Because I'm not Slavic. My psycho-social gestalt is firmly on the praise good/romantic idealist end of the spectrum.
 
My patience is also a finite resource, especially when getting lip from someone I'm in the process of trying to gently correct instead of chastise.

Cool your jets with the conspiratorial stuff.
 
LoooSeR is one of our most experienced and valuable posters, and provides something that every project needs in his role as a judge: terminal slavic pessimism. And he does so without fear, favour or bias.
This is a man who could look upon the face of God himself and then provide detailed commentary on elements in need of improvement. And we're damn thankful for it.

I'm Armenian-Georgian mix, my parents are from a village in Southern Georgian region near Turkish border. There are several german members in this forum, who i respect. I don't care about nationality of people.
 
   You need ability to follow guidlines. I threw people submissions from competitions for less than that, like during one of previous competition when i excluded this forum owner's submission literally because of several mm. Your submission was not getting any favorable or unfavorable treatment.

This is FUTURE TEXAS, son. We measure our armour in fractions of 16ths of a mile and like it.

I occasionally play this mental game where I imagine describing, let's call it the Schwer-mittel panzerkampfwagen 44 "Cougar", to the typical wehraboo.
 
"It had a low profile, only 10cm taller than the PzIV. But the vehicle is much more heavily armed and armoured (equivalent or better to a Tiger frontally, only a little thinner on the side)."
"Fantastic. Really good, compact design. The Germans were known to be good at efficient layouts."
 
"The drivetrain was extremely compact and reliable, with a better power-to-weight ratio than PzIV, as well as a slick automatic gearbox that reduced workload on the driver and improved offroad mobility."
"Wonderful, truly a vehicle for mobile warfare. Didn't Guderian say, after all, that the principle weapon of the tank was its engine and radio?"
 
"The vehicle had lots of vision devices, a large, roomy interior and nice-to-haves like panoramic gunner's sights and an azimuth indicator in the commander's cupola."
"Brilliant. We know that the crew which sees the target and fires first usually wins. This all adds up to an improvement in firepower!"
 
"Over 2000 were produced in less than a year, making it a relatively common sight on the battlefield when compared to older heavies such as Tiger."
"That's great! Wars are won by industrial production as much as by feats of arms - look at the miracles that Speer accomplished."
 
"It had lots of upgrade potential. Prototypes were produced with guns and armour equivalent to Tiger II, but without completely sacrificing either mobility or reliability."
"This is what made the Germans so formidable during the second world war - their ingenuity and ability to improve on existing designs. If only it had been fielded for longer, it would have had the potential to turn the tide of the war."
 
"It was made by Americans."
"Oh, it's absolute shit then."

So firstly, yikes (context to follow).
 
Secondly, in case you're confused about the rather critical eye we're casting on your no-doubt sincere bit of worldbuilding: we're an old forum by internet standards, tracing our way back, if not to the Sumerian era of usenet groups or the Assyrian era of blogs-turned-forums, then to the classical era of the 2010s. So we've seen some cycles recur. And one of those cycles, analogous to the friendly Nazi problem that bars deal with (only more cringey and sad than disgusting), is the friendly wehraboo problem.
 
You see, they always start friendly - just asking questions, just wanting to air their legitimate love of technology and design independent of the political nastiness that surrounded it. And it always ends in a welter of "which German tank ace would look the hottest as an anime princess" posts. So when some unfortunate soul comes in just asking questions and wanting to air their legitimate love of technology etc etc, we tend to stare hard and long at the underlying dynamics of the situation.
 
Because nobody wants to have to clean up the shit that wehraboos excrete once they congregate in any numbers.
 
 

Europe is sleeping in the shadows of a recent past it pretends it has escaped. All that old evil it spent a century bleeding itself and the greater world dry over was not exorcized by a generation of consumerist socialism. It'll be back a second time - as farce rather than tragedy, of course.
 
I think you know fokkol and should stop before you embarrass yourself.

The full name of this combat vehicle is: TCV-47 "Brahman" (Tracked Combat Vehicle)
 

 
No, it's not done, i took a very long break; burned myself out. But since then, I have added commander's and loaders cupolas', vision slits, drivers hatch, turret roof applique, 12.4 tons of hull armor, and 7 tons of turret armor plus a 4.6 ton turret wedge a la Leopard 2A5. Still needs turret storage boxes, hull roof applique, and side skirts. Ammunition and velocity is going to be similar to that used on the M551 of yore, including a gun launched ATGM based on the BGM-71.

Vehicle designer’s notes:
 
The Derebus family of vehicles (provisionally named Derebus and Derebus-M) are intended to fulfil a procurement strategy emphasizing mobility (tactical, operational and strategic), reliability and superb value for money, achieved using a lightweight vehicle design, proven automotive components and a high/low capability mix. Derebus sports a state-of-the-art fire control system allied to a powerful 5" gun, while Derebus-M provides supporting firepower and a larger ammunition load thanks to it's 4" gun. Both vehicles provide superb protection across their frontal arcs, with the Derebus making use of cutting-edge composites to save weight. Both Derebus and Derebus M are immediately available to fulfil all of your defense needs.
 
Vehicle feature list:

Mobility:

5.     Engine, transmission and cooling are arranged in removable aluminium tub housed in engine bay. The tub is removable by sliding out the rear of the bay.
6.     Suspension - torsion bar, variable travel (presently 11.8" (30cm)), 20" (0.5m) ground clearance, geared torsion bar suspension, each axle pair in detachable units shrouded by aluminium housings. Wheels are 23.6" (0.6m) in diameter, with a track width of 27.6" (0.7m) and a pitch of 7.7" (0.195m).
 
Survivability:
 
1.     Link to Appendix 1
2.     Link to Appendix 2
3.     Non-specified survivability features and other neat tricks - highly sloped turret and hull front (75 degrees), charges and active ammunition (HEAT-FS and HE) arranged in sealed tubes leading to a blast chimney that outlets to blow-off panels in the turret roof, turret sides, hull roof and hull sides.
 
A.    Weapons:
 
1.     Link to Appendix 1
 
2.     Main Weapon-
 
a.      Type: smoothbore, vertically trainable +15/-10 degrees
 
b.      Caliber: 5"/127mm
 
c.      ammunition types and performance:
 
Note: the armour used for the target has the same hardness (360BRN) as the armour used in the vehicle. The target was at 0 degree obliquity for calculation purposes.
HEAT-FS (low-pressure setting): 46lb (20.85kg), penetration of around 21" (535mm), 3074fps (937m/s). HE (low-pressure setting): 46lb (23.2kg), 201oz (5.7kg) fill, estimated blast penetration of ~55mm RHA, 2910fps (887m/s) APFSDS (high-pressure setting): 15:1 LD, 550BHN monosteel body, tungsten insert, 115mm cap, ring sabot, 1800m/s, 15.7/13.8" (400/350mm) penetration at 100/2000y (lower estimate, 17.1" (435mm) at 2000y upper estimate). d.     Ammo stowage arrangement - 19 charges, 9 active projectiles, 10 inert projectiles in turret; 16 charges, 8 active projectiles, 8 inert projectiles in hull.
 
e.      FCS:
Duel axis stabilized main gun Semi-autoloader: the loader places the charge and warhead on trays in the bustle. these are then fed into the gun using an automatic mechanism (horizontal rammer, pivoting loading tray and rigid chain actuator to ram the warhead and charge home). The gun automatically returns to the loading position after each shot. A short spring at the end of the actuator helps to smooth out the loading impulse.  
f.      Neat features: 
Gun has a high-pressure and low-pressure recoil option, selectable on the slide – this doesn’t affect the recoil mechanism, it just changes where the trip key is to unlock the breech (warning: don’t fire high-pressure ammo with the low-pressure setting selected!) Gun uses a separate 6.9x27" (175x685mm) charge: 44lb/20kg mass, semi-combustible case built along the lines of the 4Zh-40 charge used with the historical 125mm 2A26 gun), matching the length of the HEAT-FS round. The charge gives space to produce a more powerful round to match higher future barrel higher pressures (when using a secondary charge with the APFSDS projectile itself). 74000 PSI (510 MPa) gives a potential power of 15MJ. 94000PSI (650 MPa) gives a potential power of 19MJ. Final penetration potential of the gun with early monobloc DU projectiles is something in the region of 22" (550mm) at 2000y (putting it on par with Mango and Vant). Being able to store and handle a longer projectile (ie: above 27") would probably allow something a bit better than Snivets.  Low-pressure charges are shortened (17.1" / 435mm) and come with an ejection spring to work with the same storage tubes as the high-pressure charges. 3.     Secondary weapons - 3 x .30 cal MG, 1 coaxial, 2 in mountings attached to the commander and loader's turret hatch
 
4.     Link to Appendix 3. 
 
B.    Optics:
 
1.     Primary gunsight: single axis stabilized gunner’s sight
 
2.     Secondary gunsight: vertical coincidence rangefinder (stadiametric, 39.4" (1m) base), doubles as a redundant back-up sight.
 
3.     Miscellaneous optics:
Commander and loader's rotating hatches, including vertically trainable (+/- 15 degrees) periscope in front of hatch, degree markings on hatch ring to allow rough direction of gunner to target. Driver's periscope, vertically trainable +/- 15 degrees  
C.    FCS:
 
1.     List of component systems, their purpose and the basic system architecture:
Simple electronic gun-follows sight fire control system (encoder connected to sight mirror feeds elevation data into a transistor-based PID controller, which tries to match position on a similar encoder connected to the gun. When gun position and sight position align, the firing mechanism is electronically triggered). LRF mounted above barrel, solid-state components, maximum operating range of 5km in clear conditions, average estimation error of 1%. Uses flashlamp-pumped ruby laser, optical sensor, quartz timing circuit and the sequential event time sampling approach (with post-sampling amplification) to allow time-of-flight rangefinding using a lower timebase and bandwidth compatible with current electronics.  
2.     Link to Appendix 3.
 
Fightability:
 
1.     List vehicle features which improve its fightability and useability:
 
Engine bay approach simplifies engine and transmission replacement via rear bay doors. Generous rear hull roof hatches simplify servicing and maintenance. Bolt-on suspension units simplify field replacement and repair. Commander and loader's hatch design improves buttoned-up visibility

BAE Systems’ FV601 “Cossack” is a fighting vehicle intended to not only meet all the requirement, but also exceed them, especially mobility requirements. The design also emphasises ease of maintenance and upgradability,  making it the ideal vehicle for the current as well as the next fight.
The FV601 is offered in two configurations: a base configuration, which was designed to achieve every requirement and counter the current threats of the battlefield while offering ample room for upgrades; an add-on FIBUA (Fighting In Built Up Areas) kit, to be installed on vehicles deployed in an area of operation where heavy urban fighting is to be expected. The FIBUA kit can be added to any base configuration “Cossack” in the field in a few hours, not requiring more than hand tools (except the installations of the barrel, requiring light engineering support).

The idea that no modern tank can achieve protection across more than a limited frontal arc jives well with the fact that modern tanks do well when crewed by competent soldiers and die in droves when crewed by Saudis or Iraqis. If your magic armour only works from the front (and then only in certain spots) you need to be good at your job to stop people from flanking you.

The sky's the limit, bud. You go make the 188-tonne tank with two main guns that you've always been dreaming of.

Upgrade a tank - 1970’s (based on Fix a tank - 1943) 
 
It’s the middle of the Cold War, and tensions are high throughout the world. 3rd world countries are trying to buy tanks to protect themselves from foreign aggressors. Pick a tank built and produced before 1952, and upgrade it with equipment and technology available by 1970. First gen LRF’s, second gen i2, and ERA are available (NERA is not). Completely replacing the turret is an option, though expensive.
