Galactic Republic Space Command (Earth-2042)

"By Sea, By Land, By the Stars."

- Motto

The Galactic Republic Space Command (GRSC) was the military, exploratory, and scientific agency of the Galactic Republic, which acted as the emergency governing body of the Republic at large during the Clone Wars. The GRSC was formed in the 1423 BBY, a time when remnants of old cultural ideologies clashed for supremacy in the Coruscant system.

In an attempt to help end the long-running Insurrection, the Galactic Republic secretly commissioned the ORION Project and later the SPARTAN-II Program, which created elite supersoldiers to combat the Insurrectionists. When the Republic-Covenant War began and the Covenant began ravaging the Colonies, these Spartans became the Republic's best hope against the hegemony. A decade later, when the Clone War began and the Confederacy of Independent Systems made their move, the GRSC, which had been mired in controversy, became once again the Republic's greatest protector. This allowed Supreme Chancellor Palpatine to override the Galactic Constitution to be given free emergency powers and establish himself as a dictator and the Systems Alliance as the Republic's primary government.

The GRSC Armed Forces initially consisted of over a million enlisted officers, Marines, pilots and other specialists before its force became consisting populated by clone troopers; genetically identical soldiers cloned from a Human template, outfitted with armor, weapons and gear, and programmed for absolute loyalty to the Galactic Republic. Following the end of the Interplanetary War, the Galactic Republic Space Command represented the evolution of galactic warfare at the time of its introduction on Geonosis, and was instrumental to Sith Lord Darth Sidious' secret plot to take over the galaxy.
