An independent subdivision of the Earth Federation's Tianem Fleet, to which the White Base is assigned prior to its return to space. The composition of the 13th Autonomous Corps changes over time, as the White Base sometimes travels by itself, and on other occasions is escorted by a handful of cruisers. [Gundam]

The Earth Federation Forces detachment stationed at the Frontier Side, which attempts to defend the Frontier colonies from the onslaught of the Crossbone Vanguard. [Gundam F91]

One of the Principality of Zeon's space fleets, based at the lunar city of Granada. While the Principality's other six fleets belong to the Space Attack Force, the 7th Division is part of Kycilia Zabi's Mobile Assault Force. This fleet is dispatched, somewhat too late, to help defend the space fortress Solomon. [Gundam]

A civilian manufacturing corporation based on the moon, which produces everything from home electronics to battleships. Although the company is headquartered at the lunar city of Anaheim, it also has offices and factories in major lunar cities such as Granada and Von Braun. After the end of the One Year War, Anaheim Electronics absorbs a number of wartime weapons developers, including the Zeonic corporation, and enters the mobile suit development business.

After the One Year War, Anaheim Electronics becomes the primary mobile suit supplier to the Earth Federation Forces. However, the company also funds and equips rebel movements like the Anti-Earth Union Group (AEUG) and Char Aznable's Neo Zeon, and in situations like the Gryps Conflict and Char's rebellion it often ends up providing weapons to both sides, always to Anaheim's own ultimate profit. [Gundam 0083, Zeta Gundam, Char's Counterattack]

An anti-Federation movement which opposes the oppressive tactics of the Federation's elite Titans taskforce. The AEUG's ultimate political agenda is to reform the corrupt Earth Federation government, but after the Colony 30 Incident of U.C. 0085, the organization becomes focused on the more urgent task of fighting the Titans with military force.

Many AEUG members are dissident Federation Forces officers, including its leader Commodore Blex Forer and his trusted advisor Lieutenant Quattro Bajeena. Its primary sponsor is the lunar manufacturing corporation Anaheim Electronics, and the group is supported by the space colonies of Side 2 and many of the lunar cities. The AEUG also maintains a secret base at the Sweetwater colony, where its flagship Argama was constructed. [Zeta Gundam]

After the One Year War the Augusta Base, where the Earth Federation Forces conducted their earliest Newtype research, becomes the first of the Federation's Newtype Labs. The Augusta Lab is located on the northern shore of the Clark Hill Reservoir in modern-day South Carolina, not far from Augusta, Georgia. During the Gryps Conflict, this facility produces the transformable mobile armor ORX-005 Gaplant and the cyber-Newtypes Rosamia Badam and Gates Capa. [Zeta Gundam]

A small fleet sent by the renegade Principality soldiers at the asteroid base Axis to support the Delaz Fleet. While the Axis Advance Fleet remains technically neutral throughout Operation Stardust, it provides weapons to its fellow rebels and stands by to retrieve Delaz Fleet survivors after the operation is over. This interplanetary convoy is made up of the battleship Gwanzan, eight Musai-class cruisers, and ten supply vessels, all under the command of Rear Admiral Yuri Hasler. [Gundam 0083]

An elite Crossbone Vanguard squadron commanded by Lieutenant Zabine Chareux. The squadron's mobile suits use a distinctive black-and-purple color scheme. [Gundam F91]

The Ronah family's business empire, established in U.C. 0055. Its subdivisions include the Buch Junk salvage company, the mobile suit manufacturer Buch Aerodynamics, and a vocational training school which later provides the basis for the private army known as the Crossbone Vanguard. [Gundam F91]

A group of renegade Principality of Zeon soldiers led by Commander Cima Garahau, which helps the Delaz Fleet carry out Operation Stardust. The Cima Fleet is composed of former members of the Principality's notorious marine corps, who are shunned by their former comrades. Cima's forces consist of the Zanzibar-class cruiser Lili Marleen, roughly six or seven Musai-class cruisers, and about 30 Gelgoog Marine mobile suits. [Gundam 0083]

A non-governmental organization established by the Earth Federation at the start of its space settlement program. The Colony Public Corporation is responsible for the management and administration of all the hundreds of space colonies in Earth orbit, and its employees ensure the proper operation of the colonies' life support systems, external mirrors, and air and water supplies. The organization itself remains stolidly neutral throughout the conflicts which rage in the Universal Century.

A new nation established by the Crossbone Vanguard, made up of the captured space colonies of the Frontier Side. Under the leadership of the Ronah family, Cosmo Babylonia is dedicated to the principles of aristocracy and noblesse oblige. Cosmo Babylonia soon establishes an alliance with the Jupiter Fleet, allowing it to stave off Earth Federation interference with the threat of an energy embargo. [Gundam F91]

A fighting force organized by the Ronah family in U.C. 0106, drawing on the skilled personnel of the Buch Concern and its vocational training school. This private army is meant to serve as an advance guard, or vanguard, for the nation of Cosmo Babylonia. Originally founded by Meitzer Ronah, the Crossbone Vanguard is eventually placed under the command of the mysterious Iron Mask.

After years of preparation, the Crossbone Vanguard enters combat with an assault on the space colony Frontier I in U.C. 0123. This highly motivated elite force far surpasses the Earth Federation Forces in terms of training and tactical skill, and its advanced mobile suits also outperform the Federation's antiquated machines. [Gundam F91]

A rebel organization composed of former Principality of Zeon soldiers, led by Vice Admiral Aiguille Delaz. After three years of planning and preparation, the Delaz Fleet emerges in U.C. 0083 to carry out Operation Stardust. Its forces consist of the Gwazine-class battleship Gwaden, roughly a dozen Musai-class cruisers, several dozen mobile suits, and assorted supply ships and cargo transporters. [Gundam 0083]

One of the three principal branches of the Principality of Zeon's military, nominally commanded by Captain Garma Zabi. The Earth Attack Force is created in February of U.C. 0079 in order to carry out a full-scale invasion of Earth. By September, when the Mobile Suit Gundam series begins, the Earth Attack Force controls two-thirds of the Earth's surface.

The Earth Attack Force is divided into five regional branches known as Terrestrial Mobile Divisions. The 1st Terrestrial Mobile Division is stationed in Europe and Central Asia, the 2nd and 3rd on the west and east coasts of North America, the 4th in Oceania and Australasia, and the 5th in Africa and the Middle East.

The unified world government that launched the space settlement program and now rules over both Earth and the space colonies. Its main decision-making body is the Earth Federation Assembly, which meets occasionally to pass new legislation.

Though not as cruel and aggressive as the Principality of Zeon's leaders, the bureaucrats who rule over the Earth Federation are corrupt, weak-willed, and insensitive to the space colonists' desire for independence. After the One Year War, the Federation decides to concentrate its energies on reconstructing Earth instead of the space colonies, further increasing political tensions.

The military arm of the Earth Federation. The Federation Forces are divided into several branches, including land, sea, air, and space forces. Until mass production of the RGM-79 GM begins in the final weeks of the One Year War, the Federation Forces are forced to battle the Principality of Zeon's mobile suits using conventional tanks, planes, and space fighters. Even in the postwar years, the Federation Forces are usually inferior to their opponents in terms of skill, morale, and equipment.

The space branch of the Federation Forces, established in U.C. 0059 in response to Side 3's declaration of independence. The Federation Space Force is headquartered at Luna II, and after the One Year War it also maintains outposts at many space colonies and at asteroid bases such as Konpeitoh. The EFSF fleet is primarily made up of Salamis-class space cruisers, upgraded versions of which remain in service even after the introduction of newer models.

A civilian research institute, sponsored by the Principality of Zeon, which is established in June of U.C. 0079 to investigate Newtype phenomena. In addition to scientific research, the Flanagan Institute's work involves developing weapons for use by Newtypes, recruiting Newtype test subjects, and training them to use their powers in battle. [Gundam, 08th MS Team]

Thanks to the development of the thermonuclear reactor, the people of the Universal Century have access to safe and abundant fusion power. However, these reactors are fueled by a rare helium-3 isotope which is almost nonexistent on Earth. This precious fusion fuel is collected from the atmosphere of the planet Jupiter and brought back to the Earth sphere by a non-governmental organization known as the Jupiter Fleet, which operates a fleet of Inter-Planetary Helium Carriers.

The helium-3 supplied by the Jupiter Fleet is a vital resource in the age of space settlement, and during wartime its vessels are protected from attack by international treaties. The Jupiter Fleet, in turn, is technically neutral, but its fuel monopoly allows it to exert considerable political influence. [Gundam, Zeta Gundam, Gundam F91]

A terrestrial resistance group which cooperates with the AEUG to fight the tyranny of the Titans. While the AEUG retains the rank structure and military discipline of the regular Federation Forces, Karaba is an informal guerilla organization made up of civilian volunteers, including a number of former White Base crewmembers. With few safe bases to call its own, Karaba eventually turns the captured transport plane Audhumla into its airborne command post. [Zeta Gundam]

A mechanized battalion supervised by Lieutenant Colonel Kojima, which fights as part of the Federation's Southeast Asia forces during the latter half of the One Year War. The Kojima Battalion is organized into two mobile suit companies, each subdivided into four teams of three mobile suits apiece, as well as an anti-mobile suit infantry company. 2nd Lieutenant Shiro Amada commands the Kojima Battalion's 08th MS Team. [08th MS Team]

The Earth Federation Space Force is reorganized after the Gryps Conflict, and its fleets are distributed among the Sides in order to suppress resistance in the space colonies. However, these colony garrisons are seldom able to leave their posts, so in U.C. 0090 a special auxiliary unit called the Londo Bell is organized to patrol the rest of the Earth sphere and investigate signs of anti-Federation resistance. The Londo Bell's task is essentially the same as that of the Titans, but since the Londo Bell's ranks are comprised of former AEUG members who put their lives on the line to oppose the Titans, they carry out their mission in a far more humane fashion.

Despite the importance of its mission, the Londo Bell is always short of personnel and resources. It isn't until Char Aznable and his Neo Zeon fleet take over the refugee colony Sweetwater at the end of U.C. 0092 that the Londo Bell is reinforced in earnest, with the addition of Captain Bright Noa and the newly-constructed battleship Ra Cailum. By the time Char's Neo Zeon forces seize control of the asteroid 5th Luna, the Londo Bell fleet consists of the Ra Cailum, the cruisers Ra Zyme, Ra Kiem, and Ra Chutter, and roughly 20 mobile suits. [Char's Counterattack]

A manufacturing corporation based in New Hong Kong, which lends supplies and support to Karaba and its AEUG allies. Though Luio Woomin is the rebels' actual sponsor, his daughter Stephanie serves as his representative in dealing directly with the resistance fighters. [Zeta Gundam]

A civilian company that develops many of the weapons used by the Principality of Zeon. When the Principality first considers new weapons designed for the Minovsky particle era, MIP's concept of a highly mobile space fighter is rejected in favor of Zeonic's mobile suits. However, MIP's concept later reappears in the form of mobile armors like the MA-05 Bigro. Although the company is best known for its mobile armors, it's also the developer of the highly successful amphibious mobile suit MSM-07 Z'gok.

One of the three principal branches of the Principality of Zeon's military, commanded by Rear Admiral Kycilia Zabi. The Mobile Assault Force is based at the lunar city of Granada. In addition to the space fleet known as the 7th Division, Kycilia's forces include assorted intelligence services, research projects, resource-mining operations, and special forces teams.

Located in Japan, this is one of a handful of Newtype research institutes established by the Earth Federation Forces after the One Year War. The Murasame Lab goes on to produce the fearsome transformable mobile armors MRX-009 Psyco Gundam and MRX-010 Psyco Gundam Mk.II, but fields only a single cyber-Newtype pilot, who is given the codename Four Murasame. [Zeta Gundam]

A name used by two separate movements which follow in the footsteps of the Principality of Zeon. In U.C. 0088, the renegade Principality forces based at the asteroid Axis adopt the name Neo Zeon and set out to restore the dominion of the Zabi family. Nominally led by the Zabi heir, the child princess Mineva Lao Zabi, this Neo Zeon movement is in fact controlled by Mineva's regent Haman Karn.

In U.C. 0092 the legendary Char Aznable returns as the leader of a second Neo Zeon movement, which aims to continue the work of Char's father Zeon Zum Deikun. Char's Neo Zeon fleet is based at the refugee colony Sweetwater and consists of the battleship Rewloola, thirteen Musaka-class cruisers, and roughly a hundred mobile suits. [Char's Counterattack]

During the One Year War, the Principality of Zeon's Flanagan Institute conducts pioneering research into Newtype phenomena and their military applications. In U.C. 0082, the Earth Federation Forces establish their own network of Newtype research institutes to continue in the Flanagan Institute's footsteps. These Newtype Labs devise methods for turning ordinary humans into artificial cyber-Newtypes, and create powerful mobile armors for their use.

There are roughly half a dozen of these institutes on Earth, including the Murasame Lab in Japan, the Augusta and Oakland labs in North America, the Kilimanjaro Lab in Africa, and the Pyongyang Lab in Korea. The Titans maintain their own Newtype lab at the Gryps space colony and, as their influence grows, the other Newtype Labs align themselves with the Titans as well. [Zeta Gundam]

Located in North America, this is one of a handful of Newtype research institutes established by the Earth Federation Forces after the One Year War. Around the time of the AEUG's assault on Jaburo, the Oakland Lab is taken over by the Titans, who dispatch test pilot Buran Blutarch and the transformable mobile armor NRX-044 Asshimar to intercept the escaping AEUG forces. [Zeta Gundam]

In U.C. 0068, Degwin Sodo Zabi becomes leader of the Republic of Zeon, the autonomous government of Side 3. The following year he establishes a new government, declaring himself sovereign of the Principality of Zeon. This is the rebel space nation that challenges the Earth Federation during the One Year War.

Although the Principality is effectively a totalitarian dictatorship ruled by the Zabi family, it retains some vestiges of the former democratic government, including a powerless national assembly and a figurehead prime minister.

The original democratic government of Side 3. The Republic is established in U.C. 0058 under the leadership of Zeon Zum Deikun, as an independent nation beyond the control of the Earth Federation. Eleven years later, it becomes the Principality of Zeon, a dictatorship ruled by the Zabi family. The Republic is restored at the end of the One Year War, but in its new incarnation it's seen by many as an illegitimate puppet government under Federation control.

The founders of the Crossbone Vanguard and Cosmo Babylonia, whose original family name was Buch. Having made a fortune in the salvage business, family patriarch Scharnhorst Buch purchased the Ronah name in U.C. 0068 to suit his aristocratic ambitions. For a family that believed itself truly superior to the common masses who polluted the Earth sphere, this act seemed like a suitable way to distinguish itself.

In addition to the business empire known as the Buch Concern, the Ronah family has also held important positions in the Earth Federation Assembly and the Colony Public Corporation, allowing it to advance its own grand plans. In U.C. 0123, the Ronah family uses its private army, the Crossbone Vanguard, to seize the Frontier Side and found the nation of Cosmo Babylonia. [Gundam F91]

One of the three principal branches of the Principality of Zeon's military, commanded by Vice Admiral Dozle Zabi. The Space Attack Force is made up of six battle fleets, which provide the bulk of the Principality's space power. Dozle's headquarters are at the asteroid fortress Solomon, which serves as a frontline base for the Space Attack Force.

A military research organization established by the Earth Federation Forces in U.C. 0093, which incorporates a number of formerly separate research institutes and intelligence agencies. SNRI specializes in strategy, tactics, and weapons development, and goes on to propose the creation of a new line of highly compact mobile suits.

In U.C. 0111, the Federation Forces decide to adopt SNRI's Formula series for their next generation of mobile suits, and SNRI replaces Anaheim Electronics as the Federation's premier weapons developer. However, due to Anaheim's manufacturing expertise, the company's services are retained to put SNRI's designs into mass production. [Gundam F91]

An elite branch of the Federation Forces created in the aftermath of Operation Stardust. The Titans are charged with hunting down the renegade soldiers of the Principality of Zeon, and suppressing anti-Federation movements, but their overzealous actions soon create a new generation of resistance groups. The Titans are initially headquartered at the Gryps space colony, but as they gain control over the regular Federation Forces and form an alliance with the Republic of Zeon, they also take over Luna II and the Gate of Zedan. [Gundam 0083, Zeta Gundam]

The civilian company that develops the first mobile suits, and goes on to become the Principality of Zeon's main mobile suit supplier. Zeonic is responsible for the development of the MS-05 Zaku I and MS-06 Zaku II, as well as later models like the MSM-04 Acguy and MS-14 Gelgoog.

After the One Year War, the company merges with Anaheim Electronics, and its facilities at the lunar city of Granada become one of Anaheim's main mobile suit factories. Many of Zeonic's engineers likewise continue their work as Anaheim employees, though some reportedly flee to the asteroid base Axis along with the defeated forces of the Principality.

A civilian company that develops many of the weapons used by the Principality of Zeon, including the mobile suits MS-09 Dom and MSM-03 Gogg. Zimmad triumphs over its longtime rival Zeonic when the MS-R09 Rick Dom is chosen to succeed the Zaku II as the Principality's main space combat mobile suit. However, its next design, the YMS-15 Gyan, is rejected in favor of Zeonic's MS-14 Gelgoog. After the end of the One Year War, Zimmad devotes itself to maintaining the equipment of the Republic of Zeon's military forces.
