One One One Barrack Factory Starport Build Order

The one one one strategy is a Terran strategy in StarCraft 2 where you build one Barracks, one Factory and one Starport. From there you get a healthy mix of Tanks, Marines and air units to push into your opponents base with. This is a strong mid-game strategy and allows for easily transitioning into alternative builds or units.

[Terran Build Order]

10 Supply Depot
12 Barracks
13 Refinery - send 3 SCVs when it finishes
15 Orbital Command
16 Supply Depot
When you acquire 100 gas, Build Factory and tech lab when it finishes
Build Starport when the Factory finishes.

Scouting Needs:

Optimal Map Conditions:

Scout your enemy base to see if they are cheez rushing or going for an early rush (4 gate, M&M push, Roach/Hydra, etc.).

Medium to Large sized Maps work best for this.


Vs Terran:	Vs Protoss:	Vs Zerg:
Scout the Terran carefully for proxy reapers. If he acquires an early refinery, it could be a warning for early cheese. Build a few more marines is a good measure to stop this. Early marine marauders can put a lot of pressure on this build. You need to establish bunkers at a choke.	Scout the Protoss Player and see what he is going for, If he gets two gateways before gas, he could be doing a zealot rush. Build a bunker with marine inside in almost all situations to stop stalker harassment. Marines gain an 1 range from 5 to 6 inside a bunker. This is important because stalkers can kite really well with its 6 range attack and fast movement speed.	If the Zerg player goes for two gas or not teching very fast. You can bet that the player is going for a fast baneling bust or roach build. Build bunkers and use your starport and factory to block the choke instead of supply depots. Starport, Factory and Barracks are more durable than supply depots.

What to Watch out For:

Scouting is the key with this build order. If the opponent is going for some kind of cheese build like fast void rays, mutalisks or dark templars, make sure you build the correct counter from each production building.

Tips for Pulling off the Attack:

After the completion of the barracks, you can either build a few marines or get tech lab for marauders for base defense. In addition, make you block you base off using your barracks and supply depot. This will ensure that you can tech safely.

Transitioning out of this Strategy:

This build order is very verstile since you have one of each building. If you want to commit a specific path, you can just construct more of that building. IE: Build extra barracks for Marine Marauder ball. With this strategy, you really want to win with a strong mid game push once you have a couple units of each.
