United Nations Space Command

The United Nations Space Command (UNSC) is the scientific, exploratory and military arm of the United Nations, Colonial Administration Authority and the Unified Earth Government that controls and administers that authority. The UNSC's military arm is called the United Nations Space Command Defense Force, used to protect human colony worlds and engage threats to the UNSC.

During the First and Second Battle of Earth, the UNSC fought the Covenant on Earth to keep Humanity from going extinct.

Background
The UNSC was formed by the United Nations when over-population on Earth started becoming a problem in the early 22nd century. They sorted the problem by colonising other planets in the Orion Arm. The UNSCDF is run by the UNSC Security Committee and is Earth's main defense against the Covenant. The Navy houses the divisions of Marines (including the Orbital Drop Shock Troopers), and Office of Naval Intelligence, and the fleet. Originally designed to keep the peace 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 to keep privateers and pirates from raiding them. After Harvest, a colony planet, was destroyed, one badly damaged UNSC ship returned to tell the tale of monstrous alien ships that utterly destroyed the colony. The UNSC doubled its shipbuilding to bolster themselves against the Covenant, but it was useless, for the Covenant's technology was far superior to mankind's. The UNSC fortified major positions such as Reach, the UNSC's main shipyards and command center, and Earth. The war finally ends with help from Covenant separatists that seceded during the Covenant Civil War. The war has seen the Arbiter and his people, the Elites, join forces with the UNSC against the remainder of the Covenant in a desperate, yet successful fight for survival.

As of at least 2552, the UNSC has apparently assumed the governing duties of the Unified Earth Government as an emergency military government, in the face of overwhelming Covenant incursions. It is unknown whether the UEG still exists, what it does, or whether it will return to power now that the Human-Covenant War has ended.

There are several breakaway factions opposed to the Government and UNSC as well, including the United Rebel Front.

The UNSC Flag is described as "...a blue field with stars and Earth in the corner." .

It should be noted now 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.



A Short History
The United Nations Space Command was formed as the result of a series of brutal wars across the Solar System between 2160 and 2164, most prominently among them the Jovian Moons Campaign, The Rain Forest Wars, and a series of battles on Mars. These conflicts 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 UN Military Advisers on the moon of Io, but would spread to Mars and parts of South America in the Rain Forest Wars. These events culminated in a large UN buildup in the 2160s, which would change the UN from a largely diplomatic organization to a permanent military power; the war's consequences also helped make way for a unified government seated on Earth 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 related to food distribution. The ensuing famine and societal problems related to the post-war population boom provided the impetus to change the political nature of governance on Earth and elsewhere, leading to the political system seen in the period of the Halo games.

These pressures also helped make space colonization more attractive in later centuries, as the government would sign off on a colony ship program that was revealed in 2310 to ease the burden on the ailing homeworld. This would not have been possible without the invention of the Slipspace drive in the late 2200's.

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 UNSC colonization would come in 2492, when over 800 worlds were under human control and were at various stages of development. By this time, a ring of Outer Colonies was providing the UN 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 the humans' civilization 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 UNSC would embark on the predecessors to the SPARTAN-II program in 2491, beginning with the ORION Project.

The Human-Covenant War
2525 marked a pivotal turning point in human history. it would mark the beginning of great technological advancement, and the unification of a divided and fractured human race, and the first contact of humanity and an extraterrestrial intelligence, the Covenant. It would also see the lot of the UNSC's 800 colony worlds destroyed, and billions of colonists slaughtered by orbital plasma bombardment and planetary invasion.

Thus began the Human-Covenant War.

Stemming from the chance encounter of humanity and Covenant forces at Harvest, first contact was less than peaceful. A less aggressive meeting between representatives of the two factions met on the fields of Harvest, but peaceful meeting soon turned into a blood bath, with the Covenant claiming the planet for the numerous "Forerunner relics" present, slaughtering much of the colony's population.

On October 7, a scout ship, Argo, was sent to investigate the cessation of communications between Harvest and the rest of the UNSC. The scout ship was also lost. It discovered that everything on the planet had been completely incinerated, and the surface had been melted down to glass. In orbit around the remains of the colony world was a single alien ship which proceeded to attack the battle group, destroying all the ships except one. Intercepted communications identify the enemy as The Covenant, a caste-driven, theological organization made up of several alien species. The message "Your destruction is the will of the gods... and we are their instrument" was broadcast in perfect English. .

Since the later Battle of Harvest in 2531, which retook the planet in a symbolic "victory" for humanity, the humans' grip on their territories declined significantly in the course of their struggle. Of the more than 800 colony worlds, the Covenant has managed to capture and glass nearly every, if not all Outer Colonies and a significant number of the Inner Colonies. The UNSC Navy, Marine Corps, Army and Militias, outnumbered and outgunned, have managed to slow down the Covenants inexorably progress through former human space, but the situation is drastic. In desperation, HIGHCOM orders a high-risk Op, sending the Spartan-II super soldiers, the best soldiers ever fielded by humanity, to insert into Covenant space, capture a high-ranking Prophet, and return to UNSC space in an attempt to ransom for a truce. Before the operation begins, the Covenant find and destroy the planet that would have served as its launching pad, Reach, killing most of the Spartans and a large portion of the UNSCDF.

By October of 2552, the Covenant have haphazardly discovered the position of the human homeworld, Earth, and send a preliminary task force there, believing it to be the location of the Ark, an ancient Forerunner relic. They encountered staunch resistance, and are initially fended off. Further complications arise from the political and religious crisis that emerges in the wake of a UNSC operation to assassinate a Prophet, and the secession of the Sangheili from the hegemony, leading to the Covenant Civil War, further throwing the Covenant into chaos. nevertheless, by November what is left of the Covenant Loyalists have subjugated large parts of Earth, devastating much of the planet. Only its retreat through a Forerunner portal in Africa, and the arrival of the Sangheilian Fleet, stop the utter destruction of the UNSC and Earth itself.

The UNSC and Sangheili forces launch a joint operation to destroy the Covenant Loyalists once and for all at the Ark, stopping the installation from firing The Halo Array, killing the Covenants last remaining leader figure, and destroying the bulk of the Loyalists remaining forces. On March 3, 2553, the Human-Covenant War officially ends in a victory for the UNSC and the Sangheili, but at a high price: most Outer Colonies and a chunk of the Inner Colonies were burned, and the post-war population of Earth is less than 200 million. It is presumed that untold billions of humans have been killed from 2525-2553.
