Terran 1 Barracks - Factory Opener

Overview

This is a popular opener as it allows easy transition into mid-game Factory/Starport plays.

The objective of this opener is getting a fast factory without cutting back on economy and openening your tech tree faster for a heavy mech or air army.

Build Order

Place your first Supply Depot at 10 supply.
At 11 supply build your first Barracks
At 12 supply build your Refinerry.
Imediatelly after your Barracks is finished upgrade to Orbital Command
End the opener with a factory right after your Orbital is finished.

Notes

As with many terran openers a wall in is required.You can go for a standard wall of 1 barracks with supply depots,but if you are facing a Zerg oponent i suggest walling yourselff with the Barracks and Factory.Zerg players have the habbit of busting terran walls with banelings ,and standard depot-barracks wall won't hold.

If you are planing for a heavy gas transition,you can build your second Refinery while the Factory is under construction.
