ISF

The ISF (Inter Stellar Fleet) is an organization made up of the Earth's combined governments. It is a human faction.

They protect the Sol system and Earth at all costs. Their technology is much more advanced, because they have to compete with higher powers like the Shade. They also have technology stolen from the Shade and other alien races. Some technology is given to them, too.

They use more powerful variants of the fighters from days past, with Crystals incorporated into their power sources to increase their capabilities. Their naval ships are massive and just as deadly. Their spaceships are fast and deadly. Their land forces always have a surprise for the enemy, such as giant railguns or deadly experimental explosives.
