The United Nations Space Command (UNSC) is the military, exploratory, and scientific agency of the Unified Earth Government. The UNSC was formed in the 22nd century, a time when remnants of old cultural ideologies clashed for supremacy in the Sol System. The UNSC served mainly as overseer of United Nations military operations in space. After initiating massive militarization propaganda throughout its off-world colonies, through the UNSC, the UN defeated communist and fascist forces in a conflict generally known as the "Interplanetary War", which consisted of several side-battles that took place on Mars, the Jovian Moons and the South American rainforests. Although the Interplanetary War brought a great deal of suffering to both the colonial population and the residents of Earth, it also united humanity's military forces into a common armed force by the end of the 22nd century.

Prior to the Covenant attack on Harvest in 2525, humanity was in chaos. Battles on multiple fronts and planets evolved from a group known as the Insurrectionists who wanted independence from the Unified Earth Government. The UNSC, more specifically, the UNSCDF, fought constant battles against the Insurrectionists. In an attempt to help end the long running war against the rebels, the UEG commissioned the ORION Project (also known as SPARTAN-I project) and later the SPARTAN-II Program, which created elite super-soldiers to combat the separatists and the insurrections they spawned. When the Human-Covenant War began and the alien invaders began decimating the Outer Colonies, these Spartans became humanity's best hope against the technological superiority of the aliens. When the war began, the UNSC became humanity's greatest protector.

This fact allowed the UNSC to override civilian rule and establish itself as humanity's primary government. Although the Unified Earth Government was more open to step down, the Colonial Administration, the arm of the UEG ruling over the colonies, resisted the UNSC's rise to power, and was thus stripped of its power.

By 2552 A.D., Earth was the last remaining major human bastion; and fell under attack by the Covenant forces. The Human-Covenant War finally came to an end after a UNSC and Covenant Separatists force eliminated the Covenant leadership and destroyed the Flood threat.

By the time the war began, humanity, and thus the UNSC, had reached Tier 3 of the Forerunner civilization achievement rank system. Humanity's rank continued to rise due to the capture of Covenant technology and equipment, which was studied and adapted for human needs. The very best and cutting edge of UNSC equipment was supplied to the SPARTAN-II project, and later less expensive but still cutting edge technology was given to the Spartan III's. One such example of innovative human technology is the energy shielding adapted and improved for use on the MJOLNIR armor.


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

The UNSC's 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.


Interplanetary WarEdit

The UNSC has its roots in World War I, which led to the creation of a League of Nations. The League of Nations led to the formation of the United Nations after World War II. The UNSC was actually formed and fashioned as the result of a series of brutal conflicts across the Solar System and humanity's space confines between 2160 and 2164, most prominently among them the Jovian Moons Campaign, the Rain Forest Wars, and a series of battles on Mars.

The United Nations Space Command, as organized and orchestrated as it seems, is actually an emergency military government formed in such strife. These encounters were centered around UN clashes with dissident political movements, the most important of which were the "Koslovics" and the "Frieden". More specifically, the Frieden movement was a fascist organization based on the Jovian Moons, though they received backing from some corporations operating in the United German Republic on Earth, while their ideological opponents, the Koslovics, formed a Marxist-Leninist group centered around the leadership of Vladimir Koslov.

The war began with an attack on United Nations colonial advisers on the moon of Io, one of the moons of Jupiter, but would spread to Mars and parts of South America in the Rain Forest Wars. These events culminated in a UN build-up in the mid to late 2160's, which would result in the UN establishing a unified military and a permanent Unified Earth Government as an ultimate power to lead the human race by 2170.


The four-year long war put the spotlight on problems facing the overpopulated planet, and the Rain Forest Wars also exacerbated the problems relating to food distribution. The ensuing famine and societal problems related to the post-war population boom providing the spark to change the political nature of governance on Earth and elsewhere, leading to the political system seen in the 26th century.

These pressures also helped make space colonization seem more attractive in later centuries, as the Unified Earth Government would sign off on a colony ship program that was revealed in 2310 to ease the burden on the ailing home world. This would not have been possible without the invention of the Shaw-Fujikawa Translight Engine in the late 2200s, which allowed the ships to travel far greater distances than ever before by means of allowing access to Slipstream space.

It took 52 years before the first colony ship, the Odyssey, was launched, and what became the so-called Inner Colonies were not fully colonized until the end of the 24th century. The apex of human colonization would come in 2492, when more then 800 worlds were inside UNSC territory and a handful of them were under development or had already developed into colonies. By this time, a ring of Outer Colonies was providing the UEG with the raw materials that made the macro-economy work; the political power, however, remained with the aforementioned Inner Colonies. The massive difference in wealth distribution and political power, which became a hallmark of humanity by this period, led to new threats of secession from the outer ring. Fearing the consequences of the breakup of the interstellar empire and seeing the benefits of avoiding all-out war to defend their hold on the colonies, the Earth government would embark on the SPARTAN-Is, the predecessors to the SPARTAN-II program in 2491, beginning with the ORION Proect.
