The AMS-123X-X Moon Gundam is the titular mobile suit of Mobile Suit Moon Gundam. It is piloted by Jutta Qasim. The AMS-123X-X Moon Gundam is the AMS-123X Varguil equipped with a Gundam-type head and repainted in tricolor scheme. Additionally, the backpack's funnel rack has been completely removed and a sub-arm has been added to mount the Psycho Plates. The Psycho Plates is a Psycommu armament that drifted to Moon Moon along with the head.

The RGM-79GS GM Command Space Type is a mobile suit introduced in the OVA Mobile Suit Gundam 0080: War in the Pocket. Following the success of the RGM-79D GM Cold Districts Type, a late production type GM deployed in the One Year War, development of new localized warfare machines using the suit as a basis started. The basic concept is to maintain the fundamental design of the GM Cold Districts Type while improving on its output and mobility. Demands of MS pilots who were unsatisfied with the original RGM-79 GM's performance were also taken into account, and with the upcoming counter offensive in space against the Principality of Zeon in mind, a decision was made to simultaneously developed a ground use unit and a space use unit. The end results were the space use GM Command Space Type, and the ground use RGM-79G GM Command. Both suits were also used to collect data for the development of next-generation mass production models.Specifications wise, the GM Command series is said to be a match for the Zeon's MS-14A Gelgoog, but as many of the machines were deployed to areas outside of the main battlefield that had low urgency, its functions were often suppressed and it could not display its full potential. To improve on the GM Cold Districts Type’s mobility, the GM Command series’ thrusters are distributed all over its body. Furthermore, the backpack, which contains the main propulsion system, was also boldly redesigned and optimized separately for the GM Command Space Type and GM Command. This difference in the backpack is the biggest characteristic that differentiates the two machines, and is related to the different gravitational environment that they operate in, 0G and 1G respectively. While the GM Command had downward-pointing thrusters concentrated on the bottom of the backpack, the GM Command Space Type's thrusters are spread around the backpack and faces various directions. The GM Command Space Type's thruster output is also boosted by 10%, has more apogee motors, as well as a greater propellant capacity for higher operating time.With the GM Command series use of a generator with higher output, intakes and ducts are also added to enhance cooling functions. This higher output generator is however a double-edged sword. Although it allows for full-scale operation of equipment like beam gun and beam rifle, such generators at that time could only be manufactured in zero gravity facilities, so mass production of the suit then at the Earth Federation Forces’ largest production facility at Jaburo was not possible. This had a negative impact on the suit's production number during the war.Due to the accumulation of manufacturing and designing knowledge, the GM Command series' maintainability and operability was greatly improved compared to the very first mass production models that had inconsistent standards. Unlike the normal GM, the GM Command series has additional sensors in the head such as environment monitoring sensors to thoroughly detect human presence/survivability, and this boosts the suit's anti-personnel and anti-material evasive capabilities. The GM Command series is also the first in the GM series to utilize the mono-eye camera in the head to improve producibility. Communication capabilities are enhanced via the shoulder antenna, which also helps to prevent interferences or jamming caused by frequency bands used by civilians inside and outside of colonies. It was relatively easy to change the GM Command series' armor, backpack, and other parts; furthermore, its specifications can also be changed with little modification to the base structures.As the GM Command series was deployed as replenishment units during the war, only a small number were produced. Assignment of the machine to experienced MS pilots was prioritized, and as these pilots were often appointed as commanders of newly formed MS platoon, the GM Command series also gained a reputation as a 'Commander Use Unit' even though it was not specifically built for commanders. There were also cases where the suit was supplied on a platoon scale, leading to a considerable number of operational units in total.

The MS-06R Zaku II High Mobility Type (Reuse "P" Device) (aka Psycho Zaku) is a prototype mobile suit from the manga Mobile Suit Gundam Thunderbolt and its animated adaptation. It is piloted by Daryl Lorenz.The MS-06R Zaku II High Mobility Type (Reuse "P" Device) is a mobile suit operated by the Zeon army's Living Dead Division. An experimental unit equipped with the “Reuse P (Psycho) Device” - a next generation operating system that has the potential to operate a mobile suit's limbs by communicating to the drive system of the mobile suit directly via thoughts. Even individuals with little piloting experience can master the controls in a short period due to this system. Although Ensign Daryl Lorenz is the pilot of the Psycho Zaku and his main mission is to snipe from ultra-long ranges, to pilot the unit, a high proficiency of control is necessary. It is believed that some training time is necessary, however it was pressed into combat so the training was cut extremely short thanks to the device. In order to draw out 100% of its abilities, the pilot must be quadruple amputee to fully interface with the mobile suit.

The RX-0 Unicorn Gundam (ユニコーン ガンダム Yunikōn Gandamu?, or Unicorn, Unicorn Gundam 01, Singularity One) is the titular prototype mobile suit of the Mobile Suit Gundam Unicorn novel, its OVA adaptation and the television re-cut. Developed by Anaheim Electronics for the Earth Federation, it concealed a secret that could shake the future of all humanity, for it was the key to opening Laplace's Box. It is piloted by Banagher Links after the head of the Vist Foundation and his father, Cardeas Vist, entrusted it to him at the dawn of the Third Neo Zeon War in U.C. 0096.Produced as the final part of the E.F.S.F's reorganization plan, the "UC Project", the Unicorn Gundam is a revolutionary design meant to be the main symbol of the project's main goal: to destroy any traces of Zeonism in the Earth Sphere. Thus, not only does it feature a Gundam design, but it also incorporates an anti-Newtype system. Two prototype machines were completed at Anaheim Electronics' factory in Granada. However, when the Vist Foundation took control of the project, they installed a special "La+ Program" OS into the Gundam, turning it into a symbol of possibility by making it the key to finding Laplace's Box: the embodied hope of the Universal Century. Featuring the most advanced mobile suit technology of the time, its performance is unmatched.Incorporating test data from the experimental MSN-06S Sinanju Stein, the Unicorn Gundam's entire frame is built with Psycho-Frame material, drastically increasing the unit's responsiveness and allowing it to be piloted like an extension of the pilot's body. While mobile suits used during the Second Neo Zeon War implemented psycho-frame technology on a limited basis, the Unicorn is the first "full psycho-frame" mobile suit. In some cases, this responsiveness is so high that the machine appears to act on its own without any actions from the pilot. In addition, the Unicorn utilizes a special system known as the "NT-D" (or Newtype Destroyer) which activates the suit's psycho-frame and dramatically increases the suit's performance.In its normal form, the "Unicorn Mode", the Unicorn Gundam's head is similar in appearance to those of Londo Bell's mass-produced mobile suits, with the addition of a single, horn-like antenna on its forehead (which gives it the name "Unicorn"). Destroy Mode is the form when Unicorn Gundam's NT-D System is activated. The transformation is marked by an expansion of the suit's frame. The armor seams separate and lock down into various hard-points, while the newly exposed psycho-frame emits a pinkish-red or greenish (Awakened) glow (attributed to the Psycho-Field phenomenon). In this mode, the Unicorn becomes taller, reveal six more thrusters, and its head transforms to one with standard Gundam features, the visor and face guard retracts into the head to reveal the twin eyes and mouth plate, and the antenna splitting into a V-fin. To prevent its transformation being interrupted, the strength of its I-Field will be increased temporarily. Additionally, a pair of sub-sensors are revealed on the shoulders, and two concealed beam sabers extend out of the backpack.In Destroy Mode, the suit's psycho-frame scans the pilot's thoughts and directly transmits them to the suit's drive system; in other words, the Unicorn can be controlled by the pilot's thoughts alone. Additionally, the mode also causes the machine's performance - in thrust, generator output, and sensory radius - to be increased to unmeasurable levels. The NT-D also allows the Unicorn to take control of an enemy's psycommu weapons (also known as "Psycommu Jack") by emitting a Psycho-Field. However, the stress placed on the mind by manipulating an object more than tenfold the size of an average human is extraordinary. Even with the aid of the psycho-frame, the pilot's mind can only endure roughly five minutes of operation before a limiter is activated, deactivating the psycho-frame and returning the mobile suit to its Unicorn Mode.With the performance limiters disengaged, the Unicorn can accelerate up to 20 G's in Destroy Mode; to alleviate such high levels of G forces placed on the pilot, a drug administration system called the "DDS" is fitted on the pilot suit. It suppresses stagnated blood circulation due to high acceleration by administering the drug to the pilot. Furthermore, the DDS activates automatically upon the detection of another Newtype via the "Intention Automatic System".

The MSM-07 Z'Gok (ズゴック Zugokku?) is a mass-production amphibious mobile suit introduced in the anime Mobile Suit Gundam. The Z'Gok is one of the heavy mobile suit developed by MIP. Like the MSM-04 Acguy, it is viewed as a second-stage amphibious MS, different from the MSM-03 Gogg, a first-stage unit. The Z'Gok's final design was improved based on actual combat data from the Gogg, but this delayed its development and the Acguy was completed before it.Among amphibious mobile suit, the Z'Gok's focus is on ground combat. Besides using both air and water-cooled radiators, it also has chemical fuel rockets for jumping in addition to thermonuclear water jets. The Z'Gok is also designed so that it can perform anti-air combat as well as search operations on and above the water surface, duties that the Gogg could not.The Z'Gok's specifications are superior to those of the mass production mobile suits by the Earth Federation Forces at the same period. However, in return for high performance, it is difficult to pilot. Furthermore, it is a costly machine because it lacks parts compatibility with the Gogg.

The MSM-03 Gogg is an amphibious mobile suit introduced in Mobile Suit Gundam. The Principality of Zeon had developed the ground use MS-09 Dom, but its nuclear reactor's output was insufficient for powering mega particle cannons/guns. Increasing the reactor output would require better cooling capacity, and the most efficient method was water cooling. Therefore, in November U.C. 0078, the MIP and Zimmad received orders to develop amphibious MS which can use seawater for cooling. In addition to the use of mega particle weapons, the amphibious MS can reach its destination by traveling through the sea on its own, allowing it to fight in areas away from Zeon's frontline bases.To reduce water resistance, the Gogg's head became a rounded streamline shape, the MS' equipment was internalized, and the limbs can be retracted when cruising underwater. The Gogg has long operating time in water, and relies on thermonuclear hydrojet engines that draw in water, then heat them with the high heat of the reactor to create thrust. When operating on land, cooling water is stored in internal ballast tank, and the mobile suit's operating time is limited to 1–2 hours. This shortened operating time on land is due to reactor cooling limitations. The Gogg is not an agile machine due to its weight, but its pressure-resistant design provides sufficient defense in close combat.The Gogg's design proved marginally successful, and about 300 units were produced according to one source.[1] However, it would be later replaced by more powerful and better designed amphibious mobile suits, such as the MIP's highly successful MSM-07 Z'Gok. Despite this, the Gogg served as a base design from which almost all other underwater combat mobile suits were derived.

The NZ-666 Kshatriya (クシャトリヤ, Kushatoriya), aka the "Quad-wing", is a mobile suit featured in the novel and OVA series Mobile Suit Gundam Unicorn. It was piloted by Marida Cruz. The Kshatriya was designed with the intention of miniaturizing the NZ-000 Queen Mansa - which was more than 40 meters tall - while retaining its performance. This was done through the implementation of new technology, including the installation of Psycho-Frame around its cockpit. Since Neo Zeon lost the ability to manufacture Psycho-Frame following the Second Neo Zeon War, the Kshatriya became a one-off unit. Another factor that contributed to its miniaturization was that most of its functions are concentrated in its four wings/binders. As a result, the Kshatriya was almost half the size of its predecessor. The four massive wings/binders are also the Kshatriya's greatest features, each containing two mega particle cannons, a funnel container with six funnels, an I-Field generator, flexible thrusters, a propellant tank, and a sub-arm equipped with a small beam saber. Each wing/binder also serves as an AMBAC unit. Like its predecessor, the Kshatriya requires a powerful Newtype pilot.

The RX-79[G]Ez-8 Gundam Ez8 is a customized RX-79[G] Gundam Ground Type introduced in the OVA Mobile Suit Gundam: The 08th MS Team and is piloted by the main protagonist Shiro Amada. During the battle with the Apsaras II, Shiro Amada's Gundam Ground Type was heavily damaged, necessitating major repair and overhaul. Based on the combat data collected up until that point, as well as feedback from Shiro Amada himself, the Gundam received various modifications. The result became known as Gundam Ez8, short for "Extra-zero-8", which stood for "08th MS Team extra unit".The Ez8's chest armor received major changes. Its chest armor plating was made using two Zaku II shoulder shields welded together, which can flip open for easy maintenance and can withstand a direct hit from a Zaku II's 175mm Recoilless Rifle with only a few scratches. The multi-launcher and the chest-mounted vulcan gun were removed due to being considered unnecessary. Instead, a 12.7mm vulcan gun was mounted just below the chest armor.Due to high damage rates in the jungle, the Gundam's signature V-fin was replaced with a rod antenna mounted on the right side of the head. The snorkel camera was removed, and a pair of 35mm vulcan guns were mounted on either side of the head. Due to the lack of Luna Titanium armor material, extra armor was added to the forehead and around the chin for protection. Other changes include the addition of movable knee spikes, which ensure stability during firing, and an improved shield fitted with extra armor. Due to improved power balance, its backpack thrusters had a higher output despite being visually identical.Overall, as a result of the various modifications, the Ez8 was made lighter without significantly sacrificing durability. Though its basic performance was unchanged from the Gundam Ground Type, it was slightly superior in terms of mobility and communications ability.

The MS-05L Zaku I Sniper is a variant of the MS-05B Zaku I. It first appeared as a part of Harmony of Gundam variations design by Hajime Katoki, but was also featured in Mobile Suit Gundam Unicorn and Model Suit Gunpla Builders Beginning G. A retrofitted version of the MS-05 Zaku I, the MS-05L Zaku I Sniper Type's primary weapon was a beam sniper rifle, which was powered by a backpack-mounted sub-generator. Its head unit was fitted with the same type of composite monoeye as the MS-06E Zaku Reconnaissance Type, granting it the necessary sensor range for long-range sniping. It was also equipped with a pair of head-mounted Vulcan guns for defense. A foldable knee pad was installed in its right knee, which can deploy to stabilize the mobile suit during sniping missions. Essentially, the Zaku I Sniper Type was a self-propelled long-range mega particle cannon turret.

The MSM-07E Z'Gok-E (aka MSM-07E Z'Gok Experiment) is an experimental amphibious mobile suit introduced in the Mobile Suit Gundam 0080: War in the Pocket OVA . The Z'Gok E was an experimental improved version of the MSM-07 Z'Gok. Besides improved beam cannons in its arm, allowing for rapid-fire, the original Z'Gok's head-mounted missile launchers were also replaced with torpedo launchers for additional firepower when operating underwater. To allow for better cruising range underwater, the suit's main propulsion systems were relocated from the back to the legs to create a more streamlined body shape. Its limbs were also designed to be retractable for the same reason. The thrusters built into its back were meant for jumping and various ground based movements, and greatly boost the suit's mobility on land. The Z'Gok E used a standardized cockpit with the introduction of the United Maintenance Plan, and was powered by an improved generator which gave the suit ample performance.

The RGM-86R GM III is a mass-production general-purpose mobile suit introduced in the anime Mobile Suit Gundam ZZ. Its design was later updated for the novel and OVA Mobile Suit Gundam Unicorn. A mass-produced mobile suit of the Earth Federation Forces developed in accordance with the "GM III Plan" as a successor to the GM II. It was deployed as the main unit during the First Neo Zeon War. By actively introducing new technologies while maintaining productivity, some specs have acquired performance equal to or higher than Gundam Mk-II's. Its backpack is a mass production model of the Gundam MK-II's, and mobility and maneuverability have exceeded the level of existing mass production machines. Although this backpack has a slightly different shape, it maintains the same functions as the Mk-II's while improving cost performance, and the docking mechanism with the FXA-05D G-Defenser remains. The shoulders and waist can be equipped with missile pods and missile launchers, respectively, allowing the GM III to function as an MS for medium- and long-range support.

The RGM-79G GM Command is a mobile suit that first appeared in the OVA Mobile Suit Gundam 0080: War in the Pocket. Following the success of the RGM-79D GM Cold Districts Type, a late production type GM deployed in the One Year War, development of new localized warfare machines using the suit as a basis started. The basic concept is to maintain the fundamental design of the GM Cold Districts Type while improving on its output and mobility. Demands of MS pilots who were unsatisfied with the original RGM-79 GM's performance were also taken into account, and with the upcoming counter offensive in space against the Principality of Zeon in mind, a decision was made to simultaneously developed a ground use unit and a space use unit. The end results were the ground use GM Command, and the space use RGM-79GS GM Command Space Type. Both suits were also used to collect data for the development of next generation mass production models.The GM Command is also called the "Colony Type" as it specialized in defending bases in space colonies and surrounding areas. For this reason, its output and weaponry were adjusted to reduce fatal damage to the colony's structure and walls. Specifications wise, the GM Command series is said to be a match for the Zeon's MS-14A Gelgoog, but as many of the machines were deployed to areas outside of the main battlefield that had low urgency, its functions were often suppressed and it could not display its full potential. To improve on the GM Cold Districts Type’s mobility, the GM Command series’ thrusters are distributed all over its body. Furthermore, the backpack, which contains the main propulsion system, was also boldly redesigned and optimized separately for the GM Command and GM Command Space Type. The placements of the thruster verniers on the GM Command's backpack are optimized based on simulations of operation within colonies, and they are pointed downwards for movements under gravity. Various sensors are also added to the backpack, replacing the normal GM's backpack beam saber rack.With the GM Command series use of a generator with higher output, intakes and ducts are also added to enhance cooling functions. This higher output generator is however a double-edged sword. Although it allows for full-scale operation of equipment like beam gun and beam rifle, such generators at that time could only be manufactured in zero gravity facilities, so mass production of the suit then at the Earth Federation Forces’ largest production facility at Jaburo was not possible. This had a negative impact on the suit's production number during the war.Due to the accumulation of manufacturing and designing knowledge, the GM Command series' maintainability and operability was greatly improved compared to the very first mass production models that had inconsistent standards. Unlike the normal GM, the GM Command series has additional sensors in the head such as environment monitoring sensors to thoroughly detect human presence/survivability, and this boosts the suit's anti-personnel and anti-material evasive capabilities. The GM Command series is also the first in the GM series to utilize mono-eye camera in the head to improve producibility. Communication capabilities are enhanced via the shoulder antenna, which also helps to prevent interferences or jamming caused by frequency bands used by civilians inside and outside of colonies. It was relatively easy to change the GM Command series' armor, backpack, and other parts; furthermore, its specifications can also be changed with little modification to the base structures. The suit served as the base for the RGM-79SP GM Sniper II.As the GM Command series was deployed as replenishment units during the war, only a small number were produced. Assignment of the machine to experienced MS pilots was prioritized, and as these pilots were often appointed as commanders of newly formed MS platoon, the GM Command series also gained a reputation as a 'Commander Use Unit' even though it was not specifically built for commanders. There were also cases where the suit was supplied on a platoon scale, leading to a considerable number of operational units in total.

The RGM-79 GM (aka GM, pronounced Jim) was the first mass-produced mobile suit of the Earth Federation. It first appears in Mobile Suit Gundam. The RGM-79 GM is a mass-produced mobile suit based on the RX-78-2 Gundam. Its basic frame is easily adaptable to modifications into mission specific GM models, and has a fairly high level of mobility, for the time, both on Earth and in space. It has a maximum acceleration of 0.94 Gs in space, which is better than the Gundam's and roughly twice of the Zaku's. On Earth's surface, the GM is also faster than the Zaku II. The armor of the GM uses Titanium Alloy, a sturdy metal that could be refined more quickly and easily than the Gundam's Luna Titanium Alloy. Although titanium alloy is less durable than luna titanium, it is also slightly lighter which reduces the GM's overall mass compared to the Gundam's and is still superior to the Zaku II's super-high tensile steel armor.The GM was primarily armed with a beam spray gun, a less powerful version of the Gundam's beam rifle but could still destroy MS in one shot. Early in production, the beam spray gun had yet to be mass-produced so most GMs were equipped with various machine guns. These machine guns continued to be used by the GMs later, and the machine could also use the Gundam's beam rifle when required. It could also use a mass production version of the Gundam's Hyper Bazooka for heavier firepower. For close combat, the GM has a beam saber, and a shield similar to the one used by the Gundam. Commander units sometimes featured a second beam saber. Lastly, the GM has a pair of head-mounted 60mm vulcan guns for intercepting missiles, small vehicles or to stop enemy MS from closing in. From the GM started the RGM series that remained the mainstay of the Federation's mass production mobile suits until the end of the Federation itself.

The RX-77-2 Guncannon was a mobile suit used by the Earth Federation Forces introduced in the TV anime Mobile Suit Gundam. A middle-range support mobile suit developed simultaneously with the RX-78 Gundam and the RX-75 Guntank as part of Operation V, the Guncannon adopted the same Core Block System as the other two units. Due to its role as an artillery support unit, the Guncannon's design prioritized durability over mobility, and it was not equipped with any melee weapons. However, its armor was particularly heavy, capable of surviving a direct hit from an MS-09R Rick Dom's giant bazooka.Similar to the Guntank, the Guncannon's main weapons were a pair of shell-firing cannons, chosen for their reliability over beam weapons. These cannons could be optionally swapped out for a pair of spray missile launchers. Unlike the Guntank, however, the Guncannon's generator output allowed it to equip a beam rifle. It was also equipped with a pair of head-mounted Vulcan guns and hand grenades for attacking enemy strongholds.Though its head design appeared to be simpler than the Gundam's head, the Guncannon's sensor system was in fact more complicated than the Gundam's due to its need to engage in artillery warfare. This "twin eyes with goggles" sensor design were later inherited by the RGM-79 GM. While the Guncannon's mobility was adversely affected by its weight, it was still comparable to that of the Zeon's MS-06 Zaku II. Furthermore, the backpack thrusters have sufficient thrust to enable jumping maneuvers under gravity for a short period of time.

The MS-06FZ Zaku II Kai is a mobile suit introduced in the OVA Mobile Suit Gundam 0080: War in the Pocket. The Zaku II was one of the second-phase production MS that have been improved by the United Maintenance Plan. The performance of the Zaku II itself has begun to deteriorate due to the appearance of Federation MS and the development of new models by its own forces, so it has been tuned up by feeding back data from new models. In addition, based on the results of the renovation of the MS-06F-2 Zaku II F2 Type, the shape and materials of the armor and the balance of the machine were more thoroughly reviewed, resulting in an appearance that is quite different from the previous Zaku II F-Type.The most significant modification was to the cockpit, which is said to have been so good that even new recruits with insufficient training could handle it. In addition, the apogee motors in various parts of the fuselage and the thrusters in the backpack were increased and made larger, and the total thrust was increased by 70 percent compared to the previous F-Type model. On the other hand, the total amount of propellant had not changed, and the time limit at maximum combat thrust has dropped by half. The armor has also been considerably strengthened and the armament has been redesigned, so it does not lag behind the Federation's RGM-79 GM and has achieved considerable high performance. It also had the option of two different "helmet" designs. The "A-Type" helmet, which was the more common design, was similar to the typical helmet of the Zaku II series. The "B-Type" helmet, also known as "Fritz Helm" was modeled after the Stahlhelm helmet used by the German army in World War II. The Fritz helm was designed for pilots of downed machines to be able to remove the helmet dome and make repairs on their own.Rolled out one month before the end of the war, this machine is the final production model of the Zaku in the One Year War, but the number produced was small. It was only used by some units of the Space Fleet (especially the units made up of school soldiers and new recruits), and never landed on Earth, and it participated in few actual battles.

The RGC-83 GM Cannon II is a mobile suit introduced in the OVA Mobile Suit Gundam 0083: Stardust Memory. The successor of the RGC-80 GM Cannon, a medium-range support mobile suit developed in the late stage of the One Year War, the RGC-83 GM Cannon II was based on the RX-77D Guncannon Mass Production Type and inherited the Chobam Armor concept of the RX-78NT-1 Gundam NT-1. It was the culmination of the Federation's artillery support mobile suit development.Thanks to improvement in technology and productivity, the GM Cannon II was installed with a powerful generator, allowing it to be equipped with two shoulder-mounted beam cannons. This made it the first mass production unit to have high-powered beam cannons. These beam cannons were usually powered by the generator itself, but could also be powered by the two Energy CAP mounted on its backpack. A sighting device located on the pilot seat's headrest can be used to aim the beam cannons. For precision shooting under gravity, the stabilized gear on the waist could be deployed to stabilize the machine.The GM Cannon II's other weapons included a pair of head-mounted 60mm vulcan guns, a shortened beam saber stored in the left forearm, and the same GM Rifle and shield used by the RGM-79N GM Custom. Due to its role as a fire support mobile suit, the beam saber was only meant for close-quarters self-defense and it rarely had the chance to use it. The GM Cannon II also has relatively poor mobility due to the mass of its weapons and armor.The design of the GM Cannon II's basic components prioritized parts interchangeability with GM type mobile suits. Parts of its exterior was covered in composite armor, similar to the Chobam Armor used by the RX-78NT-1 "Alex". This composite armor improved bullet resistance while keeping the mobile suit's weight down. Unlike the Alex's Chobam Armor, the composite armor was built directly onto the frame and could not be purged when damaged. Despite their structural differences to Alex's armor, the composite armor was often referred to as "Chobam Armor" for convenience.Like the GM Custom, there was a plan to mass produce the GM Cannon II, but due to issues such as cost and the fact that the machine was meant to operate alongside the GM Custom, only a few units were actually deployed. After the Delaz Conflict, the project itself, including its development staff, was placed under the control of the Titans. The GM Cannon II's production was halted and a direct successor to it was never developed.

The RMS-106 Hizack (aka Hi-Zack) is a mass-production general-purpose mobile suit introduced in Mobile Suit Zeta Gundam. It was based on the MS-06 Zaku II series and was used by EFF groups, including the Titans, during the Gryps War. A mass-produced mobile suit developed at Granada with help from Anaheim Electronics, which absorbed the Zeonic Company which was once the major mobile suit developer for the Principality of Zeon. While the Hizack's external appearance resembles that of Zeon's famous Zaku II, it was a vast improvement over the older mobile suit. The Hizack's design incorporated both Earth Federation and Zeon technologies, with the latter contributing to it having the same high operating reliability and ease of production as the Zaku II. Data from the MS-06F2 Zaku II F2 Type was also referenced during development.The Hizack is outfitted with a titanium alloy ceramic composite armor and has a higher output generator than that of a Zaku. It is also faster and more agile than its predecessors and is easy to pilot. The Hizack is most often equipped with a 120mm machine gun kai, beam saber, or heat hawk. It sometimes uses a beam rifle, but due to its low generator output, it can only carry one beam weapon at a time. The Hizack can also be equipped with missile pods. Although the Titans were assigned to wipe out the remnants of Zeon forces, their Hizack uses a similar dark green color scheme. Meanwhile, the regular Earth Federation Forces used a dark blue color for their units.

The MSN-06S-2 Sinanju Stein is a mobile suit from Mobile Suit Gundam Narrative and is piloted by Zoltan Akkanen. The MSN-06S Sinanju Stein was developed to test the durability and follow-up capabilities of the Psycho-Frame. Two units of the Mobile Suit, referred to using the development code "Stein 01", were later stolen by The Sleeves, remnants of Neo Zeon. One unit was remodeled as the MSN-06S Sinanju and used as the flagship MS of the organization. In UC 0097, the other unit was seen in the fight over the RX-0 Unicorn Gundam 03 Phenex and was embellished with the engravings that became root for the name of The Sleeves.

The AMS-119 Geara Doga is a mass-production general-purpose mobile suit featured in Mobile Suit Gundam: Char's Counterattack and Mobile Suit Gundam Unicorn. The AMS-119 Geara Doga is a general purpose mobile suit with technology and design features descended from the old MS-06F Zaku II. It is developed based upon the design of an Axis machine taken out by members of Neo Zeon following the group's defeat at the end of the First Neo Zeon War. Since the resources of Char's Neo Zeon are limited, the Geara Doga was not a particularly high-performing unit when compared to the machines used by Haman Karn's Neo Zeon four years earlier; however, it was well in line with the style of mobile suit design of the day. Its performance was also sufficient for most soldiers, easy to mass-produce and remains a threat for the Earth Federation's own mass-produced suit, the RGM-89 Jegan..The Geara Doga has a wide variety of weapons to cope with different combat situations. Its only fixed armaments are a beam sword-axe for close combat and an shock anchor. It can be equipped with a shield with four grenade launchers and two different types of beam machine guns, with one capable of mounting additional weaponry. The Geara Doga is fitted with old Zeonic-style mono-eye head sensors able to detect targets at a longer range and thus make a faster offensive; however, when within combat range, the sensor's performance becomes limited in terms of target-tracking. The basic specifications of this machine is for space combat, and a backpack for long-distance cruising is standard equipment. With its versatility, maneuverability, and maintainability, the Geara Doga combines all the necessary factors as a practical weapon while earning the trust of mechanics and pilots in the field.

The RGM-79FP GM Striker is a ground close combat mobile suit and variation of the RGM-79C GM Type C.
