TvT: 1-1-1 3reaper 1hellion Cloak Banshee

Although it has been around for a while, it was when I saw  oGs_Supernova do it at the IEM Season VI World Championship at Hannover when I really got interested enough to try it. This is still a relatively new build that I've been doing, but I have been having great success with it, especially against fast expand builds. It is insanely aggressive and very micro-intensive, you have to be so careful to continue macroing properly while executing this build.

10 supply
11 gas

13 rax

16 tech lab
16 OC
16 Reaper
17 fac
18 gas (2nd)
20 Reaper
22 supply
22 Hellion
24 port
+ swap port with rax ASAP and begin Banshee/Cloak

Immediately at the end of this build order you will have around 400 minerals and no gas (this may vary a bit), I usually drop the Command Center at this time, however there is always the option to go ahead and one-base all-in or build a bunker and some Marines to be safe and get a later Command Center.

EXECUTION: This is a very very micro-intensive build that is optimal on Reaper-friendly maps such as Tal'Darim or Shattered Temple and can not be afforded sloppy control. The are many ways to execute your attacks from this build, I like to pop up with with first Reaper to scout, see what I can do, then get it out alive. Once your Hellion pops you can opt to attack, even up the ramp if they don't have a bunker or simply use the Hellion on lower ground to cover Reapers up on higher ground - you can be really creative with this, the idea is do kill as many Marines as possible for the Cloak Banshee follow-up that can do massive economic damage. IMPORTANT: Killing an SCV building something is great because it slows down the other Terran's tech/production.

IN GENERAL: This build can transition into anything: bio, mech, sky Terran, as it ends with the infrastructure for any; however, you are very light on units early on since you tech up so quickly and go gas first. This shouldn't be too much of a problem since your Reapers/Hellion should control the map early on and your Cloak Banshees that follow (build at least 2). Although this is a very aggressive build that usually causes a player to be overly passive, you should always play a reactionary game and be mindful of counter attacks. Also, a well-executed proxy 2rax can outright kill any gas first opening, especially this one since you skip the first marine for the faster tech lab.

TvT: 1-1-1 Banshee Expand

Let's face it, 1-1-1 is a very common build, especially in TvT. This is a variant I use every Terran from SlayerS_Ryung to ZeNEX_Byun (see what I did there?). With good reason, it's a solid build that has few holes in it with a lot of advantages. On bigger maps I'd argue the gas first build is better, so knowing that version is also great if you play T. However, you don't get out the tech too much faster so, meh; it feels much safer having more Marines in the beginning.

10 supply

12 rax

13 gas

15 Marine (constant)

16 OC

16 supply

18/19 fac

21 gas

+ 1x Helion, port (when fac is done)
+ supply

+ tech lab (on fac once the Helion finishes)

+ switch port onto tech lab

+ 1x Banshee
+ CC

+ = get/do it ASAP

EXECUTION: This is a standard opener and you'll do all the normal things you'd do. You have to bungle it up pretty bad to auto-die in the early-mid game. Your first 4/5 Marines should be making their way towards the enemy base, clearing any watchtowers along the way, once your first Helion starts making. The idea here is to scout the front and possibly kill some marines. If they have a bunker, just back off (duh). Best case scenario, they were a bit too greedy and you end up killing a lot of marines. Either way, you're just thinning the marine numbers. If they went Marauders, run back to your base and build a bunker, then proceed to win or get way ahead with the incoming Banshee. Just make sure you watch and micro your Banshee(s). They not only serve to harass, but scout as well. If you suicide your Banshee into marines, you will hence be known as TheBestfOu.

IN GENERAL: Your first Banshee will scout and pressure your opponent while you expand and macro up back home. Unless the enemy got a really fast Viking or Stim, your Banshee will do damage. Depending on the situation, you may want to get another Banshee. For example if you spot an FE, with two Banshees you can harass BOTH of the other T's bases. If you spot he's going Banshees, get a Viking or a Raven! I don't usually opt to get cloak, it's a big investment and the Tanks Siege Mode comes out so much later that if he holds well and counter-attacks you might die.
