tanks too. After you have performed this, you can include some Vikings to your forces, as well as hellions, based on what your enemy has.
Last but not least, using a few ghost units is another common part of Terran tactics, as you can assist your own forces by taking out some of the greatest value enemy targets such as immortals or infestors.
