What is the name of Jim Raynor's rebel organization in StarCraft II?

Jim Raynor's rebel organization in StarCraft II is called Raynor's Raiders.

Raynor's Raiders are a Terran rebel group led by Jim Raynor. They oppose Arcturus Mengsk and the Terran Dominion, and their campaign operations form the central perspective of StarCraft II: Wings of Liberty. The group uses the battlecruiser Hyperion as its main mobile base during that campaign.

The name is distinct from the Sons of Korhal, the revolutionary organization Mengsk led before establishing the Dominion. Raynor once fought alongside the Sons of Korhal, but he broke with Mengsk after becoming disgusted by Mengsk's methods and his abandonment of Kerrigan. The Defenders of Man are a later faction connected to StarCraft II's broader story, not Raynor's own rebel force.
