This is a Starcraft 2 strategy for a game of Terran vs Terran.
It's an early game strategy and the goal is to create a Banshee as fast as you can and have it attack the opponent.
If done right, this should give a great amount of pressure and damage to your enemy's army.
When you have gathered enough minerals, build a Refinery.
Do this before building Barracks in order to have 100 gas in stock by the time the Barracks are done.
After that, you can build a Factory.
Having a couple of Marines and Hellions will make the Banshee rush more effective.
When you have enough resources, start building the Starport.
While the Starport is being built, add a Tech Lab to the Barracks.
When the Tech Lab is done, lift the Barracks off so that you can train more Marines.
When the Starport is finished being built, lift it onto the Tech Lab and start creating a Banshee right away.
When your Banshee is ready to go, make the rush against your opponent.
Take your Marines and Hellions.
You can also take SCV's with you to take on some of the damage.
This attack should destroy most of the enemy's army.
The attack can be useful for establishing your expansion.
You can prepare for the expansion by creating a second Command Center before the Banshee attack or even while you make the attack.
In order to make this happen, you must make sure to have enough resources before making the attack.
This is an early game strategy, so you have a lot of options after the Banshee assault.
You can expand your army by building a third base and build up an army of Tanks and Vikings.
