From the 2190s through the 2560s, this was the dominant governing body of the interplanetary and interstellar colonial efforts of the humans of Earth.

Introduction:

Per Mare, Per Terras, Per Constellatum.
— Motto (Latin for “By Sea, By Land, By the Stars.”)[2][3]

The United Nations Space Command (UNSC) is the military, exploratory, and scientific agency of the Unified Earth Government which acted as the emergency governing body of the human race at large for a time.[4] 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 Frieden and Koslovic insurgent forces in a conflict 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 most of humanity’s military forces by the end of the 22nd century.[5]

Prior to the Covenant attack on Harvest in 2525,[5] the UNSC was stretched across human space. The most urgent concern was to contain the spread of the Insurrectionists, a violent resistance movement consisting of colonists who wanted independence from the Unified Earth Government. The UNSC fought constant battles in a loosely-defined civil war known as the Insurrection. In an attempt to help end the long-running war, the UEG commissioned the ORION Project and later the SPARTAN-II program, which created elite supersoldiers to combat the Insurrectionists. When the Human-Covenant War began and the alien invaders began destroying the Outer Colonies, these Spartans became humanity’s best hope against the technological superiority of the hegemony. When the war began, the UNSC, which had been mired in controversy, became humanity’s greatest protector. This 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 Authority, the arm of the UEG ruling over the colonies, resisted the UNSC’s rise to power, and was stripped of its influence.[4]

Near the end of the year 2552, Earth was the last remaining major human bastion: it too fell under attack by the Covenant. Near-crippled in the aftermath of the Fall of Reach, the UNSC dedicated most of its remaining assets to the defense of the Sol System. The Human-Covenant War finally came to an end after the UNSC and the Fleet of Retribution eliminated the Covenant leadership and destroyed the Flood threat. In its aftermath the UNSC has upheld its alliance with the Swords of Sanghelios and eventually ceded political power back to the UEG. The UNSC is now experiencing a resurgence as it rebuilds humanity’s wartorn domain and moves to reestablish itself as a major power within the Orion Arm.

Mission

Though the official UNSC mission statement has been amended since it was established in 2163,[1] the UNSC’s statement of function can be summarized in two points:

  • Uphold and advance the policies of the Unified Earth Government.[1]
  • Ensure the safety and security of Unified Earth Government territories, possessions, and areas vital to its interests.[1]

Predecessors

The United Nations Space Command has its roots in World War I, a conflict which led to the creation of the League of Nations in 1920. Following World War II in 1945, the largely ineffective League of Nations was replaced by the United Nations, creating for the first time in human history a political and military entity that could administrate worldwide economic, social and military matters such as operations and campaigns aimed at providing humanitarian aid and global military intervention with the objective of preserving peace in unstable regions.[5]

Interplanetary colonization

Main article: Human interplanetary colonization

As space exploration progressed in the 21st century, colonization operations required international cooperation and assistance in order to effectively conduct territorial expansion throughout the Solar System. The International Society of Civil Engineers was formed at this time (2021), an organization that contributed immensely to furthering the quality of space engineering.[6]National-conservative philosophies slowly made way for progressive, international globalization to take effect.[5] An imperative change in worldwide government was necessary to accommodate space colonization demands, which the only global administration organization humanity could rely on. National governments began to lose their overall authority on a global scale, while the influence of the United Nations increased.[7] In 2075, the United Nations created the Unified Earth Government, then as an international think tank tasked with solving the challenges of interplanetary expansion and governmental unification.[8]

By 2080, human colonization of the Solar System was fully underway.[9] Offering reasonable living conditions and a physical composition similar to that of Earth, Mars was the first planet to be colonized and soon became a major center of science and industry.[10] Settlements were also established on Luna, the asteroid belt, as well as the Jovian Moons, the latter sponsored in large part by Unified German Republic corporations. Advances in terraforming technology enabled the reshaping of many of the Solar System’s formerly inhospitable worlds into sustainable earthlike environments.[11]

Human settlement of the Solar System was initially driven more by commercial goals than the comparatively modest programs run by Earth’s nation-states. Corporations sought to escape the bureaucracy and laws of national governments and the United Nations that interfered with their operations on Earth. While this resulted in many scientific and technological developments, it also bred suspicions about the ethics of the offworld corporations’ activities. In response, the UN enacted the Genetic Rights Act in 2165 in order to ensure the fulfillment of basic human rights in humanity’s expanding domain.[11]

Political conflicts (2160-2170)

As the UN’s campaign of centralization and globalization progressed and increasingly more space settlements were being established, ideological political and economic tensions did not disappear with them. With the transition being made from Earth-based capitalism to post-industrial space capitalism, elements on the extreme fringe of the political left-wing saw a rebirth of doctrinal origin, and revolutionary ideas of change once again took the form of military organizations.[5]

One of these ideological resurgences centered around Russian-born revolutionary Vladimir Koslov, who proceeded to form a neo-Communist guerrilla armed force named after himself; the Koslovics. The new group of communists aimed to dismantle capitalist systems and corporate power on Earth and in newly-occupied space territories, putting a particularly strong emphasis on liberating orbital installations and orchestrating so-called “workers’ crusades,” or armed campaigns against their foes on the opposite end of the political spectrum.[5]

The Frieden military movement, based in the Jovian Moons and sponsored by corporate powers in the Unified German Republic, reacted once this upsurge of communism became obvious and Koslovic revolutionaries began attacking their infrastructure. Considered a Fascist movement, the Friedens’ ardent anti-Koslovic sentiments convinced them to adopt revolutionary ideals as well. Among their primary objectives was gaining corporate independence by seceding from UN colonial administration and establishing a self-contained Jovian state. Frieden propaganda claimed that in order to reach a peaceful (as their German name suggests) and independent Jovian nation, the UN, an advocate of internationalism, was to be driven out of the Jovian Moons and destroyed around the Solar System, including on home ground.[5]

Earth’s still-disparate, United Nations-aligned national militaries soon found themselves pinned from the extreme left-wing and extreme right-wing alike. These political tensions would soon lead to a final face-down between fascism, communism, and international representatives of democracy throughout various colonies, space environments, and national territories.[5]

Jovian Moons Campaign

Main article: Jovian Moons Campaign

Despite Frieden war-mongering propaganda, the Jovian Moons were still held under tight UN control up to 2160. In March of 2160, the Frieden’s led its first revolutionary assault against UN authority, attacking UN Colonial Advisors on the moon Io and giving rise to political reactions on Earth. International UN military forces deployed to the Jovian system, engaging the fascist rebellion in three months of battle.[5]

The Jovian Moons Campaign heated tensions within faltering national governments of Earth, paving the way for wars-by-proxy between military corporations, national armies, and political renegades as governments that sponsored colonies in the Solar System responded to Frieden-UN ballistic exchanges and initiated military campaigns of their own, either for their own benefit, or for the benefit or their respective colonies. In a vicious chain reaction, politics on Earth took a downturn to arms mobilization.[5]

Rainforest Wars

Main article: Rainforest Wars

Following a relatively blurry outcome in the Jovian Moons, Koslovic, Frieden and UN forces prepared for an engagement in South America in the year 2162, one of the most fertile and economically-promising regions of Earth. Presumably in an attempt to gain some material goods from industries in South America, the two military juntas assaulted each other and the UN troops scrambling to defend home territory, culminating in what is now symbolically known as the Rainforest Wars.[5]

The conflict in South America resulted in an enormous amount of human casualties, especially in the lines of infantry on all three sides, due to difficult fighting conditions among the continent’s numerous mountain ranges, rainforests, wildlife and volatile weather. Real consequences of the conflict, however, consisted of severe starvation and famine on an international scale – which is reason to believe the UN was no longer acting solely as a military defense force in the face of political extremists, but also as a primary provider of starvation relief – along with a further tensing of military conflicts already raging through the Solar System.[5]

Advent of the UNSC

Main article: Mars Campaign

In the most spectacular offensive since the start of the bloody tripartite war, UN command adopted a military strategy long-forgotten throughout the peace-dominated period prior to the outbreak of the Jovian Moons Campaign in 2160 – the “Blitzkrieg”-style lightning ground assault. After capturing both Frieden and Koslovic forces on Mars, the UN delivered the first space-deployed contingent of the newly-established Marines in December of 2163 on a mission to crush communist infantry encampments in the basin of Argyre Planitia, marking a turning-point in space warfare through dedicated deployments of Marine forces in ground assaults and ship-boarding operations that would follow during the war.[5]

The offensive was an incontestable success for the UN side. As a result, military theory and strategy implemented the use of Marines in high-priority missions as a baseline for successful operations, especially within the context of larger conflicts.[5]

However, the most important consequence of the anti-totalitarian campaign was of both political and military nature. The United Nations itself did not control a dedicated space military prior to the Mars Campaign, a lacking element which it would replace with a special emergency military force that would come to represent humanity’s overall military might. In the wake of the success of the UNSC Marines on Mars, the UN used its growing influence to not only take control of Earth’s national governments, but also absorb Earth’s national military organizations into a single, organized force; the United Nations Space Command was created.[5]

Interplanetary War

Main article: Interplanetary War

As of 2164, psychological results of the campaign on Mars were formidable; civilian trust in the newly-formed UNSC military was boosted by massive televised propaganda, providing the UNSC with large waves of enthusiastic volunteers from all military services around the world. A sense of urgency, courage and hope helped UN forces scramble extraordinary divisions of Marines, infantry and fliers for a final campaign to annihilate remaining communist and fascist outposts and strongholds on Earth as well as throughout the inner planets and beyond Jupiter. The final campaign for peace lasted from 2164 to 2170 in a series of brutal crackdowns on Frieden and Koslovic hardliners. The result of this war gathered strong civilian support for some sort of powerful international military that could repel revolts and uprisings wherever they may occur. The UNSC emerged as the leading force to further those goals.[5]

UN victory

Almost paradoxically, the war formally ended where it had begun: in the Jovian Moons. The Callisto Treaty was signed in 2170 by commanders of Koslovic and Frieden forces in the presence of UN colonial authorities, definitively ending the 10-year-long conflict with a victory of UNSC forces and democratic leadership.[5]

2170 saw the creation of the first multinational and multicolonial representation of democracy in outer space. Faced with concerns of overpopulation and starvation on Earth, consequently coupled with a looming destabilization of capitalist economy, the Unified Earth Government—up until then lacking concrete power—was formed into a full-fledged governing body in a time of cultural and military reconstruction.[5]

The brutal ten-year-long war put the spotlight on problems facing the overpopulated Earth, and the Rainforest Wars also exacerbated issues relating to food distribution; this, along with the UN overmilitarization that occurred during the war, presented immediate problems for the postwar United Nations Space Command. The ensuing famine and societal problems related to the postwar population boom provided the spark to change the political nature of governance on Earth and elsewhere, leading to widespread political reform.[5]

The Colonial Era

The pressures engendered by the Interplanetary War made space colonization seem more attractive in subsequent centuries, and the Unified Earth Government would sign off on the first large-scale interstellar colony ship program that was revealed in 2310 to ease the burden of an overpopulated Earth. This would not have been possible without the invention of the Shaw-Fujikawa Translight Engine in 2291, which allowed the ships to travel vast distances within a reasonable time by opening portals into Slipstream space.[5] At the same time, the UEG established a separate colonial governing body known as the Colonial Administration Authority as well as the Colonial Military Administration, a dedicated military force to police the colonies.[12]

In 2362, the first colony ship, the Odyssey, was launched, beginning the period of human history later known as the Domus Diaspora.[13]This initial colonization effort was concentrated in the Epsilon Eridani system, which would later become one of the centers of humanity’s interstellar empire.[14] Vast numbers of citizens and soldiers elected to travel to these new colonies, stabilizing the overpopulation problem on Earth and giving the military new tasks to handle. As the first colonists are stringently selected, the Inner Colonies eventually formed an elite society of the best physical and mental human specimens. A core ring of 210 Inner Colonies were not fully developed until the end of the 24th century.[5]

The apex of this colonization movement would come in 2492 when more then 800 worlds were inside UNSC territory, many of them targeted for human habitation. These settlements ranged from fairly well-tamed planetary strongholds to tiny hinterland settlements. During this period, the planet Reach (orbiting Epsilon Eridani, right on Earth’s metaphorical doorstep) became the UNSC’s primary naval yard and training academy. Reach was a major producer of warships and colony vessels, as well as a training ground for covert operatives and Special Forces.[5]

Over the course of humanity’s interstellar expansion, a number of alien artifacts were discovered; while unknown at the time, these were the works of a long-vanished civilization known as the Forerunners. However, virtually all of these findings were discreetly concealed by the UNSC’s Office of Naval Intelligence, which exerted virtually complete control over the research and information flow about xenoarchaeological discoveries. A noted example of this is Onyx, originally surveyed as an ideal world for human settlement but declared off-limits by ONI due to the alien technology discovered there.[14]

The Insurrection (2494-)

Main article: Insurrection

By the final decade of the 25th century, a chain of Outer Colonies was providing the UEG with valuable raw materials; the political power, however, remained with the aforementioned Inner Colonies. These differences in wealth distribution and political power, led to new threats of secession from the outer territories. Over time, ideological and political causes resulted in many of the Outer Colonies engaging in open rebellion. A series of brushfire wars across human space sprang up, with hundreds more threatening to erupt as well. By 2511, UNSC estimates, largely based upon the projections of Dr. Elias Carver, put massive, overwhelming, and uncontrollable rebellion at less than twenty years away.[5]

Military conflicts began disrupting UNSC authority in the Outer Colonies where several uprisings among working-class agriculturalists and other social classes grew unhappy with the UNSC’s largely inconsiderate governance. This unrest gave rise to the Insurrectionist movement, a loose collection of violent colonial separatists with the shared goal of liberating the Outer Colonies from the Unified Earth Government’s influence.

Spartans

Fearing the consequences of the possible breakup of their fledgling interstellar empire, while wishing to preserve as much infrastructure as possible, the United Earth Government would embark on a series of covert efforts to quickly and quietly deal with insurrections without incurring massive civilian casualties.[5]

Before the UNSC expanded its forays into biological augmentation to create successful Special Forces programs in the 26th century, the Colonial Military Administration experimented with a prototype Special Forces project in the 24th century that tested the effects of bioaugmentations on Marine Corps and Navy personnel. The experiments proved ineffective and were formally canceled as a result, marking the first attempt to create a specialized force of covert-warfare operators in response to insurgent outbursts within the domain of the Unified Earth Government.

Due to increasing risk of insurrectionist activity in the late 25th century, the UNSC’s Office of Naval Intelligence conceived a project to train Special Forces soldiers in counter-insurgent and counter-revolutionary warfare. The ORION Project, retroactively termed as Spartan-I, was an Naval Special Warfare program, overseen by the CMA, created to train special advanced warfare squads to combat the Insurrection. They became experts in counterinsurgency operations, assassinations, raids, and eliminating high value targets—all considered black operations.[15] However, expectations for the new soldiers were not met, and the project was deactivated in 2506, and all members reassigned to other Special Operations units.[16] In the coming years, ORION’s methodologies would be uses as basis for a reform in the Orbital Drop Shock Troopers,[17] the most famed special operations force of the UNSC Marines.

Several years later, ONI’s alarming projections on colonial instability prompted them to initiate a second generation supersoldier project which would come to be known as the SPARTAN-II program. Partly informed by the pioneering efforts of ORION with new methodologies conceived by Dr. Catherine Halsey, the new program introduced highly unethical aspects such as the covert conscription of mentally and physically gifted children who would be molded into the perfect instruments to quell insurgent leadership and thus prevent the predicted scenario of indefinite all-out war. Physically augmented and equipped with state-of-the-art MJOLNIR powered armor, the Spartan-IIs would prove to be the most effective soldiers fielded by the UNSC, although not in the role they were originally intended for; the attack of the genocidal Covenant quickly saw the Spartans reallocated to combat the new enemy.[18]

During the Covenant War, the success of the Spartan-IIs would convince the ONI leadership to use similar methodologies to create hundreds of supersoldiers in the SPARTAN-III program. Despite various refinements in their training and augmentation processes, most of the Spartan-IIIs would be less well-equipped than their predecessors for budgetary reasons, and the majority of them would ultimately perish on strategically important, high-risk deployments.[19] Following the end of the war, the SPARTAN-IV program marked a return to ORION’s recruitment protocols, drawing candidates from the UNSC’s extant military forces; additionally, technological advances and the relegation of equipment manufacturing to the private sector allowed each operator to be issued with the previously prohibitively expensive Mjolnir armor. With Spartans being created in increasing numbers, their presence across UNSC-controlled space would become far more established and publicized in the years that followed than ever before.[20]

Human-Covenant War

Main article: Human-Covenant War

The Covenant invade a population center on a human world.

2525 marked the most important turning point in human history. It would mark the beginning of the great technological advancement, the unification of a divided and fractured human race, and the first contact between humanity and (a publicly-acknowledged) extraterrestrial intelligence; the Covenant. It would also see a majority of the UNSC’s colony worlds destroyed, with billions killed by orbital plasma bombardment, a technique latter known as glassing. The most important war in the history of the human race began with a disastrous first contact at the distant colony of Harvest.

By this time, the UNSC overrode the UEG, and thus became the central civilian authority throughout its territory and Earth itself. Although the central government was more willing to step down given the magnitude of the crisis, the Colonial Administration Authority was far more reluctant. As a result, the UNSC stripped it of most of its power. By the middle to late stages of the war, the government of humanity could be accurately described as an “emergency military” force.

First contact

Main article: First Battle of Harvest
Admiral Cole's victory at Harvest.

Stemming from the chance encounter of human and Covenant forces at Harvest, the first contact made between humanity and the Covenant involved the ship Minor Transgression, and was less peaceful than the second contact made between the two factions. A meeting between representatives of the two factions took place on the fields of Harvest, but the attempt at diplomacy soon turned into a bloodbath. The Covenant claimed the planet for the numerous “Forerunner relics” their luminaries had detected, and slaughtered most of the colony’s population.[5] The vast majority of the Covenant remained unaware that the humans they were sworn to annihilate, were in fact the very Reclaimers (mistranslated as “Reclamation”) their ancient texts spoke of.[21]

On April 20, a scout ship, the CMA sent in a scout ship, the Argo, to investigate the cessation of communications between Harvest and the rest of the UEG’s colonies. Before being destroyed by Covenant forces, it discovered that the planet had been incinerated, and its surface covered by fields of magma. Soon after, Battle Group 4, consisting of the frigates CMA Arabia and Vostok and the destroyer CMA Heracles, were sent to investigate. On October 7, the battle group dropped out of Slipspace and to Harvest. In orbit around the remains of the colony world was a single alien ship which proceeded to attack the battle group, destroying them all except one. Intercepted communications identified 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.[22] The war for mankind’s very survival had begun.

Since the later Second Battle of Harvest in 2526, where an enormous human fleet led by Vice Admiral Preston Cole barely won against a single Covenant ship in a symbolic “victory”, the UNSC’s grip on their territories declined significantly. While the UNSC fought a formidable defensive action against the Covenant’s onslaught, the Covenant’s technological superiority in space overwhelmed humanity’s naval defenses. Over the next 27 years, the Covenant had managed to destroy nearly all of the Outer Colonies, and a portion of the Inner Colonies.[5]Recognizing that it was fighting a losing battle against a superior enemy, the UNSC adopted and enforced the Cole Protocol, drafted by Admiral Cole to ensure that the Covenant never learned the location of Earth as the war continued to spread into human space.

The UNSC’s military victories against the Covenant were few and far between, with Admiral Cole winning a decisive victory against the Covenant at the Battle of Psi Serpentis in 2543, destroying an entire enemy fleet at the cost of his own life. Behind the scenes, humanity began to extensively reverse-engineer technology recovered from both the Forerunners and the Covenant in a bid to bridge the gap between the Covenant and humanity’s technological advancement. The deployment of the Spartan-II supersoldiers proved devastating to the Covenant and enabled the UNSC to stave off several major Covenant offensive operations. However, the Covenant’s encroachment of human space continued largely unabated, and the ongoing war of attrition took a toll on the UNSC’s offensive capability as the threat to Earth’s survival drew closer.

RED FLAG and Halo

UNSC Pillar of Autumn arrives at Installation 04.

By 2552 the UNSC, outnumbered and outgunned, had nonetheless managed to slow the Covenant’s inexorable progress through human space. However, the situation remained dire. In desperation, HIGHCOM ordered a high-risk operation, sending the SPARTAN-II supersoldiers to insert into Covenant space, capture one or more high-ranking Prophet, and return to UNSC space. With such valuable hostages, the UNSC would then attempt to ransom these leaders for a truce. Before the operation began, the Covenant found and destroyed the fortress world of Reach, destroying a large portion of the UNSC’s military forces, inadvertently stopping the operation and, seemingly, killing most of the Spartans.[5]

A single ship, the UNSC Pillar of Autumn managed to escape the planet, with one active Spartan on board; Master Chief John-117. The ship followed coordinates derived by the AI Cortana to a Forerunner ringworld known as Halo Installation 04. There, John-117 encountered a parasitic lifeform known as the Flood, which Halo had been built to eliminate by destroying all life in the galaxy. John-117 destroyed the ring before it could be fired by detonating the reactors of the Pillar of Autumn. After hijacking a Covenant flagship, the Spartan reunited with the survivors from Installation 04 and the destruction of Reach. This small band of soldiers attacked a force of Covenant ships in Operation: FIRST STRIKE, one of the most successful UNSC operations against the Covenant in the entire war.

Final months

Main articles: Battle of Earth, Battle of Installation 05, and Battle of Installation 00

The UNSC Home Fleet engages the Covenant over Earth.

By October of 2552, the Covenant haphazardly discovered the position of the human homeworld, Earth, and sent a preliminary task force there, believing it to be the location of the Ark, an ancient Forerunner relic. They encountered staunch resistance, and were initially fended off. Further complications arose from the political and religious crisis that emerged in the wake of a UNSC operation to assassinate the Prophet of Regret, and the secession of the Sangheili from the hegemony, leading to the Great Schism. Overnight, the Covenant was thrown into chaos. Nevertheless, by November, the forces loyal to the Prophet of Truth had subjugated large parts of Africa and devastated much of the planet. Only the offensive led by Commander Miranda Keyes through the Forerunner portal uncovered in Africa, and the arrival of the Sangheili fleet prevented the eventual destruction of the UNSC and Earth itself.

The UNSC and their Sangheili allies launched a joint operation to destroy the Covenant once and for all at the Ark. Fighting against 3:1 numerical superiority in space, and even greater forces garrisoned on the Ark, the allies were able to stop Truth from firing the Halo Array. In addition, the Sangheili known as the Arbiter killed Truth, the Covenant’s last remaining leader, while SPARTAN-117 led the ground effort to destroy the Covenant’s remaining forces. On March 3, 2553, the Human-Covenant War officially ended in a victory for the UNSC and the Sangheili, but at a high price. Most major military outposts, along with countless colonies had been destroyed. Earth, despite the loss of billions to orbital bombardment, remained battered but standing. An estimated twenty-three billion civilians were killed between 2525 and 2553.[23]

Reconstruction and new conflicts

Main article: Post-Covenant War conflicts
For too many years, humanity was on the backfoot. Reacting to threats, rather than preventing them. Rest of the galaxy was bigger than us. Stronger than us. We were mice, hiding in the shadows, hoping the giants would not see us. No more. Humanity is no longer on the defense. We are the giants now.
 Captain Thomas Lasky[24]

The commissioning of UNSC Infinity.

The UNSC transferred its emergency governing functions back to the UEG on January 8, 2553, although this formal shift of power did not significantly diminish the UNSC’s practical authority.[25]

Since 2553, the UNSC has engaged in an extensive period of reconstruction in order to restore stability to the shattered remnants of its territory. The UNSC has moved to reclaim those worlds that were not completely destroyed during the Human-Covenant War. Former colonies such as Eridanus II,[26] Meridian and Draco III were resettled and became strategic staging points for humanity’s efforts to reunite its reach across space.[27] New planets such as Oban have also been colonized for the purpose of resettling the countless millions of refugees whose worlds were lost in the conflict. The UNSC also aimed to salvage any recoverable military assets lost during the war; paying companies such as Warner & Ives to recover slipspace drives from derelict vessels, and buying scrap from clearing house auctions, such as those in New Tyne on the planet Venezia.[28] The UNSC also maintains its earlier truce with the Swords of Sanghelios under the leadership of Arbiter Thel ‘Vadam. In 2553 the Joint Occupation Zones were created and are now governed by both the UNSC and the Sangheili, with former colonies such as Carrow now hosting new citizens from both sides. The UNSC has also established outposts around the Halo Array and other such Forerunner installations, which they closely monitor with the Sangheili. However, tensions remain as insurrectionist movements have grown in strength, with worlds like Venezia and Gao effectively having seceded from the UEG as recently as 2553.[29][30] In early 2553, the Office of Naval Intelligence began authorizing operations to sow dissent among the Sangheili, disregarding the alliance in the hopes of rendering them unable to fight should they become a threat again. These actions culminated in a civil war between the Arbiter’s forces and those who opposed the alliance with humanity.[31]

In spite of the catastrophic damage UNSC’s infrastructure and personnel suffered during the Covenant War, various secret projects initiated in the final years of the conflict enabled the UNSC to regain some degree of military power in the months after the cessation of hostilities.[32] To symbolize their newly regained strength, the UNSC adopted a revised version of its original emblem shortly after the war.[33] The UNSC’s rebuilding efforts were spearheaded by the symbolic commissioning of the UNSC’s most powerful warship, the UNSC Infinity, in February 2557. A dramatic modernization of the UNSC’s military assets has been ongoing, with new warships implementing both Covenant and Forerunner technologies for use against humanity’s enemies. While the reconstruction of humanity’s territories continued for many years after the end of the Covenant War, various Covenant remnants, most prominently a group led by Jul ‘Mdama, defied the truce that ended the previous war and arose to threaten humanity once again. In July 2557, the ongoing conflict against the new Covenant was joined by the Didact and his Promethean constructs due to an encounter on the shield world Requiem.[34] Following October 28, 2558 the UNSC was largely immobilized by the Created when Cortana and her Guardians took over Earth and most human colonies.[35] UNSC expeditionary forces that managed to avoid the Created’s Guardians were able to regroup with the Swords of Sanghelios on Sanghelios.[36]

By 2589, the former UNSC stronghold of Reach had been re-terraformed and resettled.[37]

Within HIGHCOM are a number of administrative commands, including PERSCOM, the Medical Corps, the Engineering Corps, Human Resources, and Astrophysics. Legal matters such as the issuing and enforcement of protocols are handled by the UNSC Judge Advocate General’s Corps. Research designed to improve the UNSC’s operations is carried out by the Internal Audit office.[39][40][41]

Also under HIGHCOM’s command are the UNSC Armed Forces, which handle the defense of UEG territory. Control is exercised through regional CENTCOMs, which have responsibility over certain areas of space.[42] The Armed Forces encompass the UNSC Army, the UNSC Navy, the UNSC Air Force, and the UNSC Marine Corps. The Navy houses the Marine Corps (including the special forces branch of the UNSC Marines known as Orbital Drop Shock Troopers), the Office of Naval Intelligence (ONI), and the Fleet. The Army and Air Force maintain garrisons on colony worlds. When certain rebellious factions began to rise in the 2490s, the UNSC was forced to police its protected colonies tirelessly to keep privateers and pirates from raiding the colonies and any UNSC ships. After 2553, Spartan Operations became the fifth and newest branch of the UNSC, responsible for command of special operations undertaken by the Third and Fourth generations of augmented soldiers.[43] The Spartans are the smallest operational component in the entire Armed Forces.

In an effort to maintain a constant supply of service members, the UNSC offers all able-bodied civilians the chance to enlist in various branches of the Armed Forces at automated UNSC recruiting centers. Numerous recruiting centers can be found throughout populated metropolitan areas.

The UNSC is also responsible for the overseeing and regulation of commerce throughout UEG space through the Department of Commercial Shipping. The UNSC also maintains the UNSC Symphony Orchestra[44] and the UNSC Jazz Band as ceremonial musical units.

 

Technology


Main articles: Human technology and UNSC Naval technology

By the time the Covenant War began, humanity, and thus the UNSC, had reached Tier 3 of the Forerunner civilization 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. Human technology was innovative, rather than reverse-engineered from Forerunner technology. This meant humanity remained flexible in their technical expertise, despite being hundreds of years behind the Covenant.[45] One such example of ingenuity was the energy shielding technology adapted and improved for use on the MJOLNIR armor.

 

Public Perception

We are UNSC! Today. Tomorrow. Forever.
— General Daniel Black quoting the poem “Forward Unto Dawn” in a UNSC recruitment video.[46]

The UNSC’s pre-Covenant War and wartime policies were viewed with hostility by the civilian populace, especially within rebel movements. Starting with the implementation of the Cole Protocol and martial law, the UNSC’s political takeover of the UEG and CMA branches and its generally authoritarian military policies championed over the course of the Human-Covenant War, the UNSC’s public image has been stained by rebel and civilian allegations of fascism, totalitarianism and oppression.[47][48]

These allegations are not completely baseless, considering most of this perceived UNSC-directed oppression lies with poor administration in the Outer Colonies, which has led to violent food riots perpetrated by proto-rebellious groups of dissatisfied colonial workers suffering from hunger and poverty at the hands of corporate planetary control.[49]

The UNSC also limits the freedom of the press to an extent, a measure put in place by ONI’s Section Two after the Inner Colony Wars—allegedly to prevent humanity from tearing itself apart from within.[50] ONI also exerts almost complete control over information about xenoarchaeological findings;[14] any scientists studying alien artifacts are drafted to serve under ONI’s supervision.[51] Nepotism is notably prevalent within the organization,[52][53] sometimes openly; Corbulo Academy of Military Science was based around the concept of training the offspring of high-ranked military and government officials as commissioned officers.[54]

 

Update:  Colonies

“The Inner Colonies consisted of the 210 planets which were colonized during the UEG’s first wave of colonial expansion between 2362 and 2390.”  There have been numerous colonization/expansion waves/campaigns since, the latest for this organization being, of course, in the post-war effort.

More than 800 colonized worlds is what is stated in one of the comic episodes (disclosure pieces) –as being the grand total before the latest war started wiping many of those back out, reducing them to their pre-colonization states.  There are a lot of inconsistent claims about the number of worlds the UNSC helped start and/or protect, ranging from a few dozen up to this higher limit.  This is likely a form of media-flooding to help protect these greatest assets.

It took 28 years (the span of the Human-Covenant War) for the Covenant to push the much-smaller UNSC back to the UNSC’s (210) Inner Colonies.  The Covenant is a force of many billions, its numbers never fully accounted for in any of the material/content/publications.  That should give you some idea as to 1) the effectiveness of the UNSC, and 2) the competency of the Covenant –or at least that they were overburdened/overtasked with other things during this time, such as scouting for artefacts and back-engineering / reactivating them beyond human-occupied Space.

Some outer colonies were never detected by the Covenant, thanks to (among other things) the Cole Protocol being followed; ships did not retreat to nearby worlds, and certainly not directly to the Sun solar system.  Even though this prevented emergency aid from being sent to some which were attacked/glassed, it spared many from otherwise certain attack/glassing.  It remains unknown/classified how communications and monitoring were maintained between UNSC colonies/worlds in such a way that the Covenant was not able to detect or trace those signals, which would have helped them find the remaining worlds.

~65 colonies/worlds survived that war (meaning ~145 Inner and ~590 Outer were lost, at least temporarily; during the war), some partially glassed, and mining corps went to the partially- and fully-glassed ones to dig up useful materials to help with reconstruction.  This post-war campaign/process continued for decades.  Survivors living in the wildernesses continued to be found, from time to time, throughout that entire span, some joining those digs/salvage operations, and some opting to be relocated to newly-colonized/terraformed worlds where it was easier to start over.

Inisfreeans never intervened… because the more humans spread, the weaker and more self-stalling/fighting they get; any species that fragments itself the way humans do, especially when they mislead and poison themselves, competing to no end, only holds itself back, causing all its people to be as weak as can be due to how many tasks and distractions they have, so many overlapping needs, thoughts, and mind-energy manifestations.  It is each species’ and person’s job/responsibility to figure this out and stabilize themselves.  If the Inisfreeans or others did it, that would only create further dependency/complexity, rather than the self-sufficient/sustaining/completing/balancing great individuals the Inisfreeans and other gods look for and know are best.  (Imagine what would happen if the whole Universe was full of people who looked to their gods for the solutions to all their problems, and if something required some of those stronger people (gods) to shift their focus, leaving all those people to their own devices; panic, then negativity-based manifestations, would ensue, getting out of hand quickly and for a long time –just as was the case on Earth in modern times.)

The Inisfreeans see the humans and Covenant species as the same; ugly morons keeping one another in check, which spares the Inisfreeans from having to have disgusting close contact.  No matter who keeps the humans and/or Covenant in check, even if it is themselves, that is considered perfectly fine; it is far better for primitive/bad species such as them to be ‘looped back on themselves’, as the Inisfreeans see/put it, than for the Inisfreeans to have to add such major tasking to their ‘plate’/schedule.  This is also the best way to teach/learn; ‘learning the hard way’ is arguably even more effective than learning in a fun, amusing, and engaging / full-bodied way, as pain, fear, and sadness are often better memory formers and memory ‘joggers’/recallers/refreshers than success and laughter.

This is also why Inisfreeans did not stop the Reapers in Mass Effect (late 2100s), or the Borg in Star Trek (mid 2100s to late 2300s).  If the Inisfreeans had stopped the Reapers or the Borg, the previously fighting/warring and infighting species across the Milky Way galaxy would not have been unified, not have been freed from billions of their weakest/worst members, and not have been forced to learn.  Species such as the Reapers and Borg, daunting and hideous though they can be, allow the Inisfreeans to stay focused on building up their private solar-system dimension, mapping all of Creation, deleting/recycling all pollution (including derelicts) they encounter, repairing and reactivating ruins of the good ancients, re-greening desertified/over-used worlds, establishing communication and relationships with the resurfacing ancients and hidden peoples, and so on; the Reapers and Borg are seen as outside/almost/pseudo-assets, operating autonomously and predictably, incapable of detecting –let alone interfering with or harming– the Inisfreeans and their allies, keeping the natural enemies of the Inisfreeans and their allies in check, too busy/occupied/defending to ever even notice any of the Inisfreean activities –even if their technology could.  Inisfreeans credit the Reapers and Borg with having prevented the breeding/spreading-crazed humans from occupying, polluting, and ruining hundreds or even thousands more worlds during the years leading up to the current UNSC’s might, and from preventing the UNSC from becoming not unlike the Covenant itself –and, of course, with keeping the Covenant from becoming even more spread-out and annoying/gross than it itself had become.  The Forerunners made Halos which used to take care of such things, and now, with the Halos not being fired anymore, it was the warring between the weakness-infected subspecies (e.g. modern humans being a subset/’race’ of their better/stronger/smarter ancient ancestors) which was doing the job –and better / more agreeably; without the need/firing of such things as the Halos.

Inisfreeans only monitor good forms/beings, preserving them.  The rest, they leave to their own devices.  Only when the occasional good/appropriate/correct/healthy/compatible form/body ‘pops up’, in spite of all the overlapping nonsense / poorly-/un-focused thought/manifestation-fields, do the Inisfreeans send some of their own to approach, either to liberate/extract such a person/’miracle’, or, at least, to make a perfected copy/version of them, leaving the original wherever she may wish to be.

Dr. Halsey may have been brainwashed to default to complex human tech’ (IOW:  the overly-complex way humans have developed their creations/technology/civilization/thinking), but she was also a well-formed, clever, brave woman who, like Auz, both resisted all of bad humanity… and used its best in order to learn from some of the ancients.  Like Auz, she found loopholes and did Black Operations.  Like Auz, she was a genius who saw and proved the value even of her/their form of kidnapping / human-trafficking.

This is why Dr. Halsey has been one of the very few humans of any of those/these colonies/worlds to have been offered political and secret asylum in Inisfree, and why the rest of the UNSC-protected worlds are –and likely always will be– regarded by the Inisfreeans to be nothing more than 1) places where they can farm/harvest decent-enough form-sakes from time to time, and 2) potentially needing Rapture Campaigns (global pollution-source cleanup/removal operations) of their own someday.  Rarely do any humans come close to being compatible with the Inisfreeans, and certainly not what the genius-Inisfreeans would call genius, too.  Even if all the UNSC colony-worlds got glassed or otherwise crippled/ruined yet again, it would not matter, as that would only mean another reduction in the numbers of monstrous beings such as the modern humans, and, of course, because the Inisfreeans have been proactively detecting and offering options to the few good manifestations (people) this whole time.  (The same is true even if the Halos were fired up again; they are based on an energy/technology that can only wipe out the weak, and which had failed at eradicating The Flood, the Forerunners, obsessed with their own form of technology just like the humans and Covenant now are, too busy/distracted/blinded by it to realize that they had manifested/triggered The Flood –or that they even had manifestation powers at all.)

Humans will keep spreading to and colonizing worlds in the Milky Way and beyond.  Their enemies will be allowed to attack them, keeping them focused on perpetuating their breeding and technology.  This keeps humans tricked and trapped on the outer surfaces of the worlds they are accustomed to being on, and that is their prison in Space, which the Inisfreeans see as “down in The Abyss / Hell”.

Once something else transitions in to take the UNSC’s place in the centuries and millennia ahead, those colonies will begin transforming into the worlds known in other disclosures/sagas, such as Dune, EVE Online, and Warhammer 40,000.  Note how in those stories/accounts/visions, humans are still limited to the outer surfaces of the worlds which still function like the Forerunner “shield worlds” (mini Dyson spheres protecting hollow planet interiors with spherical star-like portals of their own), and that humans are still limited to the same technological development type/trajectory they have been since modern Earth.  Some things, at least for some humans, never change –and maybe weren’t ever meant to.

For now (in the late 2500s), suffice it to say that the UNSC has successfully cleaned up and begun recolonizing hundreds of the worlds it once had, and eventually it will clean up and recolonize them all, adding even more.  There will even be some worlds where the UNSC and its former-Covenant alien allies colonize and coexist together.  Maybe there will even be a UNSC mission or two that requires glassing a world once/still occupied by lingering Covenant forces/loyalists, pushing the Covenant (or its replacement) back to inner-colonies of their own.

The Inisfreeans continue to clandestinely monitor those and all other worlds with decent/compatible-enough life on them, always sneaking in to copy and/or extract whomever there proves/becomes attractive enough to them.  Anytime pollution threatens part of the Inisfreeans’ eons-long project/campaign of regreening worlds and restoring their World Trees, they’ll send in some of their forces/units to cleverly right things, more and more these days without resorting to ‘direct action’ and exterminations; the Universe-spanning will/effect of their maker, High King Auz, will be helping them and everyone else to learn and work together better… until nothing needs to be terraformed, no one relies on technology to make things livable for them, and it has become unthinkable even for the distant descendants of the human colonists of these other worlds to ever do anything which would pollute or slow the return of the World Trees at all.  No matter how many billions of colonists there may be in a solar-system or on a world, his will always is there, eventually reigning supreme, even in their own hearts and minds.
