A system which allows mobile suits to maneuver more efficiently in zero gravity. Conventional spacecraft employ vernier thrusters to change their direction, but using verniers to turn and perform evasive maneuvers in combat consumes a lot of propellant. When the first mobile suits were developed, the engineers of the Zeonic company devised an alternative maneuvering method based on active mass movement.

When one part of a mobile suit is moved, it produces a counter-movement in the opposite direction, as per Newton's Third Law of Motion. For example, when a mobile suit swings its arm to the right, its body turns to the left in response. The AMBAC system uses this effect to adjust the mobile suit's direction without expending propellant. Thus, in zero gravity the mobile suit's arms and legs are not dead weight, but a vital component of its maneuvering system. After the One Year War, some mobile suits are also equipped with movable binders which function as part of the AMBAC system.

While armor materials like Luna Titanium and Gundarium alloy are highly effective against projectiles, they offer virtually no defense against beam weapons. However, some protection can be provided by anti-beam coating, an ablative material which partially absorbs the kinetic energy of mega particle beams. This coating evaporates due to the extreme heat, so it can only be used a few times before losing its effectiveness. During the One Year War, this coating is used on the shields of the MS-14 Gelgoog and RX-78NT-1 Gundam, and after the war it becomes a standard feature on mobile suit shields.

A nickname for vernier thrusters, derived from the "apogee kick motors" used to position artificial satellites into geosynchronous orbit around the Earth. These devices are activated at the satellite's apogee, the highest point in its elliptical orbit, and the term "motor" indicates that they are solid-fuel rockets. While early mobile suits use solid-fuel motors for maneuvering, later models often use liquid-fuel rockets for better performance.

A new type of control lever used in the mobile suits of the U.C. 0090 era. When the pilot grasps the spherical controller, he can use his fingers to operate the individual control switches, while moving the sphere itself to maneuver the mobile suit. [Char's Counterattack]

Armor plating is used to protect the vital areas of a mobile suit or mobile weapon, such as its cockpit, engines, and joints. Early mobile suits like the MS-05 Zaku I and MS-06 Zaku II are armored with super-hard steel alloy, but later models use hybrid armor made up of layers of titanium alloy and ceramic material, which offers better impact resistance and lighter weight.

The Luna Titanium alloy used in the RX-78 Gundam, which is later dubbed Gundarium, is a super-hard alloy made up of rare metals. While far stronger than conventional armor materials, it's difficult and expensive to produce, and thus is seldom used in mass-produced mobile suits.

Even in the Universal Century, it remains impossible to artificially nullify or generate gravity. However, in the weightless environment of space, the centrifugal force produced within a rotating cylinder can be used to simulate Earth's gravity. This is the principle used in the space colonies, and smaller centrifugal devices are sometimes installed in spacecraft like the assault carrier White Base.

Likewise, the lift-generating Minovsky craft system, which vehicles like the White Base use to float in Earth's atmosphere, isn't a true anti-gravity system. Instead, it uses a cubic lattice of Minovsky particles to push the vessel away from the Earth's surface.

A crude but effective weapon used to defend the Principality of Zeon's asteroid fortresses. These missiles are just small asteroids, roughly twenty to thirty meters in diameter, fitted with rocket engines so that they can be launched at enemy warships. Although these asteroid missiles are equipped with communication antennas for remote control, the combination of Minovsky particle interference and the asteroids' poor maneuverability renders them highly inaccurate. As a result, they're effective only against large fleet formations, but a direct hit from one of these projectiles is enough to destroy an enemy warship. [Gundam]

An optional device used by the RGZ-91 Re-GZ. The Back Weapon System is the latest in a series of support devices, like the G-Armor and the G-Defenser, which dock with mobile suits to increase their operating range, mobility and firepower. When docked with the Re-GZ, the Back Weapon System also functions as a wave rider, enabling the mobile suit to undergo atmospheric entry. [Char's Counterattack]

An atmospheric entry device used during the Gryps Conflict. As the mobile suit enters the atmosphere, a bowl-shaped ballute (balloon parachute) deploys to protect it from the friction heat of atmospheric entry. The balloon then detaches, leaving the mobile suit with chest and leg hover units which ease its descent to the ground. If the mobile suit reaches the ground without expending all the fuel in the leg units, these devices can also be used for hovering and high-speed strike missions. [Zeta Gundam]

This term is used for a variety of defensive systems based on the principles of Minovsky physics. The most common type is the I-field generator employed by the MA-08 Big Zam, RX-78GP03 Dendrobium and AMA-X2 Neue Ziel, whose invisible force field deflects enemy beam attacks but has no effect against missile and projectile weapons. The RX-93 Nu Gundam can use its fin funnels to generate a protective barrier which not only deflects incoming beams, but also repels enemy funnel weapons.

A heavy weapon - technically, a giant rocket launcher - which is often used by mobile suits to attack ships and fortifications. Its variants include the 240mm Zaku Bazooka, the 360mm Giant Bazooka used by the MS-09 Dom, and the Gundam's Hyper Bazooka.

All Crossbone Vanguard command mobile suits are equipped with this device, which projects an image of the appropriate squadron emblem from the machine's back. This beam flag helps guide the commander's squadron into formation, but also gives the enemy an obvious target - a tradeoff that the Crossbone Vanguard are willing to make, in accordance with their aristocratic ideals. [Gundam F91]

A heavy weapon used by mobile suits of the U.C. 0120 era in place of projectile-firing bazookas. Thanks to their high-performance generators, these mobile suits can support multiple beam weapons in addition to the standard beam rifle. The beam launcher fires a low-velocity beam with high destructive power. [Gundam F91]

A compact mega particle cannon, comparable to the main guns of a space warship, which can be carried by a mobile suit. The rifle's energy is supplied by an energy capacitor (E-CAP), rather than the mobile suit's own reactor, and this energy supply can only be replenished inside a base or carrier vessel. First developed by the Earth Federation Forces, this weapon is used by the RX-78 Gundam and RX-77 Guncannon, and later by the Principality of Zeon's MS-14 Gelgoog. By the time of the Gryps Conflict, the beam rifle has become standard equipment for all mobile suits.

A mobile suit melee weapon first employed by the RX-78 Gundam. The hilt of the beam saber houses an energy capacitor (E-CAP) like that of a beam rifle, whose stored Minovsky particles are released to form a lethal energy blade. The mass-produced RGM-79 GM and MS-14 Gelgoog are also equipped with this weapon, and it becomes a standard feature after the end of the One Year War.

A new protective device used by the mobile suits of the U.C. 0120 era. Thanks to their increased generator output, the scaled-down mobile suits of this era are able to use beam technology for defensive purposes. Unlike an I-field generator, which is effective only against beam attacks, the beam shield blocks both beam and projectile weapons.

The beam shield generates a plane of energy similar to the blade of a beam saber. This plane is divided into multiple sections, which can be turned on or off as needed to conserve energy. Individual sections are also automatically deactivated whenever they're in danger of coming into contact with the mobile suit itself. [Gundam F91]

A general term for all energy weapons based on Minovsky physics, such as beam sabers and beam rifles. Most beam weapons fire blasts of mega particles, so they can be considered variants of the mega particle cannon. One exception is the beam saber, which instead emits high-energy Minovsky particles.

A tactic used to block enemy beam weapons during large-scale space battles. Mega particle beams gradually scatter and weaken even in a vacuum, but their effective range is even shorter in Earth's atmosphere, due to collisions with atmospheric particles. By emitting a cloud of gas which is specially formulated to absorb mega particle beams, it's possible to create this effect in space as well. The resulting beam-diffusing "curtain" reduces the destructive power of enemy beam blasts as they pass through it, but since it has the same effect on the weapons of both sides, this tactic isn't always appropriate for the situation at hand. During the battles of Solomon and A Baoa Qu, the Earth Federation Forces use Public assault ships to deploy this beam-diffusing gas, which is launched inside specialized missiles. [Gundam]

The mobile suits of the One Year War era use an orthodox humanoid design, with movable arms and legs which can be employed for zero-gravity maneuvering thanks to the AMBAC system. Postwar designs develop this concept further, equipping the mobile suit with independently movable parts called binders in addition to the standard four limbs. These devices can likewise be used for AMBAC maneuvering, and their movability makes it easy to change the direction of any weapons or thrusters housed within the binder itself. The simple construction of these binders also provides ample space for propellant storage.

This concept is employed in the prototype mobile suits produced by the Gundam Development Project - for example, in the flexible thruster binders of the RX-78GP02A and the tail binders of the RX-78GP03S. Later variants include shoulder binders, wing binder, and vernier binders. [Gundam 0083, Zeta Gundam]

A new kind of man-machine interface which allows machines to be controlled by human thoughts. While functionally similar to the psycommu system, the bio-computer places less strain on its human operator. The bio-computer is originally intended to help the disabled, but its development is ultimately funded by the Earth Federation Forces, who hope to employ it as a mobile suit control system and install it in the F91 Gundam for experimental purposes.

As its name implies, the bio-computer is similar in structure to a human brain, and its operating processes resemble human thoughts and feelings. Rather than merely displaying data on a computer monitor, the bio-computer can relay it directly to the pilot in the form of sensory information, so what the machine "feels" can also be experienced by the human operator. However, the full latent potential of this system can only be tapped by a Newtype pilot. [Gundam F91]

A variant of the psycommu system, developed by Anaheim Electronics and experimentally installed in the MSZ-006 Zeta Gundam. Its full capabilities are unknown, but the bio-sensor does allow a Newtype pilot to control a mobile suit via mental commands. Paptimus Scirocco's custom-made mobile suit PMX-003 The O is also equipped with this device. [Zeta Gundam, Gundam F91]

A remote-controlled weapon used by the mobile armor MAN-08 Elmeth. The Elmeth's bits are independent fighting machines, each one measuring 8.4 meters long and equipped with a thermonuclear reactor, rocket thrusters, maneuvering verniers, optical sensors, and a beam cannon. The Elmeth's psycommu system allows a Newtype pilot to control the bits via mental commands - which, unlike conventional forms of remote control, are unaffected by Minovsky particle interference.

After the end of the One Year War, research continues into psycommu technology and remote weaponry. The funnel, a compact version of the Elmeth's bits, is developed by renegade Principality of Zeon soldiers at the asteroid base Axis. Meanwhile, the Earth Federation Forces duplicate the Principality's psycommu technology using information obtained from captured enemy facilities. The Federation's research eventually leads to the reflector bits used by the MRX-010 Psyco Gundam Mk.II, and the fin funnels carried by the RX-93 Nu Gundam. [Gundam]

A projectile-firing bazooka used by the RMS-099 Rick Dias and MSN-00100 Hyaku Shiki. As its name indicates, the clay bazooka was originally designed to fire adhesive rounds which immobilize enemy machines rather than destroying them outright. However, this weapon can fire several different types of ammunition, and it's normally used with conventional explosive shells. [Zeta Gundam]

The space colony known as Gryps, the original headquarters of the Earth Federation's elite Titans taskforce, is made up of two separate segments designated Gryps 1 and Gryps 2. In order to punish rebellious space colonies, the Titans eventually remodel Gryps 2 into a giant laser cannon. This colony laser works on the same basic principle as the Solar Ray System used at the end of the One Year War, but since Gryps 2 is equipped with a thermonuclear pulse thruster, it can be moved around the Earth sphere to strike at whatever target the Titans choose. Its power is supplied by a huge array of solar panels, which trail along behind the colony laser wherever it goes. [Zeta Gundam]

A standard feature of the new space warships introduced after U.C. 0090. During battle, the ship's command crew can transfer from the vulnerable main bridge to this heavily-armored control room deeper inside the ship. [Char's Counterattack, Gundam F91]

A mind control system installed in the MRX-009 Psyco Gundam, which compels its cyber-Newtype pilot to fight in battle. The NRX-055 Baund Doc appears to be equipped with a similar device. [Zeta Gundam]

In the world of the Universal Century, communication between ships, mobile suits, and the like is greatly complicated by the widespread use of Minovsky particles. When these particles are scattered in high densities, they render radio communication impossible. Under these conditions, the best alternative is to transmit data in the form of low-intensity laser pulses. Although these laser signals are limited to relatively short ranges, this is the standard means of communication in the battlefield, and these messages are very difficult for enemies to intercept. When in direct physical contact, it's also possible to communicate via a contact link.

An alternative means of short-range voice communication. When mobile suits come into direct physical contact with each other, or with other vehicles, sound can be transmitted between them via vibrations in their outer armor. A mobile suit can reach out with its manipulator to establish the link, and these sound vibrations can also be relayed through wires, including the wire-guns used by human workers. Unlike radio communications, conversations transmitted in this way are almost impossible to intercept.

The prototype mobile suits produced by the Earth Federation Forces' Operation V, such as the RX-78 Gundam, are equipped with a central block which houses the mobile suit's cockpit, control systems and main power source. This core block can eject in case of emergency and unfold into a small Core Fighter. Due to its high cost, this system is omitted from mass production machines. [Gundam, Gundam 0083]

A deception device that takes advantage of Minovsky particle interference. Thanks to this interference, warfare in the Universal Century era relies heavily on visual sensors, which can be tricked by inflatable decoys. These decoy balloons are designed to mimic mobile suits, asteroids, and even warships. More sophisticated varieties are equipped with small maneuvering verniers, allowing them to move in a realistic manner and register on infra-red sensors. [Zeta Gundam, Char's Counterattack]

Most of the early mobile suits used during the One Year War lack emergency escape mechanisms. The core block system used in the Earth Federation's RX series, meanwhile, is too expensive for mass production. After the war, when the linear floating seat and 360-degree panoramic screen become standard equipment, this problem is addressed by turning the entire cockpit assembly into a spherical escape pod which can be ejected in emergencies.

This ejection pod design proves effective and inexpensive, and soon becomes a standard feature. However, since these devices are unable to survive the explosion of a mobile suit's main reactor, research continues into the core block system and other escape mechanisms. [Zeta Gundam]

In the closed environment of a space colony or lunar city, atmospheric pollution must be kept to an absolute minimum, so electric cars are used for personal transportation. Even military vehicles, like the missile trucks used by colony defense forces, run on electrical batteries. Strict speed limits are also enforced inside space colonies, so for longer trips, it's more convenient to travel via the colony's linear car system.

A mega particle cannon like those installed in space warships requires a large electrical power source, a steady supply of energy in the form of Minovsky particles, and a massive energy condensor to compress the latter into mega particles prior to firing. Therefore, it initially seems impossible to install these weapons in mobile suits. These issues are addressed with the development of the energy capacitor, which makes it possible to create compact beam weapons with greatly reduced power and energy requirements.

The E-CAP stores Minovsky particles in a compressed, high-energy state, just short of fusing into mega particles. The power output of a mobile suit's generator, although far lower than that of a warship, is sufficient to complete this process and form mega particles. However, the mobile suit is unable to replenish the supply of Minovsky particles inside the E-CAP, and once this energy supply is exhausted the weapon must be returned to a base or carrier vessel for recharging.

A removable external energy capacitor (E-CAP), which can be replaced in combat just like a rifle magazine. By the time of the Gryps Conflict, most beam rifles use these interchangeable energy packs, giving them a far greater energy supply than the weapons used during the One Year War. [Gundam 0083, Zeta Gundam, Gundam F91]

A psycommu-controlled remote weapon developed exclusively for the RX-93 Nu Gundam. Each of these devices is made up of a central thruster unit and two generator arms, and these three movable sections can be used for AMBAC maneuvering, conserving the fin funnel's propellant supply and extending its operating time. Each fin funnel houses a built-in mega particle cannon, whose beam is accelerated as it passes between the generator arms, and a defensive beam barrier can be generated between the funnels. This barrier not only deflects incoming beam attacks, but also keeps out enemy funnels. [Char's Counterattack]

Installed on the XM-07 Vigna Ghina, these devices are improved versions of the shelf nozzle used by other Crossbone Vanguard command mobile suits. The fin nozzles, which project laterally from the Vigna Ghina's backpack, are connected directly to the mobile suit's generator for better energy transmission efficiency. [Gundam F91]

An optional accessory for the RX-178 Gundam Mk.II, which is subsequently developed into the binder on the back of the MSZ-006 Zeta Gundam. The flying armor functions as a wave rider, allowing the Gundam Mk.II to enter Earth's atmosphere from orbit, and also serves as a hovercraft once it reaches the ground. [Zeta Gundam]

This psycommu-controlled remote weapon is a successor to the bits used by the mobile armor MAN-08 Elmeth. The first machine equipped with funnels is the AMX-004 Qubeley, developed by renegade Principality of Zeon soldiers at the asteroid base Axis. Unlike the Elmeth's massive bits, which were powered by built-in thermonuclear reactors, the Qubeley's funnels are tiny devices whose beam guns run on compact E-CAPs. The name "funnel" is derived from the conical shape of these weapons.

Thanks to their smaller size, funnels are hard to spot or shoot down, but their limited operating time means that they must continually return to the mobile suit to replenish their propellant supply and recharge their E-CAPs. As research continues, new types of funnel appear, like the oversized devices used by the NZ-333 Alpha Azieru and the unique fin funnels of the RX-93 Nu Gundam. [Zeta Gundam, Char's Counterattack]

A device which converts the energy of a mobile suit's thermonuclear reactor into electrical power. Electricity can be obtained directly from the reactor core via magnetohydrodynamics (MHD), and the heat emitted by the reactor can also be converted to electrical power using turbines. In this fashion, the reactor provides the mobile suit with an abundant supply of electricity.

An explosive device designed to be thrown by a mobile suit's manipulator, just like the hand grenades used by infantry soldiers. One noteworthy variant is the cracker, a multiple-warhead type used by the Principality of Zeon's ground forces, which breaks up into several smaller explosives in midair.

These weapons are often attached to mobile suit rifles, like the grenade launchers used by infantry soldiers, although in some cases they're integrated into the mobile suit's shield, forearms, or hips instead. The grenade launchers used during the One Year War fire unguided grenades, but some later versions launch self-propelled homing missiles with their own optical guidance systems.

A super high-tensile alloy originally known as Luna Titanium. Originally intended for use inside thermonuclear reactors, this alloy's superb strength, durability, heat resistance and radiation-absorbing properties make it an ideal material for mobile suit armor. The alloy is first used in the RX-78 Gundam, and later renamed Gundarium Alpha in honor of this famous mobile suit.

After the One Year War, the material is further refined by renegade Principality of Zeon soldiers at the asteroid base Axis. The Axis researchers develop an improved lightweight version called Gundarium Gamma, which is introduced in the RMS-099 Rick Dias and widely used throughout the Gryps Conflict. However, the difficulty of processing the titanium, and the expense of the rare metals used, render Gundarium alloy unsuitable for mass-produced mobile suits.

An attachment point for weapons, shields, spare ammunition, or optional mission-specific equipment. Hardpoints can also be used to store carried weapons when a mobile suit needs its manipulators free for other purposes, or when a transformable mobile suit changes into its mobile armor form.

An axe-like weapon used by the MS-06 Zaku II, whose name is short for "tomahawk". Thermal energy is relayed through the mobile suit's hand to heat the heat hawk's blade, allowing it to slice through the armor of enemy warships or mobile suits.

A close-range weapon installed in the right arm of the MS-07B Gouf. This retractable cable delivers a high-voltage electrical shock when it comes into contact with an enemy mobile suit, damaging its internal systems and stunning its pilot. [Gundam, 08th MS Team]

A melee weapon similar to the heat hawk, whose swordlike blade is heated by thermal energy relayed through the mobile suit's hand. The MS-07B Gouf. and MS-09 Dom are each equipped with their own characteristic heat sabers.

A system installed in the RX-78 Gundam, which pumps out air to counter the friction heat of atmospheric entry. The mobile suit's internal cooling systems must also be engaged to deal with the heat that penetrates the air field. [Gundam]

A reusable vehicle designed to transport cargo between Earth and space. The HLV's streamlined shape allows it to survive atmospheric re-entry and, after being fitted with rocket boosters, it can then be launched back into orbit. During the One Year War, these vessels were used by the Principality of Zeon to land forces on Earth, to launch extracted mineral resources into space, and then finally to evacuate fleeing troops. [Gundam 0083, Zeta Gundam]

A rare isotope of helium, which has only one neutron instead of the usual two. Helium-3 can be combined with deuterium, an isotope of hydrogen, in a "clean" fusion reaction which emits no harmful neutrons and thus requires far less radiation shielding than other types of fusion. In the Universal Century, this deuterium-helium-3 reaction is used in the thermonuclear reactors that power every mobile suit and space warship.

However, since only 0.015% of all helium atoms are of this type, helium-3 is virtually nonexistent on Earth. The only way to obtain this vital fusion fuel is to collect it from the atmosphere of the solar system's outer planets, a task performed by the vessels of the Jupiter Fleet.

A small manipulator which is normally retracted, folded, or otherwise concealed, like those installed in the mobile suit PMX-003 The O. Not only can these hidden hands carry extra weapons, but the element of sheer surprise provides a tactical advantage, since mobile suits rely heavily on computer backup and can't deal as effectively with an enemy if they don't have complete data on its combat capabilities. [Zeta Gundam]

A lightweight one-man glider equipped with a compact jet engine. These devices are used for sporting events inside space colonies, and they also come in handy as escape devices for aircraft passengers. [Zeta Gundam]

A unique type of sensor used in the heads of Crossbone Vanguard mobile suits, which consists of a pair of compound sensors installed behind two goggle-like lenses. This arrangement is highly effective for judging distances and three-dimensional positions in space, and its performance is many times better than that of the mono-eye used in the Principality of Zeon's mobile suits. [Gundam F91]

When Minovsky particles are released into the air or into open space, the positive and negative particles spontaneously align themselves into a three-dimensional cubic lattice. Due to the repulsive and electrostatic forces between the Minovsky particles, this lattice functions as a kind of a force field, which is referred to as an I-field. This field has difficulty permeating conductive materials like metal, water, and plasma, and it exerts a repulsive force against mega particles.

This phenomenon has numerous applications. I-fields are used to confine plasma inside thermonuclear reactors, to create lift via the Minovsky craft system, and to focus and accelerate mega particle beams. The protective device known as the I-field generator, meanwhile, uses a powerful I-field as a barrier to deflect enemy beam attacks.

A protective device which uses a powerful I-field to deflect enemy mega particle beams. Due to its high power requirements, the I-field generator can only be installed in large mobile weapons like the MA-08 Big Zam, RX-78GP03 Dendrobium and AMA-X2 Neue Ziel. When the generator is activated, the I-field forms an invisible barrier around the mobile weapon, protecting it from incoming beam attacks. However, this barrier has no effect against solid objects like missiles and projectiles, and beam weapons can still be used at point blank range within the barrier's boundary. [Gundam, Gundam 0083]

A remote weapon designed for use with the quasi-psycommu system system. These disc-shaped devices are armed with internal beam guns and controlled via wire cables. Every time an incom changes its flight direction, it deploys a tiny relay incom to hold the wire in place and maintain its connection to its parent mobile suit. When the pilot recalls the incom, it retraces its course as the wire is retracted.

A class of huge transport ships used by the Jupiter Fleet to collect helium-3 from the atmosphere of the outer plants and carry it back to the Earth sphere. The transport ship Jupitris, a typical IPHC vessel, is 2000 meters long and propelled by a set of thermonuclear pulse engines. [Zeta Gundam, Gundam F91]

An optional back-mounted booster device used by the MSM-03C Hy-Gogg and MSM-07E Z'gok E. This so-called jet pack actually contains a pair of chemical rockets, which the mobile suit uses to launch out of the water and glide to a landing. The expended jet pack is then detached and discarded. [Gundam 0080]

Even before the introduction of the mobile suit, powered suits and worker pods were used for mundane tasks like space colony construction. In later years, as military mobile suit technology makes its way into the civilian sector, scaled-down mobile suits are developed to fill this role. The smallest of these worker machines are known as junior mobile suits. These machines stand about two meters tall and lack an enclosed cockpit, requiring the operator to wear a normal suit when using the machine in space or on the lunar surface. [Zeta Gundam]

This system uses an external power source - namely, a powerful laser - to heat a spacecraft's propellant. More efficient than the thermonuclear rocket engines used by space warships, this mechanism enables spacecraft to minimize their propellant consumption as they launch out of lunar orbit. Major lunar cities like Von Braun are equipped with laser ignition stations for boosting transport ships into space. The assault carrier Albion is one of the few military vessels designed to use this system. [Gundam 0083]

These are commuter trains which travel on rails along the outside of a space colony, running from station to station just like the underground rail systems of terrestrial cities. Due to the strict driving speed limits enforced within space colonies, long trips are typically made using these linear cars.

A new type of pilot seat which becomes standard after the One Year War. In this arrangement, the seat is suspended in the center of the cockpit, supported by a linear arm which electromagnetically counters G-forces and impact shocks in order to protect the pilot. When used in conjunction with the 360-degree panoramic screen, the linear floating seat also gives the pilot a larger field of view and eliminates blind spots. Due to the superior performance of this setup, even older mobile suit models are often refitted with linear floating seats and panoramic screens.

A super high-tensile alloy developed by Earth Federation Forces researchers at the asteroid base Luna II. Luna Titanium is used in the armor of the RX-78 Gundam, RX-77 Guncannon and RX-75 Guntank, as well as early pre-production mobile suits like the RX-79[G] Gundam and RGM-79[G] GM. However, the difficulty and expense of producing this alloy preclude its use in mass-produced mobile suits like the RGM-79 GM. After the One Year War, the material is renamed Gundarium in honor of the famous mobile suit.

The standard weapon of the MS-06 Zaku II is a 120mm machine gun, a rapid-fire weapon as powerful as a tank cannon. Machine guns of various kinds, with calibers ranging from 75 to 120mm, are a universally popular mobile suit weapon. However, they're of limited effectiveness against the RX-78 Gundam, and other mobile suits with Luna Titanium or Gundarium armor.

A special membrane treatment applied to mobile suit joints to improve their response speed. The mobile suits developed by the Earth Federation Forces use special actuators called field motors, whose efficiency is increased by the magnet coating process. The treatment also reduces friction resistance in the mobile suit's joints.

First tested on the RX-78-3 Gundam, this process is then applied to the RX-78-2 used by Amuro Ray, reducing the time required for changes of direction by roughly 27%. The RX-78-4, RX-78-5 and RX-78NT1 are also equipped with magnet coating, and during the Gryps Conflict this technology is used in transformable mobile suits to speed up the transformation process. [Gundam, Gundam 0080]

The technical term for a mobile suit's arm and hand. The mobile suit was originally conceived of as a powered space suit to extend the human operator's own capabilities, and the term "manipulator" is inherited from the artificial arms used in powered suits. These devices give the mobile suit unparalleled versatility, and their built-in touch sensors provide immediate feedback for precise operation. In some cases weapons and shields are also integrated into these manipulators, but their primary functions are carrying equipment and manipulating objects.

An electromagnetic catapult installed on the surface of a planet, moon, or other celestial body, which is used to accelerate objects to escape velocity. On a small celestial body like Earth's moon, with low gravity and no atmosphere, objects can be launched into orbit by the mass driver alone, but objects launched from Earth still require a rocket booster to complete their ascent.

Upon reaching its destination, the mass driver's payload can be collected by a giant net known as a mass catcher. This system is used to deliver resources mined from the lunar surface to the Lagrange points, where they can be used for space colony construction. [Char's Counterattack]

The most powerful class of beam weapon used by mobile suits. The mega launcher is a large mega particle cannon with firepower exceeding that of a warship's guns, which draws its power from a built-in thermonuclear reactor. Though mega launchers are equipped with maneuvering verniers, their sheer bulk reduces the mobility of the mobile suits that carry them, and due to their high power requirements they must spend a considerable amount of time charging up prior to each shot. To speed up this recharging process, additional mobile suits can be connected to a mega launcher to serve as energy tanks.

Examples of this type of weapon include the mega bazooka launcher used by the MSN-00100 Hyaku Shiki, and the hyper mega launcher used by the MSZ-006 Zeta Gundam. [Zeta Gundam]

The standard beam weapon of the Universal Century era. When positive and negative Minovsky particles are compressed, they fuse into a new subatomic particle called a mega particle. In the process, a portion of their mass is converted into kinetic energy, giving the mega particle a high initial velocity. These fast-moving mega particles can then be focused into a devastating energy beam.

The mega particle cannon is a formidable weapon. Its energy conversion efficiency is more than four times that of a laser, and since the mega particles are electrically neutral, they are far harder to deflect than a conventional charged particle beam. However, the device's electrical power consumption is very high, and it requires a steady supply of Minovsky particles. As a result, these weapons can initially be used only by warships, mobile armors, and amphibious mobile suits with large water-cooled thermonuclear reactors. After the development of the energy capacitor (E-CAP), the mega particle cannon - in the form of the beam rifle - becomes the standard weapon of all mobile suits.

This special feature of the F91 Gundam is a byproduct of the Multiple Construction Armor concept. In addition to its radiators and cooling ducts, the F91 can also dissipate excess heat by shedding the outer layers of its armor. This process creates afterimages of the mobile suit made up of metallic particles, which can deceive not only the eyes of enemy pilots, but also radar and other sensors. [Gundam F91]

A lift-generating system which allows a vehicle to resist the pull of Earth's gravity. When Minovsky particles are released into the air, the positive and negative particles spontaneously align themselves into a three-dimensional cubic lattice. Because of the repulsive and electrostatic forces between the Minovsky particles, this lattice resists compression, and the Minovsky craft system uses this phenomenon to push the underside of the vessel away from the planet's surface.

Though the Minovsky craft system doesn't produce genuine anti-gravity, it does allow a vehicle to float over Earth's surface. Since the lattice of Minovsky particles it generates beneath the vessel repels plasma and ionized gases, this system also provides some protection from the heat of atmospheric entry. During the One Year War, the Minovsky craft system is employed by Pegasus-class assault carriers like the White Base, and by the mobile armors Adzam and Apsalus. However, the system's high power requirements and sheer bulk prevent its installation in a standard mobile suit.

A new kind of subatomic particle discovered by the scientist Y.T. Minovsky. The Minovsky particle has near-zero rest mass, and either a positive or negative electrical charge. When these particles are scattered in the air or in open space, they disrupt low-frequency electromagnetic radiation like microwaves and radio waves, and interfere with the operations of electronic circuitry. This phenomenon renders radar detection and long-range wireless communication useless, and requires the installation of bulky and expensive shielding on all electronic equipment, ruling out the use of precision guided weapons. The military use of Minovsky particles thus ushers in a new era of close-range combat.

Minovsky particles have some other unique characteristics as well. When scattered, they align themselves into a three-dimensional cubic lattice. Due to the repulsive and electrostatic forces between the Minovsky particles, this lattice functions as a kind of a force field, which is referred to as an I-field. And when such a lattice is compressed, the positive and negative Minovsky particles fuse into electrically neutral mega particles, which can be focused into devastating energy beams.

A new scientific field pioneered by Doctor Y.T. Minovsky. In U.C. 0045 this scientist founds the Minovsky Physics Society in the space colonies of Side 3, and goes on to develop a functional thermonuclear fusion reactor. In U.C. 0065 Minovsky notices a unique electromagnetic effect within the completed reactor, which he attributes to a new kind of subatomic particle. The existence of this Minovsky particle is proven in U.C. 0069, validating Minovsky's theories and ushering in a new era of particle physics.

Minovsky's discoveries are soon turned to military applications. In U.C. 0070, the researchers of the Principality of Zeon successfully use Minovsky particles to disrupt electromagnetic waves, and construct a working mega particle cannon. A new type of ultracompact thermonuclear reactor, developed the following year, later serves as a power source for the Principality's mobile suits. Minovsky himself, dismayed by the policies of the Principality's leaders, defects to the Earth Federation in U.C. 0072. Thanks to his assistance, the Earth Federation Forces then begin catching up to the Principality's technology.

Before the advent of the Minovsky particle and its disruptive effects, missiles were usually rocket-propelled weapons with built-in guidance systems. But with radio waves blocked by the Minovsky effect, missiles can't be guided by radar - and since Minovsky particles also disrupt electronic circuits, even computer-guided missiles can't function without bulky and expensive shielding equipment. As a result, during the One Year War missiles are essentially reduced to unguided rockets. After the war, the development of guided missiles becomes possible again, thanks to advances in optical circuitry and visual homing systems.

A large, non-humanoid variety of mobile weapon. When the Principality of Zeon sets out to develop a new type of space combat vehicle for the era of the Minovsky particle, one of the proposals considered is a high-speed spacecraft equipped with manipulator arms and armed with a mega particle cannon. Though this concept is ultimately rejected in favor of the more versatile mobile suit, the idea is later resurrected in the experimental mobile armors that appear at the end of the One Year War.

Though they lack the adaptability and melee combat capabilities of mobile suits, mobile armors far surpass them in terms of mobility and firepower. Their sheer size allows mobile armors to carry large reactors and drive powerful beam weapons, and they can also house bulky devices like psycommu systems, I-field generators, and Minovsky craft systems.

An older type of spacecraft, derived from the space worker pods used before the introduction of the mobile suit. The RB-79 Ball, a spherical fighting vehicle equipped with maneuvering verniers and manipulator arms, is a classic example of the mobile pod. Another example is the Med which Hathaway Noa uses to stow away aboard the Londo Bell flagship Ra Cailum. [Gundam, Gundam 0083, Char's Counterattack]

A highly maneuverable humanoid fighting machine, designed for short-range combat in an era where the Minovsky particle has made radar obsolete. The typical mobile suit stands about 60 feet tall - ten times human size - and is operated by a single pilot from a cockpit in its torso. While the first mobile suits are created for space combat, the basic design proves flexible enough to be adapted for land and sea warfare as well.

A general term which encompasses mobile suits, mobile armors, and any other machines based on the same technology. This term is often employed for devices, like the armed base Orchis used by the RX-78GP03 Gundam, which otherwise defy classification.

The distinctive main sensors used by the mobile suits of the Principality of Zeon, which resembles the eye of a giant cyclops. In addition to an optical camera, this compound device also incorporates laser and infra-red sensors for precision targeting. The mono-eye is mounted on rails, and can slide back and forth to cover a wide field of view. The visual data provided by the mono-eye is supplemented by ten or more secondary cameras, which are distributed around the exterior of the mobile suit.

A new concept in mobile suit construction which is introduced after the One Year War. Early models of mobile suit are based on a rudimentary internal frame, enclosed within an outer layer of sturdy armor. But with the introduction of the beam rifle, conventional armor becomes almost useless, and designers begin reducing their mobile suits' armor to the bare minimum in order to improve their maneuverability. This process eventually leads to the movable frame, a concept which is pioneered by the RX-178 Gundam Mk.II and becomes the universal standard during the Gryps Conflict.

Rather than merely serving as a structural framework, the movable frame incorporates all the mobile suit's vital mechanisms, including the actuators and control systems required for movement. In short, the movable frame includes everything except the mobile suit's weapons, armor, and propellant tanks. This approach dramatically improves the mobile suit's responsiveness, reliability, and energy efficiency, as well as making it far more agile than traditional designs.

A new design concept used in the construction of the F91 Gundam. In this approach, a variety of functions are incorporated into the mobile suit's armor layers. In addition to providing protection, the F91's armor also incorporates circuitry and cooling systems, allowing this highly compact mobile suit to make more efficient use of its limited internal space. [Gundam F91]

An advanced type of psycommu system developed by the Crossbone Vanguard commander known as Iron Mask, and installed in the mobile armor XMA-01 Rafflesia. Using this mind-machine interface, Iron Mask can operate the Rafflesia via thought alone, without the use of any conventional levers, pedals, or manual controls. [Gundam F91]

A traditional space suit used for extravehicular activities, so named to distinguish it from mobile suits. The normal suit includes life-support and communications equipment, and can be fitted with a vernier backpack for zero-gravity maneuvering. There are several different varieties, including a lightweight version designed for pilots called a pilot suit.

A new type of cockpit display, typically used in conjunction with a linear floating seat. The multiple panels of the panoramic screen make up a single 360-degree display, which covers the entire inner surface of the spherical cockpit. The image displayed on this screen is a computer simulation constructed from the cameras distributed around the mobile suit's exterior. The viewpoint is that of the mobile suit's head, and the image is carefully edited to remove the mobile suit itself.

This system is introduced during the One Year War and experimentally employed in the RX-78NT-1 Gundam, but it doesn't enter mass production until U.C. 0085. By the time of the Gryps Conflict, the panoramic screen and linear floating seat have become standard equipment for all mobile suits.

Even before the introduction of the mobile suit, powered suits and worker pods were used for mundane tasks like space colony construction. In later years, as military mobile suit technology makes its way into the civilian sector, scaled-down mobile suits are developed to fill this role. Petit mobile suits, the most common variety, stand about four or five meters tall and have pressurized cockpits, allowing the operator to work in space without wearing a protective normal suit. In addition to colony maintenance and salvage work, these machines are also used for military tasks like space colony defense and combat engineering. [Gundam 0080, Char's Counterattack]

A lightweight type of normal suit designed for combat pilots. These form-fitting space suits provide a minimum of impediment to the pilot's movements. Only a handful of reckless pilots, like Char Aznable, Paptimus Scirocco and Haman Karn, are willing to forfeit the protection of the pilot suit in order to avoid this minor inconvenience.

The reaction mass used in the rocket engines of mobile suits and other spacecraft. When this propellant is discharged through the rocket nozzles, it creates a counter-force in the opposite direction, generating thrust. The amount of thrust depends on the exhaust velocity and the rate at which propellant mass is consumed, and since the former factor is subject to strict technological constraints, mobile suits must carry large quantities of propellant to sustain them throughout extended battles. Due to internal space limitations, some mobile suits carry additional propellant in external tanks.

An external tank used for propellant storage. This extra propellant greatly extends a mobile suit's operating range, and enables it to stay in combat longer. When the propellant is consumed, the tank can be discarded to reduce the mobile suit's weight. These tanks use a two-layered construction, with one layer containing propellant, and the other holding extra coolant.

The mobile suits and vehicles of the Universal Century use a variety of propulsion mechanisms. The most basic is a chemical rocket engine similar to those used in modern spacecraft, which uses a chemical reaction to ignite its propellant and generate thrust. A more efficient alternative is the thermonuclear rocket engine, which uses the thermal energy of a fusion reactor to heat the propellant to a far higher temperature than in a chemical rocket. The greater temperature means higher exhaust velocity, so the thermonuclear rocket requires less propellant to obtain a given amount of thrust. This is the standard propulsion system used in mobile suits and space warships.

The basic principle of the thermonuclear rocket engine can be used in other types of propulsion system. The thermonuclear jet engine draws in air from the atmosphere, and heats it to create thrust. Similarly, amphibious mobile suits use a thermonuclear hydrojet engine which runs on water. Some mobile suits and vehicles are even equipped with hybrid engines which can function as either rockets or jets, consuming propellant or air as circumstances permit.

This technology allows a mobile suit to be externally controlled via the psycommu system. Developed by the Earth Federation's Newtype Labs, this system is first installed in the second unit of the MRX-009 Psyco Gundam, and is a standard feature of the MRX-010 Psyco Gundam Mk.II. The technology is later obtained by the renegade Principality of Zeon soldiers based at the asteroid Axis. [Zeta Gundam]

A design approach in which microscopic psycommu receiver circuits are installed throughout a mobile suit's internal frame and cockpit walls. These tiny circuits amplify and transmit a Newtype pilot's thoughtwaves, enabling the mobile suit to respond instantaneously to mental commands. While the mobile suit still requires additional hardware to complete the psycommu system, this distributed design is far more space-efficient than previous types. First introduced in the Neo Zeon mobile suit MSN-04 Sazabi, this technology is subsequently leaked to Anaheim Electronics and incorporated into the RX-93 Nu Gundam as well. [Char's Counterattack]

During the One Year War, the researchers of the Flanagan Institute discover that Newtypes emit powerful thoughtwaves - similar to regular brainwaves, but not electrical in nature - which they call psycho-waves. The Flanagan Institute goes on to develop a mind-machine interface called the psycommu (psycho-communicator) system, which receives these thoughtwaves and translates them into computer commands. Using this interface a Newtype pilot can direct remote weapons, and operate huge mobile armors, by thought alone.

After the One Year War, both the Earth Federation Forces and renegade Principality of Zeon soldiers continue the Flanagan Institute's research. The Principality forces based at the asteroid Axis succeed in miniaturizing the psycommu system, so that it can be installed in regular-sized mobile suits like the AMX-004 Qubeley. The Federation Forces, meanwhile, concentrate on developing artificially enhanced cyber-Newtypes to operate their psycommu weapons.

A mind-machine interface, based on the psycommu system used by Newtype, which can be used even by normal humans. Rather than sending and receiving data via thoughtwaves as in a true psycommu system, the quasi-psycommu system continually samples the pilot's electrical brainwaves, allowing the pilot to communicate specific instructions almost instantaneously. This system permits the use of simple remote weapons like incoms, but even with computer support, these devices are capable only of two-dimensional movement.

The quasi-psycommu system is still under development during the Gryps Conflict. Though it's the subject of ongoing research by the renegade Principality of Zeon soldiers at the asteroid base Axis, at the point when Axis returns to the Earth sphere their efforts have yet to bear fruit.

A device that uses a powerful I-field to redirect mega particle beams. Reflectors use the same basic concept as a protective I-field generator, but rather than scattering enemy beams, reflectors intercept beams fired from the operator's own weapons and deflect them in the desired direction. Using these devices, a mobile suit or mobile armor can concentrate fire from multiple weapons, or launch attacks from unexpected angles. While a defensive I-field generator requires a continuous supply of electrical power, the reflector's I-field can be synchronized with the firing of other weapons, and briefly activated to redirect their beams. These devices can be installed in remote weapons like bits and incoms, and the MRX-010 Psyco Gundam Mk.II was originally intended to carry a complement of reflector bits for this purpose.

This device sprays a sticky sealant, similar to the wall film used to mend breaches in warship hulls. This substance can be used to seal ruptures in spacecraft and space colony exteriors. By the time of the Gryps Conflict most mobile suits have sealant launchers built into the fingers of their manipulators, as well as utility devices like signal flares, dummy dispensers, and fire extinguishers. [Zeta Gundam]

Thanks to the effects of Minovsky particle interference, radar sensors are virtually useless in the battlefields of the Universal Century, and optical cameras are the primary means of detecting and targeting enemy vessels. These are supplemented by infra-red and laser sensors for precision targeting.

Infra-red sensors can also be used for long-range enemy detection. Although Minovsky particle interference does have some effect at infra-red wavelengths, enemy warships and mobile armors still register as heat sources. On Earth, other options for detecting enemies include sonar and magnetic anomaly detectors - the latter devices, used in the modern era for locating submarines, sense the magnetic distortions caused by metallic objects.

Though it's still possible that a battle might be fought without either side scattering Minovsky particles, this is an extremely rare situation. Mobile suits are still equipped with radar systems, but these are used primarily for measuring the Minovsky particle density in the surrounding area.

With the development of a new generation of highly compact mobile suits after U.C. 0100, designers begin to consider shifting systems like generators and thrusters outside the mobile suit itself. The shelf nozzles installed on Crossbone Vanguard command mobile suits like the XM-04 Berga Dalas and XM-05 Berga Giros are examples of this external device concept. These shelf nozzles are movable thrusters attached to the mobile suit's backpack, whose flexibility also allows them to be used for AMBAC maneuvering. [Gundam F91]

An extra plate of armor carried on a mobile suit's arm. A skilled pilot can use this crude device to deflect enemy attacks, but in the hands of a novice it's little more than dead weight, so designers sometimes opt to omit the shield and devote the equivalent mass to heavier armor for the mobile suit itself.

A shock-absorbing device which becomes a standard feature of mobile suit cockpits around U.C. 0090. Numerous shock absorbers are installed throughout a mobile suit's body, and the linear floating seat where the pilot sits is itself mounted on an electromagnetic shock absorber. The shock balloon, an inflatable cushion similar to the airbags in modern automobiles, provides additional protection in the event of violent deceleration. The balloon emerges from the cockpit's console panel at the moment of impact, and then immediately deflates again. [Char's Counterattack]

A fixed weapon installed in the left arm of the Crossbone Vanguard mobile suit XM-03 Ebirhu S. Not only can it be used in melee combat, but the entire device or its individual claws can also be launched like missiles. [Gundam F91]

A distinctive weapon used by Crossbone Vanguard mobile suits, whose resemblance to the lance of a medieval knight suits the Crossbone Vanguard's chivalrous image. This weapon is designed for combat in and around space colonies, where beam weapons would run the risk of triggering catastrophic reactor explosions in enemy mobile suits. Instead, the shot lancer uses electromagnetic acceleration to drive its tip through the enemy's armor, and the spearhead itself can also be launched like a missile. [Gundam F91]

A nickname for the Sub Flight Systems introduced after the One Year War. These devices are flying platforms which can carry one or two mobile suits, giving them extended range in space and flight capabilities in Earth's atmosphere. During the Gryps Conflict and the Neo Zeon rebellion of U.C. 0093, these sleds are used by every warring faction, including the Earth Federation Forces, the Titans, the AEUG and the Neo Zeon. [Zeta Gundam, Char's Counterattack]

A strategic weapon used by the Earth Federation Forces in their attack on the space fortress Solomon. Like the weapon devised by the ancient inventor Archimedes, this array of mirrors focuses the sun's light into a single devastating point, capable of carving through solid rock. The Solar Flare System consists of four million individually adjustable mirrors, computer-coordinated to form an immense lens tens of kilometers across. [Gundam]

In the Universal Century era, most of Earth's electricity supply is provided by solar power stations placed in a satellite orbit around the planet. These satellites efficiently convert sunlight into electrical power, then transmit it down to receiver stations on the planet's surface in the form of microwaves. [Zeta Gundam]

The ultimate weapon of the Principality of Zeon. The Solar Ray System consists of an entire space colony converted into a giant laser cannon, which is capable of blasting an enemy fleet at a range of tens of thousands of kilometers. Its energy requirements are massive - equivalent to a few hours' worth of Side 3's entire electrical supply - and its key components are still in the testing stage, so for all practical purposes the Solar Ray can only be activated once. [Gundam]

A refined version of the Solar Flare System used at the Battle of Solomon, which is deployed by the Earth Federation Forces in U.C. 0083 to stop a runaway space colony. The Solar System II consists of only 408,000 mirrors, but thanks to improved materials and more sophisticated control software, its destructive power is equal to that of the original. [Gundam 0083]

In case of emergency, the inhabitants of a space colony can escape using small spacecraft stored in the colony's outer walls. These space boats can hold more than a dozen passengers each, in addition to two pilots, and are equipped with handy manipulator arms. [Gundam F91]

The characteristic spiked shoulder armor of the MS-06 Zaku II, which is also seen on several other Principality of Zeon mobile suits. This device can be used to perform ramming attacks and pierce enemy armor.

A detachable booster installed on the Neo Zeon mobile armor NZ-333 Alpha Azieru in place of legs. These devices house both propellant tanks and powerful rocket thrusters, enabling the mobile armor to accelerate rapidly on its way to the battlefield. Once their propellant is exhausted, the sturm thruster units are detached and discarded as dead weight. [Char's Counterattack]

During the One Year War, the Principality of Zeon adapts the Dodai bomber into a flying platform for transporting mobile suits through Earth's atmosphere. But the Dodai also retains all the functions of a conventional aircraft, such as navigation and fire control systems, and requires its own dedicated pilot. This makes the Dodai highly versatile, but also rather expensive.

After the war, the Earth Federation Forces refine this concept into a dedicated mobile suit support device, substantially reducing its cost. These Sub Flight Systems, or sled, come in both atmospheric and space versions. During the Gryps Conflict, they are often unmanned models controlled by the mobile suit itself, but later versions are equipped with cockpits so that they can also be used as transport craft. [Zeta Gundam, Char's Counterattack]

An elongated, movable binder installed on a mobile suit's back. This tail stabilator serves to increase the mobile suit's maneuverability, thanks to its built-in vernier thrusters and its AMBAC capabilities. The MSZ-006 Zeta Gundam, RX-139 Hambrabi, PMX-003 The O, and RGZ-91 Re-GZ are among the mobile suits equipped with these devices. [Zeta Gundam]

A unique weapon used by the Crossbone Vanguard mobile armor XMA-01 Rafflesia. These tentacles can be used to grapple enemy mobile suits, and they are also tipped with small beam guns and lethally effective chainsaw blades. [Gundam F91]

A highly efficient propulsion system used for moving asteroids, space colonies, and large vessels like Inter-Planetary Helium Carriers. In this mechanism, fuel pellets composed of deuterium and helium-3 are bombarded by powerful lasers or particle beams, creating a series of tiny fusion explosions. The protons and helium ions produced by these fusion reactions can then be directed by a magnetic field to generate thrust. This mechanism has far better fuel efficiency than a thermonuclear rocket engine or a chemical rocket, but due to its relatively low thrust it's best suited for massive, slow-moving objects. [Zeta Gundam, Char's Counterattack]

A high-temperature fusion reactor which produces electrical power via a generator, and whose heat energy can be used to run thermonuclear rocket engines. The thermonuclear reactors of the Universal Century employ a deuterium-helium-3 reaction which generates virtually no neutrons, eliminating the need for bulky radiation shielding.

In U.C. 0071, this fusion technology is further refined to create an ultracompact high-output model, which uses a powerful I-field to confine the plasma inside the reactor. Three years later, this ultracompact thermonuclear reactor is chosen as the power source for the Principality of Zeon's prototype MS-04 mobile suit, and it goes on to become the standard power source of all mobile suits, mobile armors, and combat spacecraft.

A similar concept to the transformable mobile suit (TMS). The distinction between TMS and TMA appears somewhat arbitrary, though the latter are often larger and more powerful. Of the transforming mecha used in the Gryps Conflict, only the PMX-000 Messala, NRX-044 Asshimar, ORX-005 Gaplant, NRX-055 Baund Doc, MRX-009 Psyco Gundam and MRX-010 Psyco Gundam Mk.II are classified as transformable mobile armors. [Zeta Gundam]

A new type of mobile weapon, introduced during the Gryps Conflict, which combines the versatility of a mobile suit with the specialized fighting capabilities of a mobile armor. Changing into its mobile armor form gives the machine higher speed and mobility, and allows it to perform feats like atmospheric entry. However, their transformation mechanisms make these transforming mobile suits complex and expensive, so - with the exception of the Gaza series produced at the asteroid Axis - the concept is never used in mass production. [Zeta Gundam]

A heavy weapon mounted on the back of the F91 Gundam. This weapon can fire either high-velocity mega particle beams for greater penetrating power, or low-velocity beams for maximum damage. The VSBR's output rivals that of a warship's main cannon, and in its high-velocity setting, it's capable of piercing even a beam shield. The F91's two VSBR units are movable devices which slide forward along their mounting rails into firing position; when not in use, they can also be employed for AMBAC maneuvering. [Gundam F91]

In addition to their main rocket engines, mobile suits and other spacecraft are also equipped with secondary rockets called vernier thrusters. These devices, distributed across the machine's outer surface, are used for changing direction and performing fine movements - or attitude control, in technical jargon. These verniers are sometimes referred to by the nickname "apogee motor."

A multi-barreled machine gun used as a fixed weapon in many mobile suits and space fighters. An electric motor spins the vulcan gun's chambers as they fire, enabling the weapon to sustain a rate of fire of 500 to 2000 rounds per minute. The vulcan guns used by mobile suits are relatively large, with 60mm being a popular caliber, but they're neither accurate nor highly effective against mobile suit armor. As a result, they're used mostly as defensive weapons in close combat.

A vulcan gun turret installed in the head of the RMS-099 Rick Dias. This weapon borrows its name from the close-in weapons systems used by modern-day naval vessels, which are in turn named after the massed phalanx formations of ancient Greek infantry soldiers. [Zeta Gundam]

A device that generates lift from shock waves like those produced during atmospheric entry. While a normal aircraft obtains lift from the difference in airflow speed between the upper and lower surfaces of its wings, a wave rider flying at supersonic speeds concentrates the shock waves under its lower surface and obtains lift from the resulting pressure, essentially riding on these shock waves. This principle is used in the flying armor employed by the RX-178 Gundam Mk.II, and in the transforming MSZ-006 Zeta Gundam. [Zeta Gundam]

The MSN-00100 Hyaku Shiki is equipped with a pair of distinctive binders which resemble aircraft wings. Since the Hyaku Shiki was originally meant to be a transformable mobile suit, its developers designed these binders so that they could move effectively even in its mobile armor form. [Zeta Gundam]

A handheld device which helps humans get around in zero-gravity environments like spacecraft hangars and space colony docks. The wire-gun launches a powerful magnet attached to a wire cable, which anchors the user in place and can be rewound to pull him to his destination. This device can also be used to establish a contact link for voice communication.
