How much of that is armor?
Also, does the hull side stop the reference threats?
I also note that the hull does not stop the BGM-1 from the front.
The exact percentage is currently under review, we haven't worked out the ERA package and side skirts
The hull side in the depicted prototype does not stop several of the reference threats, however we are working on both a HIC side skirt and a LIC one which should provide the required protection
The hull requires ERA to stop BGM-1 from the front, this has not been modeled as the ERA design is still in development.

As a result the round has a very strange trajectory.
How are you ensuring it reliably follows the same trajectory, and that that trajectory can be calculated with the mechanical/electro-mechanical computers available?
How does the rocket firing inside the bore effect barrel life? Wouldn't that rapidly raise the chamber pressure? If I'm reading right aren't APCP's exhaust is not good to breathe and has a prominent signature, do you have any plans to address this?

Thoughts on the Proper Use of Mechanized Forces in Defense Against the Probably Enemy to the West, Military-Scientific Thought, Summer 2250
Inspired by the current procurement of a new armored vehicle, the author has briefly made a closer study of the terrain on our axes of probable deployment, based in their experience of war in the former Nevada.
The elevations in the Northern Theater of Military Affairs, excepting the Columbia Plateau on the former Oregon-Washington border and the Snake River Basin, tend towards above FL040 and in fact are often above FL050.
In the Eastern Theater of Military Affairs, the terrain is likewise often above FL040 or FL050 throughout northern Former-Arizona, Former-New Mexico, and Former-Utah. Much of the terrain is above FL040, even the valleys between ridgelines in Former-Nevada, where the remnants of pre-war road networks, arid unforested scrub, and relatively flat ground allow the dushman toyota cavalry to utilize their greater tactical mobility. Worse still would be an engagement in one of the open dry lakes which dot these valleys, where their greater on road/salt flat/lakebed speed enables them to decisively outmaneuver nearly any conceivable tracked vehicle, and attack the sides/rear with their powerful anti-tank means.
The peaks which separate these valleys are dominating terrain features, often rising above FL100, however the limited engagement ranges of current fire control systems mean that the ability to observe often the entire >10 mile width of the valley (weather permitting) is hampered by an inability to engage the targets observed, at the least with tank gun fire. An interesting conundrum, no doubt. It is conceivable that the very high caliber guns being pursued by the various parties of this competition may be able to engage such targets, using fire by direct aiming to deliver HE-FRAG, VT, or DPICM against the lightly armored opponents.
On the other hand, this job could be better accomplished by heliborne light infantry with long-ranged ATGM and a light, airmobile SPH of c.4.75" caliber able to fire shells to 10 miles (15 with RAP), and effective aviation support (fixed or rotary wing). The low "footprint" of the light infantry soldier, in comparison to the heavy mechanized unit, would reduce sustainment needs relative to armored forces, and reduce the effectiveness of enemy ISTAR means. A mission-tailored task grouping based off of an airborne infantry regiment could take any point in the whole of the Newark and Diamond valleys to the East and West under fire, and direct air and artillery fires against throughout Eureka, White Pine, and Elko counties. A lower profile force could be used, consisting of a network of observation posts with long-range radio systems to plot enemy movements, and use rotary or fixed wing aviation to "herd" or channelize the zealots into coordinated fire-strikes using high power artillery or the weapons of our illustrious rocket-missile troops.
Indeed, we need a unique kind of vehicle to support this style of warfare. Tentatively termed "4th Dimensional" (three dementions+3D cross domain personeuver) warfare. While past authors have spoken of similar needs for high speed tracked vehicles for this purpose, due to their higher cross country ability and greater protection than wheeled death traps, their suggestions, derived from the pre-war M113 Gavin APC, would be hopelessly outclassed by the toyota cavalry of the mormonhideen. Thus, inspiration should be taken from the pre-war Combat Vehicle (Recconaissance) Tracked series of vehicles. Of particular note are:
FV101 "Scorpion" light tank, so named for the 'sting' of its 76mm gun
FV-107 Scimitar Reconnaissance vehicle, armed with a 30mm cannon and named for the famous sword of the Medieval Arab cavalryman who's descendants perfected the toyota cavalry concept.
FV105 Sultan Command track, allowing the 4th Dimensional personevuer commander to keep pace with their subordinates even in the highest tempo actions
FV102 Striker ATGM carrier, able to sling lethal highly maneuverable missiles from outside enemy gun ranges
FV103 Spartan Armored Personnel Carrier, as light and maneuverable as the light infantry inside, with low ground pressure and good power to weight allowing it to be far more of a 'go anywhere do anything' vehicle than the "jeep" of WWII
However, the modern requirements of today require a new approach, and some new vehicles. The Light Tank would need increased lethality compared to the pre-war 76mm, for example, and a 4.75" howitzer motor carriage would be required. Further additions may include an engineering vehicle, Anti-Aircraft gun motor carriage, and a mortar carrier.
Armed with these new vehicles, light infantry forces would be able to move faster, across, through, and over worse terrain, with heavier weapons, than the mormonhideen. The efforts of the Armored Branch to continue investment in over-complicated expensive vehicles is indicative of the decadence, sedentaryism, and intellectual lethargy which has arisen within the Armored Branch. One might reasonably expect such simple-minded solutions from the robotic money-grubbing degenerates in Cascadia or insane religious fanatics of the tribes who inhabit the Eastern wastes. To see such behavior within the PAF Armored Branch is beyond the pale. Instead of thinking of new ways to skin cats, our fellow officers might best be thinking about how to herd them.

These shell types will allow the AFV-50 to engage and defeat all known and planned enemy combat vehicles should they foolishly decide to attack the peace loving peoples’ republic. They are effective at all combat ranges, allowing the gun tank to decisively deconstruct aggressions, micro and macro, and fulfill its combat tasks.
Secondly for today, the SNVZ collective would like to discuss the early development of our armor schemes. While it is a capital offense to shame for weight, it is important to note that later design iterations have exceeded initial goals. Truly SNVZ and the AFV-50 program have been blessed with the bounty of L Ron Hubbard Thought and it is important to recognize that our vehicle is healthy at any size.
Recognizing the threat posed by CE warheads, the design team initially investigated the use of large volumes of Glass Textolite, alongside steel. (Fig.1) Unfortunately the thicknesses required were rather extreme, and resulted in deep inefficiencies.
Spoiler
Fig.1
To compensate for these deficiencies the ratio of steel to textolite was increased, however this also increased the weight. The integration of layers of ceramic and High-Hardness Steel was investigated, however the density/areal density of these packages was deeply unsatisfactory. (Fig.2)
Spoiler
Fig.2
At this time the collective investigated various arrangements of so called “Special” or “Composite” armor arrays. They were found unappealing due to the large volumes needed to contain them, and the angles required for best performance. (Figs. 3, 4, and 5)
Spoiler
Fig.3
Spoiler
Fig.4
Spoiler
Fig.5
At this time it is unclear what growth potential the Cascadian tandem-HEAT warhead may have, and/or the Mormohideen 2”/4”. These high lethality threat systems may not be able to be defeated without elaborate and economically infeasible exotic armor schemes, in the view of the SNVZ design collective. At this time the SNVZ collective is pursuing further armor concept development, but it appears that the weight and size of tanks must increase drastically before adequate levels of protection are possible. Therefore it appears that the medium tank as it is known, cannot be survivable on the modern battlefield.
The Cascadian introduction and adoption of the <<Norman>> series appears in hindsight to be a drastic misstep. The current service variation (NORMAN-A) appears to utilize conventional steel armor materials in a relatively novel layout. However, this is hopelessly outclassed by modern tandem charge CE technology. The Cascadians appear mindless stooges of chauvinist revanchism and warmongering, however despite their perfidy, they are not stupid. They are likely to be investigating the potential for equipping a derivative of NORMAN-A with exotic “special” or “composite” armor systems. They are fools for doing so! To defeat modern tandem-shaped charges would require far too much volume and weight of armor to fit in a traditional “medium” size tank. But the Cascadian dogs have made their bed, and so they shall sleep in it. They may as well have introduced the kite shields and chainmail of its namesake, for the good it will do them. In the modern threat environment, where tandem charge ATGMs outrange the ability of armor to detect and engage them prior to, or even after, launch, the Medium Tank is dead!
For this reason, the SNVZ AFV-50 designs have blossomed through the iterative process, between 20 and 25% over the initial predictions. Fortunately there is historical precedent for such a matter. Ancient pre-war historical texts speak of a mightily effective Main-Battle Tank, the first of its kind. During the Second Great War it was created, and grew through its design process it grew to just over 1.25x the initial design goal. The Tank Struggle Vehicle Mark 5, or “Panther”, was widely regarded by the ancient sages of the “AxisHistory” forum as the best tank of this second of the great wars, with armor, mobility, and firepower an order of magnitude above the delicate, vulnerable, underarmed and expensive Medium tank M4 "Ronson". Clearly in light of this the weight gain of the AFV-50 is not of much relevance. Collective efforts of SNVZ to improve armor protection continue, and appear to be reaching some success. The DPRC, guardians of the people and L. Ron Hubbard Thought, as well as our most eminent and wise leadership, the most Gracious and Serene Majesty Queen Diane Feinstein the VIII, require cheap winners, like the TSV Mk.5 "Panther" of old, rather than "expensive losers" like the "NORMAN" or "Ronson"! On this matter, I assure you that the shock-engineers of SNVZ will deliver!

Does anyone have information on the composition of Stillbrew? I've been under the impression that it was simply solid steel with a rubber supporting layer bolted to the Chieftain's turret face, however some information I've read alluded to it "sounding hollow" when knocked on?

Four others and I have joined together in the spirit of collective labor to form the SierraNevadaVagonzavod, a collective design bureau. We are currently investigating vehicles under the program designation AFV-50 (Armored Fighting Vehicle 2250).
AFV-50 will be equipped with a powerful smoothbore gun of greater than 100mm bore and over 35 calibers in length. It will be equipped with sufficiently tailored ammunition to auditorily correct the political and moral failings of our northern and western neighbors.
The collective has determined that an automatic loading mechanism will allow all crew personnel to express their individual strengths, political, moral, physical, emotional, spiritual, and otherwise, towards the collective goal most equally. We believe that the performance should far exceed the requirements as posed in the RFP, a feat only achieved through intense study of the works of Comrade Hubbard, Praise be upon them, may their everlasting name be sung eternally from the peoples’ lips, and signed from their hands.
Always on our guard, the Shock-Workers of the SNVZ have designed an armoring scheme which will be equipped to resist all potential and future threats to our peaceful way of existence from all angles. Should the Cascadian Warmongers and their Feudal religious zealot accomplices dare to follow through their bellicose rhetoric, the AFV-50 will be able to resist all aggression, macro and micro, from all current and prospective threat systems. However! The design collective has always taken to heart the words of Comrade Feinstein the 5th:
The greatest weapon in the arsenal of the DPRC is not our guns or bombs, but L Ron Hubbard Thought.
This is the true armor which protects our people and way of life. It is the design collective’s hope that our armor design may in the balance be worthy of utterance in the same sentence as the name of the Great Prophet Hubbard, Praise be upon them, may their everlasting name be sung eternally from the peoples’ lips, and signed from their hands.

Howdy doody folks. I'm not an engineer, but I do do a lot of open source research and I stumbled across something that looks to circumstantially confirm a suspicion I've had for a while.
It all started with an image, Fig. 1. I came across it googling stuff about the AFTI/F-16. Squint reading lead me to believe it was describing how the F-35's flight control systems descend from AFTI/F-16's. But it was stuck behind a paywall. So I did some more digging...
(Fig 1.) source https://arc.aiaa.org/doi/abs/10.2514/6.2018-3368
Lockmart came to the rescue, hosting the document for free, for some reason. https://www.lockheedmartin.com/content/dam/lockheed-martin/eo/documents/webt/F-35_Air_Vehicle_Technology_Overview.pdf
Here's the image in a size you can read:
Now, why is this interesting. After a quick skim it occurred to me that the description was of all the infrastructure to take advantage of a DFCS, excepting the computer inputs. There was no substantial mention of AFTI/F-16's DFCS in the paper, which seemed a little weird because that's what it's known for.
So, this leads me to a circumstantial conclusion: The F-35 is quite possibly either already, or may potentially be capable of functioning with decoupled flight controls. What's that mean? I'll let NASA explain.

@Zyklon some notes: (I was the designer of Mahan's light, he did a chunk of the engineering work and buggered the formatting)
I'm fairly sure I mentioned that the Recoilless Rifles are mainly to provide direct HE / Cannister / APERS fire support, with only a secondary HEAT capability, to offset the lackluster HE performance of the primary armament. While I can't see a technical problem with mounting NLM's or another design of ATGM, I wasn't sure of how to indicate this within the competition. In addition I'm not sure how the practical difference works out between reloading recoilless rifles and ATGMs.@LoooSeR and @Jeeps_Guns_Tanks I'd love to hear your feedback as well, I'm not sure what went wrong, per-se? I realize it's a little naive to expect to win on the first go-round but yeah, onwards and upwards!

Vehicle designer’s notes: As chief designer of the 2250 Heavy Tank program at SNVZ, we had spent quite some time theorizing about ways to remedy the, frankly, superiority of the Cascadian "Norman" Medium Tank over current Californian vehicles. Our design needed to not only meet the Norman, but exceed it, by enough to ensure that no simple upgrades of the Cascadian design could undermine the qualitative advantage our design held. Where the Norman is, in many ways, a radically re-designed and improved T-55, SNVZ decided to take a similar approach with the far superior T-72. The result is a robust, light weight, technologically advanced, and astoundingly lethal vehicle which can be comfortably operated in all environments which it could expect to face, from the heat of the Mojave to the alpine chill of the Sierra Nevadas.

2. Main Weapon- 2A35 (image in spoiler tag)
a. Type: Smooth Bore Tank Gun
b. Caliber: 125mm L/48
c. Ammunition types and performance (short)
Ammunition for 125mm gun 2A35
L-R: 3BK1, 3BK2, 3OF1, 3BM4, 3BM3, 3BM2, 3BR1
(3BM2, 3BM3, and 3BM4 are HVTPTO)
d. Ammo stowage arrangement
The AL-type carousel-pattern automatic loader is capable of handling cartridges of 950mm overall length (technically 975 is the physical limit, but it is believed that a 950mm cartridge overall length limit allows significant room for growth while leaving some clearance inside the autoloader). It services the gun in circa 6 seconds, providing a reliable 10-round-per-minute rate of fire. It is fed by a 30-round carousel, with the cartridges arranged vertically around the turret ring. Reloading the autoloader carousel is conducted by the crew, and most of the shells are a single-person lift. Some of the more exotic types, including but not limited to 3BR1, 3BK2, 3OF1, 3OF3, and 3UBM3 are shipped separately as two pieces, and assembled during loading into the autoloader carousel due to the high projectile weight.
The vehicle is provided with two hull ammunition racks flanking the driver, which are not able to be loaded from in combat and are NOT capable of storing 3BK2, 3OF3, or 3UBM3. The autoloader separates the turret basket from the hull with a steel splinter-protective bulkhead of 5mm thickness and the driver is unable to maneuver those sorts of ammunition through the loading hatch. Total ammunition stowage for the main gun is 45 rounds, 30 in the autoloader and 15 in the hull storage racks.
e. FCS- relevant systems, relevant sights for operating the weapon and so on.
The 7M13 fire control system and its 5E1 Turret/Weapon Management Computer (TWMC) provide gun-follows-sight operation. Bearing information from the sights is combined with the rangefinder setting automatically and continuously by the 5E1 to create ballistics solutions, which are fed forward to the gun laying system. The 7M13 is able to control the 2A35 or the coaxial PKT and the commander’s KPVT simultaneously at a ballistic solution rate of 20Hz. Commander's KPVT can be run with a "Gun-Follows-Sight" logic. Computed ballistic solutions are then transmitted through the gunlaying subsystem, which integrates stabilizer feedback in an analog system and drives the controlled weapons to meet the trajectory demand. The TWMC then implements continuous-consent firing, tracking actual gun position against demanded and firing once aligned. Additionally, the TWMC is responsible for providing guidance commands for the AP-SFRJ projectile based on the SACLOS tracker.
Ballistic solutions take into account ammunition type (acquired automatically from the autoloader), barrel droop and wear (acquired from the muzzle reference sensor and a log of the ammunition fired), turret traverse, vehicle cant, wind speed/direction, as well as external atmospheric pressure, temperature, and humidity. All parameters are acquired automatically by vehicle sensors, avoiding manual input into the system outside of the sights and rangefinder.
Crew interaction with the vehicle automation systems, including the 5E1 and 5E3, takes place through two Crew Display Units (CDUs) provided to the commander and gunner. The CDUs consist of backlit direct-drive TN LCD panels with pre-printed graphical objects and offer both daytime (5W fluorescent backlight) or nighttime (5W incandescent red) illumination. The CDUs display current computer status, gunlaying information, and provide a 64-character text input mode for digital communication and computer control. Interaction is provided through a integrated QUERTY keyboard as well as glove-compatible side buttons.
Each CDU is controlled by a driver IC made on the 100μm node implementing a write-line UART serial communication scheme from the TWMC. User input is fed back to the TWMC over a second serial bus.
f. Neat features. -- See Above
3. Secondary weapons-
Coaxial PKT:
Feeding from left to right with a disintegrating link belt. Mounted in the Mk.18 mount, and provided with 4000 rounds ammunition, of which 2000 is ready. Integrated into the main gun FCS.
Commander's KPVT:
The commander is provided with a 14.5x114mm KPVT heavy machine gun mounted to the cupola, with a sighting and control system for use while under armor. This is provided with 100 rounds of linked ready ammunition, and a further 400 rounds stowed in the turret basket in ammunition cans, with provision made to stow extra ammunition cans to the turret roof for quick reloads. The commander’s KPV can also be used as a manually operated anti-aircraft gun. It was chosen to provide a range overmatch against Mormon forces, as the 14.5x114mm cartridge possesses nearly twice the muzzle energy of the 12.7x99mm round, and has commensurately better long range performance. The Commander’s machine gun is provided with a 1-8x variable power periscopic optical system for use under armor, and back-up iron sights. Control is through electric motors and geared drive, and the gun can be slaved to the sight. It provides light vehicle and anti-infantry capability to 3,000m. The mount is fully stabilized and is able to be used effectively while on the move, and incorporates F50 NGVII image intensifying tubes

B. Optics:
1. Primary gunsight
The TPD-2-49 stereoscopic rangefinding sight assembly is a fully stabilized rangefinder and gunsight with day / night capabilities. Day sighting is provided by two sights, a high field of view periscopic unity sight and a 3 to 12 power variable magnification periscopic sight with illuminated reticle. Night sighting is provided by F50 image intensifying tubes mounted in both the periscopic portion of the sight assembly and in the rangefinder. (F50 is part of the Night Vision Generation II image intensifier program discussed in Appendix 3, Part D: Electro-optical Program Night Vision Generation II.) Provision is made for the replacement or augmentation of the image intensifying system with a thermal imaging system when such a system is ready. The sight is arranged so that replacement of the stereoscopic rangefinder with a laser rangefinder system is possible.
Range information from the TPD-2-49 is automatically transmitted to the 7M13 FCS and is included in the gun-follows-sight control scheme: the ballistic solution is continuously updated by the 5E1 and the gun aimed as the range is dialed in. As a result, firing can take place immediately after the correct range is found.
2.
The commander’s hunter-killer cupola with TDD-3 optical complex is provided with a 1-8x variable power periscopic optical system for use under armor. Control is through electric motors and geared drive, and the 125mm gun can be slaved to the sight (commander's override). In combination with the 14.5mm KPVT machine gun, TDD-3 provides light vehicle and anti-infantry capability to 3,000m, as well as hunter-killer and slew-to-cue capabilities. The mount is fully stabilized and is able to be used effectively while on the move, and incorporates F50 NGVII image intensifying tubes for night operations.

Additional Features:
Feel free to list more features as you see fit, in more categories.
Crew Comfort
1. Heat management: To reduce the rate of crew fatalities and electronics failure when operating in the Mojave and Sonora Deserts, the vehicle is fitted with a 15,000BTU mechanical cooling system in the turret radiating through the bustle storage bin, and a secondary 6,000BTU unit in the hull connected to the engine radiators. They are controlled by an automotive type thermostat system, incorporating temperature and fan speed controls. Air intake is filtered through the NBC protection system. Heating is provided in the turret by electrical heating elements in the air conditioning system, and in the hull by heat from the engine or APU radiator.
2. Potable water storage is provided for 100 litres, providing 4L per crewmember per day for seven days, with a little extra. Provisions are made for the internal and external stowage of water in one- and two-liter canteens and 20-liter cans.
3. Boiling Vessel. Allows cooking rations for the crew and infantry, and hot drinks during the winter.
4. All crew stations are provided with significantly more room than in legacy vehicles, with an average of 1.5m^3 per station. This is due to the turret shaping and removal of the loader’s position. This is also vastly more area than in either the M1972 or M1A1 tanks, or the Cascadian M2240 Medium.
5. Ammo loading - the automatic loader can be used to mechanically store ammunition in the Carousel, reducing bombing-up time and crew fatigue.
6. The use of a bore evaluator and NBC overpressure System reduces the inhalation of gasses known to the Californian State to cause cancer and reproductive harm by the crew.
Upgradeability
1. Modularized suspension allows replacement with either tube-in-bar designs or hydropneumatic types, or simply replacement of torsion bars, in field conditions with minimal hassle.
2. The novel modularized armor package concept provides extremely high upgrade potential at very low cost and difficulty of upgrading, and allows the replacement of damaged arrays in the field.
3. While the VPK-3 powerpack provided truly revolutionary power in a compact package, the possibility of further improving efficiency is accounted for in the generous dimensional space provided. Upgrades are as simple as swapping the powerpack.
4. Sufficient SWAP-C is available for greatly increased electronic fits, and investigation is being conducted into hard-kill active protection systems, thermal imaging, and laser rangefinders, although these are in the prototype phase, and require further development before large scale deployment.
5. Novel autoloader of AL type allows the development of cartridges of overall length of 975mm, although current cartridges are designed to 950mm.
6. Significant space savings and repositioning of ammunition racks allow for the addition of up to 12 extra rounds of ammunition in hull stowage, bringing the ammunition supply to 58 rounds.

The shock worker-engineers of Sierra Nevada VagonZavod (SNVZ) received a request for proposal of the Heavy Tank 2250, and set out to radically reshape the current paradigm of the heavy tank through scientific discovery and the application of true Marxist-Leninist principles as intersectionalized by Hubbard, Harris, Feinstein, and the other great thinkers who founded our ideological system. The requirements were found to be a worthy challenge, but the current pattern of heavy tank was found to be extremely regressive and problematical. Concurrent developments in electronic computers, by the team under Comrade Academician CkFinite offered great promise in many areas, while the implementation of a multitude of advances in tank technology, and liberal application of L. Ron Hubbard Thought, offered the capacity to reduce vehicle weight and meet the required specifications. The AFV-50 program was therefore governed by three guiding principles, the Three 50s: no more than 50 tons, no less than 50 years before obsolescence, and no more than 50% the unit cost of competitors vehicles.
The performance of the main armament were set not by the current state of the art of the enemy vehicle — it is highly likely that the Cascadian running-dogs will upgrade their M2240 medium tank with the revolutionary reactive armor concepts that they have inevitably stolen from our shock worker-engineers through some perfidy, requiring performance greatly in excess of the lethality requirements. SNVZ therefore chose to use rough estimates of the competitor vehicles’ performance, and the determination to produce the best armament Socialist-Dianetic methods can produce. They have succeeded. With aid from special forces Shock-Archaeologists and the SMVZ advanced technological development team, a survey was conducted to develop the most effective and efficient means of producing a tank, and to determine the state of the art. From this survey, it was determined that the current industrial base is roughly the equivalent of that available to the Union of Soviet Socialist Republics in approximately 1961. The survey showed that the state of the art in electronics standpoint was roughly equivalent, but further developments have rendered this moot — we are on the cusp of a revolution, and have determined means to produce electronic minicomputers and even microprocessors (the latter to a very limited degree) of approximately 10x the power of existing systems for less than 1/50th the cost. Additionally, it was determined that similar techniques would enable new radio electronics.
Following the survey, SNVZ shock engineers and program management teams determined that the pre-war Soviet Union M1972 heavy tank would be an acceptable advanced, yet rugged starting point. Research showed that the vehicle M1972 “Ural” and M1972A is well within the capability of the industry to construct aside from laser rangefinders. While this design was a very good vehicle, SNVZ knew that the outdated non-intersectionalized Marxist-Leninist-Stalinist principled guiding that design team were no match for L. Ron Hubbard thought, and set out to redesign the vehicle.
From this baseline, a series of improvements were suggested by the Political Division to the engineering divisions, to better suit the heavy tank to the Californian environment, as well as to apply the lessons learned throughout the service lives of the vehicles studied, as well as systems designed for the Soviet Union Object 187 heavy tank prototype and M2014 heavy tank. The list of suggested improvements was as follows:
1. Improved armor
2. Crew water stowage.
3. Improved automatic loading mechanism using single-piece fixed ammunition.

17. Electrical turret and gun drive
18. Fully stabilized independent commander’s machine gun with remote operation and capability to overmatch Deseret snipers using 12.7mm rifles.
20. Improved frontal hull armor

28. An electrically-heated water kettle to provide hot rations, and the provision to affix a distillation-purification system for bulk potable water production.
29. Ammunition load of no less than the M1972 Heavy Tank
30. Improved ride quality
32. Incorporation of advanced secure telecommunications systems for crew intercommunication and vehicle-to-vehicle radiotelephony using the latest encryption methods.

36. Drive system packaged as powerpack to allow easier repair and maintenance.
37. Optional hard/soft-kill active protection system
While not all of the above changes were incorporated into the final vehicle, and the resulting vehicle bears more resemblance to the Object 187 prototype than the M1972 it was derived from, it is a wholistic improvement on prior art, and deconstructs, disrupts, and defines the concept of the heavy tank, in the pursuit of the Three D-s of Comrade Feinstein.
The design was prototyped, and it was found to perform better than the wildest specifications from the tankists. The turret is protected from all but the most directly rear angles from the most dangerous chemical penetration threat, the Cascadian pig-dogs’ 60mm/160mm diameter HEAT warhead in their BGM-1 guided antitank rocket. In fact, in the frontal 80-degree arc, it has protection from an 1100mm/1500mm RHAe tandem HEAT charge and an 800mm RHAe kinetic penetrator! The hull is similarly well protected, using a novel special armor array in lieu of the previous steel and textolite composite arrays, saving over 3,500kg (reducing the M1972’s characteristic front-heaviness) compared to the previous designs. Ammunition is protected through the use of innovative wet-stowage systems in the hull ammunition rack, increased armor protection to the automatic loader carousel, and improved, less-sensitive propellant blends.
Despite all these novel features and protection levels comparable to the American M1A1HA, the Object 138 as delivered has a combat weight of under 48,000kg, a growth of less than 3,000kg compared to the M1972 heavy tank upon which it is based. When combined with improved engine output and the CD-1750 crossdrive-type manual transmission found in the VPK-3 powerpack complex, the Object 138 prototypes have demonstrated very high speed, in keeping with the rapidity of the vanguard forces of the DPRC.
The prohibition of use of armor piercing fin stabilized discarding sabot-type projectiles was met with great relief by the aerodynamicists and engineers of SNVZ’s ammunition development team. It was met with similar relief by the armor development team, and they quickly took in hand an example of the 2A35 125mm smoothbore gun chosen for the vehicle, and developed the 3BM family of kinetic energy threat simulator test devices, including the 3BM3, a multi-segment design, which was theorized to be similar to types of perfidy under development by the Cascadians. The armor packages developed are proof to this most abhorrent of projectiles, and testing demonstrated its lethality against the Cascadian M2240 medium tank. Truly, they will be like lambs to the slaughter against the might of our armored vanguard.
