Orion can be more than one thing:
- Arm of Orion, the rebel faction of former USIF soldiers presumed lost.
- Orion's Spear, the faction of brutal supersoldiers turned traitor and dedicated to destroying all they once fought for.
- HKD10 "Orion" is a kinetic machine gun the Arm used as a counterpart to the R-KMG7A "Ripsaw".
