Background

The United Nations Space Command was formed by the United Nations during the Interplanetary War. After the eventual UNSC victory, overpopulation on Earth became a major issue in the early 22nd century. This issue was resolved and disaster averted by colonizing and building vast cities on other planets in the Orion Arm of the galaxy, the Inner Colonies and later the Outer Colonies.

The UNSCs defensive military force is the UNSC Defense Force (UNSCDF), and consists of the UNSC Air Force, the UNSC Army, the UNSC Marine Corps and the UNSC Navy. ^[3]

The UNSC is run by the UNSC Security Council, under the jurisdiction of the Security Committee and is Earth's main military force, most recently fighting the Covenant. The Navy houses the divisions of UNSC Marines (including the special forces branch of the UNSC Marines known as Orbital Drop Shock Troopers more commonly know as ODSTs or "Helljumpers"), Office of Naval Intelligence (ONI), and the Fleet. The UNSC was originally designed to keep the peace, order, and control, thus serving as an executive governmental branch between neighboring planets and star systems. When certain rebellious factions began to rise in the late 2510s, the UNSC was forced to police its colonies tirelessly to keep privateers and pirates from raiding the colonies and any UNSC ships.

The Unified Earth Government and the United Nations still exist and operate the UNSC. It acts as a democratic world government, where all the participant nations share the same legal system as the UNSC and act as smaller parts of the greater whole.

It should be noted that the UEG's specific functions, legal makeup and legal boundaries as they relate to the CAA and UNSC are not yet known in detail.

The United Nations Space Command Flag is described as "...a blue field with stars and Earth in the corner." ^[4]
