Export Policy:
Recent export permission has been given to Nineveh Armoured Works to supply an export version of the latest MCA-7 series tank, the G, to foreign interests. The MCA-7E, as it is known, is a fully capable MCA-7G, unlike the previous B-to-C modifications for export. No reductions in protection or capability were made to achieve the E, and only a limited number of modifications were made to the vehicle for export. The following writeup is for the MCA-7G, however the E model is completely identical in all aspects except for the following:
- The MCA-7E package does not include the An-1100H round for export.
- The MCA-7E computer systems have all been built with blank software around the standard systems. This means that the FCS or other systems can be configured to foreign languages and needs, while retaining all capabilities except one.
- The MCA-7E is unable to synchronize with the Sumerian Battle Network because of the previously mentioned computer construction, and safeguards in place. It can easily, however, be configured to work with local BattleNets.
The following ammunition is avalible for export under the conditions specified:
- An-1100A: Production rights come with vehicle purchase.
- An-1100B: Production rights come with vehicle purchase.
- An-1100C: Production rights come with vehicle purchase.
- An-1100D: Production rights come with vehicle purchase.
- An-1100E: Production rights come with vehicle purchase.
- An-1100F: Production rights come with vehicle purchase.
- An-1100G: Avalible for $32,000 USD per missile. ($1.6 billion DPR)
- An-1100H: Not Avalible for Export.
Spare parts production rights are avalible. It should be noted that all technology and equipment design integrated within the MCA-7E is property of the Sumerian government and is thusly copywritten. Any attempt to produce, in whole or in part, the MCA-7E or any of it's componants for export will be reciprocated with actions as deemed fit, up to and including military action.
Further, we wish to issue the following disclaimer: Nineveh Armoured Works, nor the Sumerian government or any of the subcontractors involved in the MCA-7 program can be held responsible for the quality of work by foreign producers under domestic production rights. While we strive to aid foreign industry to the quality demanded by the MCA-7, we hold no responsability in their construction.
We thank you for reviewing the MCA-7E, and hope to do buisness with you in the future. Please review the export costs in the statistics section at the end of the article. Avalible is single unit export, limited production export, where you buy the right to build the vehicle in a specific limit based on a lower cost, and full domestic production rights. Full DPRs are more epensive then limited, and are restricted on a case by case basis. We would also like you to review the PIV-28 Heavy Infantry Combat Vehicle, which is also avalible.
Concept:
The MCA-7G model came into existance after practical application of the MCA-7B in combat both on the northern border and aborad. Lessons learned from the B, as well as other tanks in the Sumerian inventory, quickly culmulated with new technological advancements avalible for general use. The MCA-7G was thusly born out of the idea that although the MCA-7B was highly capable and exceptional in it's abilities, it was not at the full potential of the design, and so the G model upgrade project was begun.
Shortly after the release of the MCA-7B to general use within the Igimekalam number of vehicles were set aside specificly for testing new and potential future upgrades. Nineveh Armour Works, the primary contractor for the MCA-7 series, began to redesign aspects of the main armament and drive train for test purposes. Testing proved the design path to be quite strong, with many of the new test systems proving, to a degree, superior to those installed already on the B model.
And so, with combat experiance providing the nessesary information, a program to update the MCA-7Bs was put forth before the Office of the Dictator. After several months of rehashing the program's goals with the Office, the final program was approved for development and brought before the Civil Senate for funding. Several weeks later, and the rewriting of the program to include the approval of systems slated for the MCA-7B upgrade to be used in the MCA-7D and other armoured vehicles, the project was approved for funding and allocated the nessecary funds. The update program, designated as the MCA-7G, was concieved around primarily updating the internal systems of the MCA-7, with a new fire control, battlefield managment system, sensors, and other systems. Additionally the entire drivetrain was redesigned to better suit the vehicles needs and capabilities, as well as new armament and an upgrade to the protection scheme.
Although externally identical to the MCA-7B, the G model holds a signifigant number of improvements that make it a clearly superior vehicle. With primary emphisis on a vehicle to combat other armoured formations in the vast open plains of Sumer, the G model contains a carefully calculated balance of firepower, mobility, and protection, with no detriment to its primary mission.
Armament:
The MCA-7G uses a brand new gun derived from the Type-3655 115L62 smoothbore of the prototypes. The new gun, the Type-3700 140L50 is a 140mm weapon scaled up from the older Type-3655 design. The new gun allows higher muzzle velocities, as well as larger projectiles and gun launched anti-tank guided missiles. The Type 998-X16B autoloader system has been also upgraded to Type 998-X16C standards to keep up with the main gun.

The new Type-3700 smoothbore main gun installed in the G model is a larger version of the Type-3650 installed in the B model and Type-3655 installed on the G model prototypes, as previously stated. The new gun is designed to maximize space within the combustion chamber for propellant while allowing a slightly longer barrel for greater expansion of the higher power rounds. The mantle and gun mount had to be redesigned to accommodate the new systems, and a heavier recoil absorption system had to be designed as well, however the reduced recoil length offered by the new mount allowed for the breech of the weapon to be set farther back in the turret then previously possible, allowing greater balance of the main gun and a limiting of the affects of such a long barrel. The 7m long barrel itself has been redesigned using much more compatible materials for construction and duration, allowing for a much stronger barrel then previous. That, coupled with the mounting farther back, has allowed the G model to retain it's high degree of accuracy while on the move, as well as avoid common problems associated with such long barrels. The Type-3700 gun is fired by a brand new electro-thermal ignition system making use of electrically generated radiation to more efficiently ignite and burn the propellant, providing an increase in energy transfer to the projectile. The Type-3700 gun provides a drastic increase in firing energy over the previous 115mm generation of tank guns, allowing greater kill ranges and greater armour penetration at normal combat ranges.
The Type-3700 main gun is fed by a two-stage Type 998-X16C autoloader. The autoloader consists of two separate storage systems for propellant and projectile, allowing maximum safety while the use of more compact two-piece ammunition allows a reduction in space concerns both during storage and after firing the round. The first stage of the autoloader is the carousel ring inside the hull below the turret ring which stores thirty-five An-1100 series 140mm projectiles in an upright position within individual protected container along the primary carousel ring. An additional five rounds are carried along an inset to the carousel system at the forward part of the tank which can be automatically cycled into the main carousel line by the computer. A round is loaded into the main gun by way of an articulated lift arm at the back of the turret which lifts the round from it's container and rotates it ninety degrees to be level with the gun breech. To load a ram arm in the bustle of the turret forces the round and propellant charge into the gun, with the lifting arm acting as a bridge. Propellant stages are kept in the turret bustle behind an armoured bulkhead and access door. The charges are kept within individual armoured containers along a chain-style autoloader system. The bustle holds forty propellant charges which work with all An-1100 series ammunition. The system is fully electric in operation, and manual backups are provided to cycle the charge and projectile racks for manual loading if necessary. Blow out panels are provided for the bustle storage system. The entire system provides rapid fire capability for the tank, allowing cycle times averaging five seconds. Rapid cycle capabilities of the autoloader system far outweigh its inherent complexity, allowing the MCA-7G to unload it's entire forty round capacity in three and a half minutes, an unheard of rate of fire for a main battle tank. Such rate of fire however would quickly wear out the barrel, and is only used for burst fire of three or four rounds in combat.
The G model retains the 15mm AGH-32 heavy machine gun mounted coaxially to the main gun. The AGH-32 is a dual linkless feed machine gun firing standard 15x120mm caseless ammunition. The AGH-32 is mounted to the left side of the main gun, in front of the gunner's station, and is recessed into the thick mantle with a ventilation port built into the side of the mantle near the barrel. The coaxial gun is fed by two five hundred round drum magazines located under the gunner's reclined position, with either drum able to be selected as the primary feed drum, or both may be selected to mix ammunition types as needed.
A remote weapon station is installed just to the rear of the commander's cupola and slaved to the commander's independent thermal/optical sight. The RWS mount includes a box launcher for two 70mm class heat seeking light anti-aircraft missiles which can be targeted using the commander's independent thermal viewer. The box launcher may be removed as necessary, and can be quickly reloaded by pre-packaged 70mm tubes. The 7.5mm medium machine gun which the RWS mounts standard is derived from the AGS-5 light machine gun with a heavier barrel and is fed by a linkless belt feed drum situated vertically behind the tank commander in the turret.
The MCA-7G additionally comes with a 50mm light adjustable velocity automatic mortar mounted in the rear of the turret bustle. The mortar is fed from two twelve round linkless chutes, allowing a maximum of twenty-four bombs to be carried. The mortar is designed to provide adequate anti-infantry capability at close ranges, with it's ability to angle as high as 90 degrees, as well at standoff ranges out to 3000m when the main gun would not be practical. The system is capable of firing illumination flare rounds and smoke bombs, but is most commonly loaded exclusively with high explosive fragmentation.
Protection:
The armour scheme of the MCA-7G is almost identical to the previous B model, with the exception of more effecient primary bricks designed for the armour. The armour is designed modular around a three layer design. The only signifigant change to the basic armour pattern is the redesign of the interior "hard blocks" which make up the majority of the protection. Each block is, in essence, a titanium shell lined internally and externally with reenforcing high performance polyethylene to provide structural strength even under extreme stress. The interior of the block is filled with a ceramic-metalic material laced with tiny glass fibers for strength and added aggregation as needed. The ceramic-metalic material, developed in secret by Nineveh Armour Works, provides excellent deformation of explosively formed penetrators and other shaped charges, especially in conjunction of the other layers of the armour's system. Additionally, each block contains a pair of crescent shaped depleted uranium bars running lengthwise, suspended within the ceramic-metallic material and coated with copper. The depleted uranium bars are designed to provide complete and overlapping cover of the front and forward cars of protection at all normal strike angles in regular combat. Blocks designed for use in the rear and rear-sides of then turret, as well as the rear half of the vehicle however do not have the depleted uranium inserts.

Pictured: Diagram of the basic structure and workings of Shukur ERA.
Additionally, the G is designed to be equiped with Shukur, or "Lance" explosive reactive armour. The Shukur ERA design works by including a series of small, simple, shaped charge warheads aranged at an angle upwards of the ground but offset from the slope of the base armour by some degrees, depending on the slope of the armour. The system incorporates ignition plates offset to the shaped charge modoules such that a line drawn directly from the middle of the chaped charge heading out would line up through the middle of the ingition plates. The system is designed such that when a penetrating threat penetrates the external ignition plate and makes contact with the internal one it sets off the coresponding chaped charge. The resulting deatonation propelles a molten metal jet, as formed by the shaped charge, towards the threat object, either destroying it or severely disrupting it. The Shukur system is compact, light weight, and safe for nearby unarmoured vehicles and personell, and is avalible in a wide range forms for various parts of the G chassis. Additionally, the Shukur system is capable of excellent protection against both chemical energy threats in the form of High Explosive Anti-Tank, or kinetic energy threats such as long rod penetrators. The Shukur ERA system adds, depending on where it is placed and the angle it is placed at, between six hundred and eight hundred milimeters worth of additional RHA equivilant protection. Unfortunately, due to the nature of the design, the Shukur modoules can not be placed on every surface of the tank, and are often situated around the front and side of both the hull and turret. Top mounted Shukur modoules are avalible for the turret roof od the G model however, but they only provide protection directly over the crew compartment.
The Enlil APS was also updated to Type-2 standards, with new detection systems and soft kill systems added. Amongst the many improvements and additions to the Enlil system was the addition of two pulsed IR lights mounted on the mantlet that assist in the disruption of first and second generation anti tank guided missiles, as well as make the entire vehicle somewhat harder to distinguish through some sensors from the right angle. Further the Type-2 added a two-stage laser soft kill system designed to track and then disrupt enemy optical systems. Finally the hard kill componant of the Enlil was upgraded, with the detection, processing, and execution systems all getting a major upgrade to their capabilities, allowing the Enlil APS to engage incomming shaped charge warheads in the form of both missiles and tank fired rounds, as well as engage tank fired kinetic energy rounds.
The grenade dispensation system of the MCA-7 was replaced with an aerosol dispersion system. The areosol dispersion system can cover the forward arc of the vehicle in an aerosol formed screen, limiting the effeciveness of both laser sighting, regular and IR imaging systems. The aerosol system is controled manually by the commander, and has enough shots to completely disguise the tank seven times. The downside to the new aerosol system is that it also blocks the gunner's ability to fire back on an enemy vehicle, however the use of the milimeter wave radar system within the fire control system reduces this limitation somewhat.
Although not entirely for measure of protection, structural aspects of the hull of the MCA-7G were redesigned, or created anew, to provide a much stronger chassis. Strong reenforcing aspects of the chassis along the front of the hull and fenders, as well as along the rear of the hull and fenders, allow the vehicle to put great strain on the chassis if needed, and protect against impacts from objects such as trees. The reenforcements were designed to allow one G model vehicle to push another free if stuck, or to otherwise assist another damaged tank. Additionally the reenforcements have found use in removing objects from the vehicle's path, including concrete anti-vehicle barriers, telephone and light poles, and trees.
Systems:
Internally the MCA-7G is almost a completely new vehicle. a completely new fiber-optic based fire control system has been designed and installed, named the Gagsisa Type 1, the new system provides extraordinary computing capabilities and speeds for a package better suited to the internals of the vehicle. The Gagsisa system includes a digital all weather day/night sighting device for the gunner which may be accessed and operated from the commander's station, as well as a backup optical sight. Input systems include a manual input interface for both the gunner and commander if nessecary, as well as automatic environmental sensors, a two-mode laser range finder, and a new milimeter wave radar system. The two-mode laser range finder can be operated in a pulsed mode or in a constant stream and is capable of being used to paint an enemy target to assist guided missile variants of the An-1100 series tank rounds. The milimeter wave radar system is slaved to the fire control system and is designed for operation in situations where the laser range finder and stadard detection gear will not work. The milimeter wave radar system, although short ranged out to a maximum of three kilometers under ideal conditions, is capable of cutting through IR and laser disrupting smoke and aerosol screens with ease. Further, a small milimeter wave radar system was installed within the lower front hull to provide the driver control system with time-ahead information regarding the terrain, allowing the new suspension to be adjusted automatically by the computer for maximum stability at speed over terrain. A prototype MCA-7B retrofitted with the new system for testing was able to land all shots fired on a remotely opperated target vehicle from two kilometers using An-1000B kinetic energy rounds while moving at top cross country speed.
The crew is equipped with a full array of digital systems, including key backups, in a user freindly environment. Individual air conditioning is provided within the sealed vehicle, allowing comfortable opperation even under NBC conditions. An overpressure NBC system and air filtration system are standard. Additionally each crewmember is provided with an adjustable seat, angled within the vehicle depending on the crewmember it is placed for. The driver's seat is reclined, with an adjustable angle to allow the driver to sit up comfortable while driving with the hatch open. The gunner's seat is permenantly reclined, with comfort-specific adjustments avalible to the gunner, allowing maximum stability and comfort within the vehicle, as well as nessecary room to stretch, despite the cramped quarters. The commander's seat may be raised or lowered both manually and through an electric actuator system to allow the commander to raise or lowe his seat and view from outside the hatch as needed, or recline his seat as needed. All three crew seats are provided with storage spaces for personal items and canteens. Each crewmember is additionally provided with a hot and cold water outlet from the vehicles internal tank, allowing abundant ammounts of drinking water for mandatory consumption or for drinks like tea.
The driver is provided with a completely digital touch-screen engine managment suit, alongside the standard controls. From here the driver can view and to a small extent manage the engine, drivetrain, and fuel vitals. The driver can additionally shift the balance of fuel in the vehicle's tanks if needed, or pump fuel to another vehicle if connected to do such. The driver has a yolk style driving column with hands-on control layout for the automatic transmission and other small items such as lights and turn signals. The driver has three electro-optical periscopes feeding into three adjustable screens providing day and night viewing capability, as well as a rear-mounted electro-optical camera which can be viewed within one of the primary screens if nessecary. The periscope complex, as with the other periscopes, can be switched from electro-optical to the backup standard optical periscope simple by folding the small screen up and away.
The gunner is provided with a trio of adaptable touch-screens for managment of ammunition and the fire control system. The gunner's digital sight allows all weather operation, and may be switched between day and night modes, as well as set to display information from the much less capable milimeter wave rangefinding and targeting system. This allows the gunner to, in times of extremely low visibility which even standard IR and laser systems can not operate, fire upon enemy tanks. While not as accurate or capable as the standard system, the use of the milimeter wave radar system for targeting allows the crew slight advantage in ultra-low visibility situations. The gunner's control column includes a toggle to switch the FCS between operating the main gun, the coaxial machine gun, and the light mortar, with the system automaticly adjusting to the ballistic qualities of the differing weapons systems in relation to the ammunition chosen and the outside environment. Ammunition os selected via one of the three touch-screens.
The commander is provided with a two-tier visual suit for enhanced capability. Eleven digital screens surrounding the driver provide panoramic day and night views from sixteen well protected external electro-optical periscopes. Like the driver's periscopes, if nessecary the digital aspect of the system can be bypassed and the gunner and commander can make use of the sixteen periscopes as standard. Additionally the commander has a touch-screen display for the battlefield command and control system and controls for varios other duties, many of which can be displayed on the viewing pannels.Additionally the commander's hatch has a built in rotating system including six small standard periscopes, and the commanders independent viewing system for both day and night use. The commander needs only to twist this rotating element and designate a target for the gunner with his independent sight, allowing true hunter-killer capability. The design of the external hatch as well accomodates limited viewing through a slightly raised hatch without the need to fully open the hatch.
The combined electro-optical periscopes provide superior visual capability to the tank crew and especially the commander, while not compromising the nessecary standard periscope systems. The system consists of a standard laser-protected armour periscope with an additional level of a wide-angle high definition digital camera feeding an internal viewing system, allowing excellent under-armour viewing capability at day and night.
Mobility:
The most drastic structural change to the vehicle would be in the form of a complete overhaul of the suspension design, replacing the older eighteen roadwheel assemblies with twenty four interleaved roadwheel assemblies, provided with twelve torsion bars per side. The internals of the new suspension system were almost identical to those of the baseline B series, with the exception of more torsion bars and the replacement of the older hydraulic actuators with smaller and more powerful electrical ones. The new suspension system allows a lower ground pressure, essential for such a heavy tank, as well as allowing the vehicle to take advantage of terrain forms, and manipulate it's own mobility as needed. The adjustable suspension height allows the vehicle to lay almost flat against the ground, providing more sirface area on softer terrain by use of the belly of the hull itself, allowing the MCA-7G to be used in desert areas with somewhat softer sands then most armoured vehicles can manage, with somewhat reduced mobility. Additionally the suspension can be adjusted to take advantage of landforms to create hull down positions, or to allow the main gun to be lowered or raised a little bit extra.
The MCA-7G is powered by a modular mobility pack installed in the rear of the vehicle. The mobility pack includes the engine and limited fuel and water systems, as well as the hydraulic transmission and all protected lines. The system allows rapid change of the engine and transmission in as little as twenty minutes with the assistance of a crane, and also allows the high-pressure hydraulic transmission system to be isolated from the rest of the vehicle for safety reasons. The chassis is designed to accecpt the modular mobility pack and hold it securely in place, providing all connections in easily accessable areas behind the turret and under the turret bustle area.
The Guarita DO86-2T00 engine installed in the G is an upgrade of the former DO86-2S99 engine fitted to the B. The DO86-2T00 is a revolutionary advance in the standard engine, keeping the stadard engine block system of the DO86-2S99 and most of the internals. The primary difference comes from the new higher-flow and strength air intake system combined with a brand new variable turbocharger system. The new turbochargers are designed to provide high pressure through the high flow intercoolers of approxemetly 10 bar, allowing the engine to take full advantage of it's strong high pressure internals. The ability to run turbochargers as opposed to the superchargers needed previously has come about as a result of combining the previous gas turbine UAAPU with the engine system itself. While still providing the duties of the AUAPU, the new gas turbine is designed to provide the turbine pressure direct to the turbochargers of the engine, providing a constant flow of high pressure air into the engine and eliminating the need for the hot start capability of the B. This allows higher power to be acheived, and exceptionally higher torque, while maintaining the engine's other qualities. The gas turbine does not eat any more fuel as it is simply a redesign using the original system. Still retaining the Crower six cycle design and the water reclamation in the redesigned exhaust systems allowing the engine to recycle the water it uses to keep internally cool. The power requierments for the engine were enormus for a number of reasons, including the ability to power all systems in the vehicle. With the multitude of electrical systems within the vehicle, from electric actuatated adjusted suspension to the digital displays for the crew and the entire FCS including the gun itself, the MCA-7G is a power hungry beast. Additionally, the hydraulic transmission system aids in mobility, crucial to such a heavy vehicle. The transmission runs off solid-line hydraulic pressure lines with pressure provided directly by the engine. This allows the engine to run at optimal operating speeds constantly while providing maximum power and torque as needed, drasticaly increasing fuel effeciency overall. The system allows high average ammounts of power and torque to the tracks, allowing the heavy G to be exceptionally mobile. The transmission as well can, if needed, transfer power into torque if nessecary, allowing the G series to act as a buddy recovery vehicle by pushing other tanks out of areas they may have become stuck. The extra torque, which is automaticly controled by the drivetrain managment sensor which adjusts the transmission as needed, also allows the G to force it's way through more solid obstacles such as trees or anti-vehicle concrete barriers if nessecary, but with strain to both the chassis of the vehicle and the drivetrain.
The gas turbine auxilliary under armour power unit has been kept from the B model, allowing hot start capability with the engine. Other upgrades more easily noticed on the new MCA-7G include the installment of a built in dozer blade under the front hull to facilitate self digging of entrenched postsions. Coupled with the advanced adjustable suspension, this device will allow the quick preparation of defensive postsions in the event the MCA-7G should need to. Additionally the external fuel and water tank system was redesigned, with a close fitting water tank installed to the rear of the vehicle and able to be easily removed. A pair of larger, three hundred liter capacity, fuel drums have been hung from the external water tank on quick release system, allowing greater range then the older system, while still providing the safety of being dropped when nessecary. Finally an improved cooling system, tied to the fire control system's environmental sensors, was installed, allowing the vehicle to better control both the engine exhaust temerature and vehicle temperature in regards to the surrounding area. Coupled with the use of more modern heat release dispersion and semi radar absorbant camofualge netting the MCA-7G is set to be one of the hardest to detect armoured vehicles around under limited visibility conditions such as those seen at night, within sand storms or blizards, or within fog.

Export Policy:
Recent export permission has been given to Nineveh Armoured Works to supply an export version of the latest MCA-7 series tank, the G, to foreign interests. The MCA-7E, as it is known, is a fully capable MCA-7G, unlike the previous B-to-C modifications for export. No reductions in protection or capability were made to achieve the E, and only a limited number of modifications were made to the vehicle for export. The following writeup is for the MCA-7G, however the E model is completely identical in all aspects except for the following:
- The MCA-7E package does not include the An-1100H round for export.
- The MCA-7E computer systems have all been built with blank software around the standard systems. This means that the FCS or other systems can be configured to foreign languages and needs, while retaining all capabilities except one.
- The MCA-7E is unable to synchronize with the Sumerian Battle Network because of the previously mentioned computer construction, and safeguards in place. It can easily, however, be configured to work with local BattleNets.
The following ammunition is avalible for export under the conditions specified:
- An-1100A: Production rights come with vehicle purchase.
- An-1100B: Production rights come with vehicle purchase.
- An-1100C: Production rights come with vehicle purchase.
- An-1100D: Production rights come with vehicle purchase.
- An-1100E: Production rights come with vehicle purchase.
- An-1100F: Production rights come with vehicle purchase.
- An-1100G: Avalible for $32,000 USD per missile. ($1.6 billion DPR)
- An-1100H: Not Avalible for Export.
Spare parts production rights are avalible. It should be noted that all technology and equipment design integrated within the MCA-7E is property of the Sumerian government and is thusly copywritten. Any attempt to produce, in whole or in part, the MCA-7E or any of it's componants for export will be reciprocated with actions as deemed fit, up to and including military action.
Further, we wish to issue the following disclaimer: Nineveh Armoured Works, nor the Sumerian government or any of the subcontractors involved in the MCA-7 program can be held responsible for the quality of work by foreign producers under domestic production rights. While we strive to aid foreign industry to the quality demanded by the MCA-7, we hold no responsability in their construction.
We thank you for reviewing the MCA-7E, and hope to do buisness with you in the future. Please review the export costs in the statistics section at the end of the article. Avalible is single unit export, limited production export, where you buy the right to build the vehicle in a specific limit based on a lower cost, and full domestic production rights. Full DPRs are more epensive then limited, and are restricted on a case by case basis. We would also like you to review the PIV-28 Heavy Infantry Combat Vehicle, which is also avalible.
Concept:
The MCA-7G model came into existance after practical application of the MCA-7B in combat both on the northern border and aborad. Lessons learned from the B, as well as other tanks in the Sumerian inventory, quickly culmulated with new technological advancements avalible for general use. The MCA-7G was thusly born out of the idea that although the MCA-7B was highly capable and exceptional in it's abilities, it was not at the full potential of the design, and so the G model upgrade project was begun.
Shortly after the release of the MCA-7B to general use within the Igimekalam number of vehicles were set aside specificly for testing new and potential future upgrades. Nineveh Armour Works, the primary contractor for the MCA-7 series, began to redesign aspects of the main armament and drive train for test purposes. Testing proved the design path to be quite strong, with many of the new test systems proving, to a degree, superior to those installed already on the B model.
And so, with combat experiance providing the nessesary information, a program to update the MCA-7Bs was put forth before the Office of the Dictator. After several months of rehashing the program's goals with the Office, the final program was approved for development and brought before the Civil Senate for funding. Several weeks later, and the rewriting of the program to include the approval of systems slated for the MCA-7B upgrade to be used in the MCA-7D and other armoured vehicles, the project was approved for funding and allocated the nessecary funds. The update program, designated as the MCA-7G, was concieved around primarily updating the internal systems of the MCA-7, with a new fire control, battlefield managment system, sensors, and other systems. Additionally the entire drivetrain was redesigned to better suit the vehicles needs and capabilities, as well as new armament and an upgrade to the protection scheme.
Although externally identical to the MCA-7B, the G model holds a signifigant number of improvements that make it a clearly superior vehicle. With primary emphisis on a vehicle to combat other armoured formations in the vast open plains of Sumer, the G model contains a carefully calculated balance of firepower, mobility, and protection, with no detriment to its primary mission.
Armament:
The MCA-7G uses a brand new gun derived from the Type-3655 115L62 smoothbore of the prototypes. The new gun, the Type-3700 140L50 is a 140mm weapon scaled up from the older Type-3655 design. The new gun allows higher muzzle velocities, as well as larger projectiles and gun launched anti-tank guided missiles. The Type 998-X16B autoloader system has been also upgraded to Type 998-X16C standards to keep up with the main gun.

Pictured: An unarmoured MCA-7 series turret mounted on an MCA-5 as a testbed for the Type-3700 smoothbore gun. Taken durring live fire exercises at Nas-Arabeh Proving Grounds.
The new Type-3700 smoothbore main gun installed in the G model is a larger version of the Type-3650 installed in the B model and Type-3655 installed on the G model prototypes, as previously stated. The new gun is designed to maximize space within the combustion chamber for propellant while allowing a slightly longer barrel for greater expansion of the higher power rounds. The mantle and gun mount had to be redesigned to accommodate the new systems, and a heavier recoil absorption system had to be designed as well, however the reduced recoil length offered by the new mount allowed for the breech of the weapon to be set farther back in the turret then previously possible, allowing greater balance of the main gun and a limiting of the affects of such a long barrel. The 7m long barrel itself has been redesigned using much more compatible materials for construction and duration, allowing for a much stronger barrel then previous. That, coupled with the mounting farther back, has allowed the G model to retain it's high degree of accuracy while on the move, as well as avoid common problems associated with such long barrels. The Type-3700 gun is fired by a brand new electro-thermal ignition system making use of electrically generated radiation to more efficiently ignite and burn the propellant, providing an increase in energy transfer to the projectile. The Type-3700 gun provides a drastic increase in firing energy over the previous 115mm generation of tank guns, allowing greater kill ranges and greater armour penetration at normal combat ranges.
The Type-3700 main gun is fed by a two-stage Type 998-X16C autoloader. The autoloader consists of two separate storage systems for propellant and projectile, allowing maximum safety while the use of more compact two-piece ammunition allows a reduction in space concerns both during storage and after firing the round. The first stage of the autoloader is the carousel ring inside the hull below the turret ring which stores thirty-five An-1100 series 140mm projectiles in an upright position within individual protected container along the primary carousel ring. An additional five rounds are carried along an inset to the carousel system at the forward part of the tank which can be automatically cycled into the main carousel line by the computer. A round is loaded into the main gun by way of an articulated lift arm at the back of the turret which lifts the round from it's container and rotates it ninety degrees to be level with the gun breech. To load a ram arm in the bustle of the turret forces the round and propellant charge into the gun, with the lifting arm acting as a bridge. Propellant stages are kept in the turret bustle behind an armoured bulkhead and access door. The charges are kept within individual armoured containers along a chain-style autoloader system. The bustle holds forty propellant charges which work with all An-1100 series ammunition. The system is fully electric in operation, and manual backups are provided to cycle the charge and projectile racks for manual loading if necessary. Blow out panels are provided for the bustle storage system. The entire system provides rapid fire capability for the tank, allowing cycle times averaging five seconds. Rapid cycle capabilities of the autoloader system far outweigh its inherent complexity, allowing the MCA-7G to unload it's entire forty round capacity in three and a half minutes, an unheard of rate of fire for a main battle tank. Such rate of fire however would quickly wear out the barrel, and is only used for burst fire of three or four rounds in combat.
The G model retains the 15mm AGH-32 heavy machine gun mounted coaxially to the main gun. The AGH-32 is a dual linkless feed machine gun firing standard 15x120mm caseless ammunition. The AGH-32 is mounted to the left side of the main gun, in front of the gunner's station, and is recessed into the thick mantle with a ventilation port built into the side of the mantle near the barrel. The coaxial gun is fed by two five hundred round drum magazines located under the gunner's reclined position, with either drum able to be selected as the primary feed drum, or both may be selected to mix ammunition types as needed.
A remote weapon station is installed just to the rear of the commander's cupola and slaved to the commander's independent thermal/optical sight. The RWS mount includes a box launcher for two 70mm class heat seeking light anti-aircraft missiles which can be targeted using the commander's independent thermal viewer. The box launcher may be removed as necessary, and can be quickly reloaded by pre-packaged 70mm tubes. The 7.5mm medium machine gun which the RWS mounts standard is derived from the AGS-5 light machine gun with a heavier barrel and is fed by a linkless belt feed drum situated vertically behind the tank commander in the turret.
The MCA-7G additionally comes with a 50mm light adjustable velocity automatic mortar mounted in the rear of the turret bustle. The mortar is fed from two twelve round linkless chutes, allowing a maximum of twenty-four bombs to be carried. The mortar is designed to provide adequate anti-infantry capability at close ranges, with it's ability to angle as high as 90 degrees, as well at standoff ranges out to 3000m when the main gun would not be practical. The system is capable of firing illumination flare rounds and smoke bombs, but is most commonly loaded exclusively with high explosive fragmentation.
Protection:
The armour scheme of the MCA-7G is almost identical to the previous B model, with the exception of more effecient primary bricks designed for the armour. The armour is designed modular around a three layer design. The only signifigant change to the basic armour pattern is the redesign of the interior "hard blocks" which make up the majority of the protection. Each block is, in essence, a titanium shell lined internally and externally with reenforcing high performance polyethylene to provide structural strength even under extreme stress. The interior of the block is filled with a ceramic-metalic material laced with tiny glass fibers for strength and added aggregation as needed. The ceramic-metalic material, developed in secret by Nineveh Armour Works, provides excellent deformation of explosively formed penetrators and other shaped charges, especially in conjunction of the other layers of the armour's system. Additionally, each block contains a pair of crescent shaped depleted uranium bars running lengthwise, suspended within the ceramic-metallic material and coated with copper. The depleted uranium bars are designed to provide complete and overlapping cover of the front and forward cars of protection at all normal strike angles in regular combat. Blocks designed for use in the rear and rear-sides of then turret, as well as the rear half of the vehicle however do not have the depleted uranium inserts.

Pictured: Diagram of the basic structure and workings of Shukur ERA.
Additionally, the G is designed to be equiped with Shukur, or "Lance" explosive reactive armour. The Shukur ERA design works by including a series of small, simple, shaped charge warheads aranged at an angle upwards of the ground but offset from the slope of the base armour by some degrees, depending on the slope of the armour. The system incorporates ignition plates offset to the shaped charge modoules such that a line drawn directly from the middle of the chaped charge heading out would line up through the middle of the ingition plates. The system is designed such that when a penetrating threat penetrates the external ignition plate and makes contact with the internal one it sets off the coresponding chaped charge. The resulting deatonation propelles a molten metal jet, as formed by the shaped charge, towards the threat object, either destroying it or severely disrupting it. The Shukur system is compact, light weight, and safe for nearby unarmoured vehicles and personell, and is avalible in a wide range forms for various parts of the G chassis. Additionally, the Shukur system is capable of excellent protection against both chemical energy threats in the form of High Explosive Anti-Tank, or kinetic energy threats such as long rod penetrators. The Shukur ERA system adds, depending on where it is placed and the angle it is placed at, between six hundred and eight hundred milimeters worth of additional RHA equivilant protection. Unfortunately, due to the nature of the design, the Shukur modoules can not be placed on every surface of the tank, and are often situated around the front and side of both the hull and turret. Top mounted Shukur modoules are avalible for the turret roof od the G model however, but they only provide protection directly over the crew compartment.
The Enlil APS was also updated to Type-2 standards, with new detection systems and soft kill systems added. Amongst the many improvements and additions to the Enlil system was the addition of two pulsed IR lights mounted on the mantlet that assist in the disruption of first and second generation anti tank guided missiles, as well as make the entire vehicle somewhat harder to distinguish through some sensors from the right angle. Further the Type-2 added a two-stage laser soft kill system designed to track and then disrupt enemy optical systems. Finally the hard kill componant of the Enlil was upgraded, with the detection, processing, and execution systems all getting a major upgrade to their capabilities, allowing the Enlil APS to engage incomming shaped charge warheads in the form of both missiles and tank fired rounds, as well as engage tank fired kinetic energy rounds.
The grenade dispensation system of the MCA-7 was replaced with an aerosol dispersion system. The areosol dispersion system can cover the forward arc of the vehicle in an aerosol formed screen, limiting the effeciveness of both laser sighting, regular and IR imaging systems. The aerosol system is controled manually by the commander, and has enough shots to completely disguise the tank seven times. The downside to the new aerosol system is that it also blocks the gunner's ability to fire back on an enemy vehicle, however the use of the milimeter wave radar system within the fire control system reduces this limitation somewhat.
Although not entirely for measure of protection, structural aspects of the hull of the MCA-7G were redesigned, or created anew, to provide a much stronger chassis. Strong reenforcing aspects of the chassis along the front of the hull and fenders, as well as along the rear of the hull and fenders, allow the vehicle to put great strain on the chassis if needed, and protect against impacts from objects such as trees. The reenforcements were designed to allow one G model vehicle to push another free if stuck, or to otherwise assist another damaged tank. Additionally the reenforcements have found use in removing objects from the vehicle's path, including concrete anti-vehicle barriers, telephone and light poles, and trees.
Systems:
Internally the MCA-7G is almost a completely new vehicle. a completely new fiber-optic based fire control system has been designed and installed, named the Gagsisa Type 1, the new system provides extraordinary computing capabilities and speeds for a package better suited to the internals of the vehicle. The Gagsisa system includes a digital all weather day/night sighting device for the gunner which may be accessed and operated from the commander's station, as well as a backup optical sight. Input systems include a manual input interface for both the gunner and commander if nessecary, as well as automatic environmental sensors, a two-mode laser range finder, and a new milimeter wave radar system. The two-mode laser range finder can be operated in a pulsed mode or in a constant stream and is capable of being used to paint an enemy target to assist guided missile variants of the An-1100 series tank rounds. The milimeter wave radar system is slaved to the fire control system and is designed for operation in situations where the laser range finder and stadard detection gear will not work. The milimeter wave radar system, although short ranged out to a maximum of three kilometers under ideal conditions, is capable of cutting through IR and laser disrupting smoke and aerosol screens with ease. Further, a small milimeter wave radar system was installed within the lower front hull to provide the driver control system with time-ahead information regarding the terrain, allowing the new suspension to be adjusted automatically by the computer for maximum stability at speed over terrain. A prototype MCA-7B retrofitted with the new system for testing was able to land all shots fired on a remotely opperated target vehicle from two kilometers using An-1000B kinetic energy rounds while moving at top cross country speed.
The crew is equipped with a full array of digital systems, including key backups, in a user freindly environment. Individual air conditioning is provided within the sealed vehicle, allowing comfortable opperation even under NBC conditions. An overpressure NBC system and air filtration system are standard. Additionally each crewmember is provided with an adjustable seat, angled within the vehicle depending on the crewmember it is placed for. The driver's seat is reclined, with an adjustable angle to allow the driver to sit up comfortable while driving with the hatch open. The gunner's seat is permenantly reclined, with comfort-specific adjustments avalible to the gunner, allowing maximum stability and comfort within the vehicle, as well as nessecary room to stretch, despite the cramped quarters. The commander's seat may be raised or lowered both manually and through an electric actuator system to allow the commander to raise or lowe his seat and view from outside the hatch as needed, or recline his seat as needed. All three crew seats are provided with storage spaces for personal items and canteens. Each crewmember is additionally provided with a hot and cold water outlet from the vehicles internal tank, allowing abundant ammounts of drinking water for mandatory consumption or for drinks like tea.
The driver is provided with a completely digital touch-screen engine managment suit, alongside the standard controls. From here the driver can view and to a small extent manage the engine, drivetrain, and fuel vitals. The driver can additionally shift the balance of fuel in the vehicle's tanks if needed, or pump fuel to another vehicle if connected to do such. The driver has a yolk style driving column with hands-on control layout for the automatic transmission and other small items such as lights and turn signals. The driver has three electro-optical periscopes feeding into three adjustable screens providing day and night viewing capability, as well as a rear-mounted electro-optical camera which can be viewed within one of the primary screens if nessecary. The periscope complex, as with the other periscopes, can be switched from electro-optical to the backup standard optical periscope simple by folding the small screen up and away.
The gunner is provided with a trio of adaptable touch-screens for managment of ammunition and the fire control system. The gunner's digital sight allows all weather operation, and may be switched between day and night modes, as well as set to display information from the much less capable milimeter wave rangefinding and targeting system. This allows the gunner to, in times of extremely low visibility which even standard IR and laser systems can not operate, fire upon enemy tanks. While not as accurate or capable as the standard system, the use of the milimeter wave radar system for targeting allows the crew slight advantage in ultra-low visibility situations. The gunner's control column includes a toggle to switch the FCS between operating the main gun, the coaxial machine gun, and the light mortar, with the system automaticly adjusting to the ballistic qualities of the differing weapons systems in relation to the ammunition chosen and the outside environment. Ammunition os selected via one of the three touch-screens.
The commander is provided with a two-tier visual suit for enhanced capability. Eleven digital screens surrounding the driver provide panoramic day and night views from sixteen well protected external electro-optical periscopes. Like the driver's periscopes, if nessecary the digital aspect of the system can be bypassed and the gunner and commander can make use of the sixteen periscopes as standard. Additionally the commander has a touch-screen display for the battlefield command and control system and controls for varios other duties, many of which can be displayed on the viewing pannels.Additionally the commander's hatch has a built in rotating system including six small standard periscopes, and the commanders independent viewing system for both day and night use. The commander needs only to twist this rotating element and designate a target for the gunner with his independent sight, allowing true hunter-killer capability. The design of the external hatch as well accomodates limited viewing through a slightly raised hatch without the need to fully open the hatch.
The combined electro-optical periscopes provide superior visual capability to the tank crew and especially the commander, while not compromising the nessecary standard periscope systems. The system consists of a standard laser-protected armour periscope with an additional level of a wide-angle high definition digital camera feeding an internal viewing system, allowing excellent under-armour viewing capability at day and night.
Mobility:
The most drastic structural change to the vehicle would be in the form of a complete overhaul of the suspension design, replacing the older eighteen roadwheel assemblies with twenty four interleaved roadwheel assemblies, provided with twelve torsion bars per side. The internals of the new suspension system were almost identical to those of the baseline B series, with the exception of more torsion bars and the replacement of the older hydraulic actuators with smaller and more powerful electrical ones. The new suspension system allows a lower ground pressure, essential for such a heavy tank, as well as allowing the vehicle to take advantage of terrain forms, and manipulate it's own mobility as needed. The adjustable suspension height allows the vehicle to lay almost flat against the ground, providing more sirface area on softer terrain by use of the belly of the hull itself, allowing the MCA-7G to be used in desert areas with somewhat softer sands then most armoured vehicles can manage, with somewhat reduced mobility. Additionally the suspension can be adjusted to take advantage of landforms to create hull down positions, or to allow the main gun to be lowered or raised a little bit extra.
The MCA-7G is powered by a modular mobility pack installed in the rear of the vehicle. The mobility pack includes the engine and limited fuel and water systems, as well as the hydraulic transmission and all protected lines. The system allows rapid change of the engine and transmission in as little as twenty minutes with the assistance of a crane, and also allows the high-pressure hydraulic transmission system to be isolated from the rest of the vehicle for safety reasons. The chassis is designed to accecpt the modular mobility pack and hold it securely in place, providing all connections in easily accessable areas behind the turret and under the turret bustle area.
The Guarita DO86-2T00 engine installed in the G is an upgrade of the former DO86-2S99 engine fitted to the B. The DO86-2T00 is a revolutionary advance in the standard engine, keeping the stadard engine block system of the DO86-2S99 and most of the internals. The primary difference comes from the new higher-flow and strength air intake system combined with a brand new variable turbocharger system. The new turbochargers are designed to provide high pressure through the high flow intercoolers of approxemetly 10 bar, allowing the engine to take full advantage of it's strong high pressure internals. The ability to run turbochargers as opposed to the superchargers needed previously has come about as a result of combining the previous gas turbine UAAPU with the engine system itself. While still providing the duties of the AUAPU, the new gas turbine is designed to provide the turbine pressure direct to the turbochargers of the engine, providing a constant flow of high pressure air into the engine and eliminating the need for the hot start capability of the B. This allows higher power to be acheived, and exceptionally higher torque, while maintaining the engine's other qualities. The gas turbine does not eat any more fuel as it is simply a redesign using the original system. Still retaining the Crower six cycle design and the water reclamation in the redesigned exhaust systems allowing the engine to recycle the water it uses to keep internally cool. The power requierments for the engine were enormus for a number of reasons, including the ability to power all systems in the vehicle. With the multitude of electrical systems within the vehicle, from electric actuatated adjusted suspension to the digital displays for the crew and the entire FCS including the gun itself, the MCA-7G is a power hungry beast. Additionally, the hydraulic transmission system aids in mobility, crucial to such a heavy vehicle. The transmission runs off solid-line hydraulic pressure lines with pressure provided directly by the engine. This allows the engine to run at optimal operating speeds constantly while providing maximum power and torque as needed, drasticaly increasing fuel effeciency overall. The system allows high average ammounts of power and torque to the tracks, allowing the heavy G to be exceptionally mobile. The transmission as well can, if needed, transfer power into torque if nessecary, allowing the G series to act as a buddy recovery vehicle by pushing other tanks out of areas they may have become stuck. The extra torque, which is automaticly controled by the drivetrain managment sensor which adjusts the transmission as needed, also allows the G to force it's way through more solid obstacles such as trees or anti-vehicle concrete barriers if nessecary, but with strain to both the chassis of the vehicle and the drivetrain.
The gas turbine auxilliary under armour power unit has been kept from the B model, allowing hot start capability with the engine. Other upgrades more easily noticed on the new MCA-7G include the installment of a built in dozer blade under the front hull to facilitate self digging of entrenched postsions. Coupled with the advanced adjustable suspension, this device will allow the quick preparation of defensive postsions in the event the MCA-7G should need to. Additionally the external fuel and water tank system was redesigned, with a close fitting water tank installed to the rear of the vehicle and able to be easily removed. A pair of larger, three hundred liter capacity, fuel drums have been hung from the external water tank on quick release system, allowing greater range then the older system, while still providing the safety of being dropped when nessecary. Finally an improved cooling system, tied to the fire control system's environmental sensors, was installed, allowing the vehicle to better control both the engine exhaust temerature and vehicle temperature in regards to the surrounding area. Coupled with the use of more modern heat release dispersion and semi radar absorbant camofualge netting the MCA-7G is set to be one of the hardest to detect armoured vehicles around under limited visibility conditions such as those seen at night, within sand storms or blizards, or within fog.
