Let's see here.
I need to create a army of combine soldiers.
Next I have to create Dropships to put the Combine Soldiers in.
Okay.
I spawned 300 Combine Soldiers and enough Dropships to carry the Combine Soldiers.
I spawn 50 Gunships to escort them.
I create the portal to send them to Earth.
I send them through the portal to enter Earth.
I have them strike Military Bases.
The Military fights against us.
( This is the first time they have been attacked by a force from an unknown planet )
I send a Dropship that is carrying a strider.
7 Hours Later
My civilians. As the president of you all. I have sworn that we will never fall. We will never surrender.
We will never give up. But, I'm declaring, we will surrender, to the Combine.
