The UNSC is the armed forces, exploratory and scientific branch of the Unified Earth Government, as well as emergency government in times of war. It was formed in the 22nd century to combat communists and evolved to become the defenders of humanity. The UNSC is commanded by FADM Singile (Chief of Naval Operations), Adml. Osman (Chief of Naval Intelligence), Gen. Nicholas Strauss (Army), Gen. Harland (Marine Corps) and Gen. Amemiya (UNSCAF).

Branches and organizationsEdit

  • UNSC Navy - The Navy is essential to the UNSC's ability to maintain her colonies and defend them. While no longer the largest of the factions it still has power projection in both space and the seas. A large chunk of funding goes here. In addition to the space forces, the UNSC Navy also maintains traditional waterborne navy.
    • UNSC "Coast" Guard - Created with the appearance of the UCR under the Navy. They maintain a smaller, separate fleet of older ships to protect the UEG's EEC , preventing piracy, aiding ships in distress and collecting tarriffs.
    • UNSC Fleet Auxillary - The resupply arm of the UNSC military, delivering food, fuel, ammo and equipment for the Navy.
    • Office of Naval Intelligence - The Spooks. In charge of intelligence, propaganda, espionage, experiments and research - even if it means getting some hands dirty and a few people mysteriously disappearing.
  • UNSC Air Force - Division within the UNSC. It is tasked with organizing aerial operations, conducting tactical strikes and bombing runs, providing close-air-support for infantry forces, and transportation of UNSCDF personnel. Again they get a significant chunk of money for their projects.
  • UNSC Army - The only branch of the UNSCDF mainly in charge of primarily ground based operations, including garrisons and occupation. While fighting alongside the Marines, few credited them for their service. They also tend to fight for scraps of funds.
  • UNSC Marines - The branch of the UNSCDF in charge of land based operations using the Navy to get from point A to Z and provide security for Naval installations.
