Development of the T 40 tank was suggested by the Škoda company under the TVP (general purpose tank) program in 1946. The vehicle design was developed; however, a prototype was never built.

Small gun in tall turret means very good gun depression - easily 15, possibly even 20 degrees. There would still be a big piece of turret above the gun to shoot at when working ridges though. Armor is good enough to bounce most of the low-caliber guns, especially if angled.

Interesting feature of the tank is its front - there is no chasis in front of turret, although tracks make it look a bit like there is, meaning that many noobs may shoot you there for no damage (outside detrack).

The tank isn't very fast, but it's not slow either and would have very good p2w ratio for decently armored medium. The turret makes it a big target and the tank wouldn't have good camo, but it would have very good viewrange.

New tank conception designed by Tatra in 1936, that evetually got patented and turned into project. Point of the concept was to have maximum armor with minimal weight, good visibility for driver and effective space ergonomy with everything inside one big, well armored turret. Project planed to use double chasis of T-78 (T-III), but as T-III turned out to be a complete failure - especially the engine, no prototypes were ever built. In 1938 patent was awarded to Tatra for this tank conception.

Historical LT vz. 34 is sadly rather underwhelming vehicle - only firepower is comparable with LT vz. 35. The 15mm of armor is useless and the engine power makes this tank more sluggish than most heavies (below 9 hp/t ratio).

There were many tanks and prototypes that could fill in the role of tier 2 light tank vehicle, but the LT vz. 34 is certainly of greatest importance thanks to actually being accepted in service and manufactured in greater numbers (50 + 1 prototype).

While some were used as small fortifications in Slovakia, the vehicles never really saw combat and were eventually scrapped.

As LT vz. 35 became the main tank of Czechoslovak army, LT vz. 34 was considered for recon role, but that didn't really work well since the tanks were slow and noisy. In the end the tanks were used for traning.

Light tank, pattern 34 was the first Czechoslovak-made tank accepted into service. Development started in ČKD in 1932 with prototype finished late 1932. After mostly positive results of both company and army tests, 50 vehicles were ordered and accepted into service in 1935. By then it was already obvious that 15mm of armor would be insufficient in combat.

First Czechoslovak tank to be accepted into service. It quickly became obvious that 15mm of armor won't be sufficient in combat and the tanks were soon replaced by LT vz. 35. One prototype and 50 series vehicles were made between 1932 and 1935. By the time WW2 broke out the vehicle was already outdated.

The gun has decent PEN an bad alpha, also bad gun depression, but compensates for it with good burst potential and decent reload time. Tank itslef is small, stealthy, mobility is decent, although not entirely scout-like.

Stronger of the proposed engines is used and the mobility isn't great - ground resistances boost will be required. Maximum speed of 48kph also sounds more like a fast medium - considering that TNH nA did over 70kph with basically the same chasis (although that was probably a ton or two lighter vehicle), I've buffed the top speed to 65 kph.

This was a post-war project for a tank built on the 38(t) (TNH) chasis. It featured sloped frontal armor as the one on Jagdpanzer 38(t) and newly designed sloped turret that could take the 57mm autoloader Škoda gun. It was planned for export, however Soviet Union made arms export practically impossible, so it was cancelled. Partially built prototype may have existed.

Post-war project from 1949 for a light tank for export. As Soviet Union de facto banned arms export on the same year, the project was cancelled. Partially built prototype or technology demonstrator may have existed.

Good ground resistances and maneuverability, nice viewrange and workable penetration on the 20mm autocanon should make this pretty decent gift tank. Gun handling and soft stats not so great though.

There was no radio on early AH-IV vehicles. Also I don't have any idea how the turret might've looked. The pic is a simple montage. The rest is based on AH-IV-P wich should be the basis for AH-IV-C. Gun elevatiin/depression are effectively balance parameters here.

When Lithuania started looking for some armor at the end of 1935, Praga responded with AH-IV-C - an AH-IV variant with 20mm Oerlikon gun. In the end Lithuania chose to buy some tanks from Vickers and AH-IV-C never came to existence. Later when Sweden became interested in AH-IV, the AH-IV-C was again mentioned, along with possibility of AH-IV-D, which was supposed be a "bigger, heavier version" - I have no more info on that though. In the end Sweden chose to use modified AH-IV-R instead.

Tankette based on TNH-style suspension was first built for Persia (AH-IV-P) - 50 vehicles were built between 1936 and 1937. Meanwhile, Romania and Sweden also got interested in those vehicles and AH-IV-R became known as the Romanian R-1 (35+ vehicles) and Sweden accepted AH-IV-Sv as Strv m/37 (48). Etiopia bought about 20 in late 1940s.

AH-IV tankettes based on TNH design were exported in several variants to Persia, Romania, Sweden and Etiopia - over 150 AH-IV tankettes were built between 1935 and 1950. Besides the produced vehicles, there were also few unrealized project variants. At least one of them, AH-IV-C (1936 offered to Lithuania, later to Sweden), was supposed to mount a 20mmm Oerlikon gun.

The guns lack premium ammo (might come up with some fake enhanced HEAT if necessary), but the penetration of standard HEAT shells is best of the tier X LT guns. Now while a single shot does measly 220 DMG, player should be able to shoot both guns at once - without any issues like charging the shot - delivering 440 DMG in single burst. Having 2 guns makes reload mechanism tricky, but basically it can act as standard clip with nigh-zero interclip reload and 10-15s full clip reload. The shell velocity wouldn't be great, neither would the gun accuracy, but on short to mid ranges the guns should be very effective.

This would be the ambush scout, as small size with great mobility makes it ideal for stealth ambushes and active scouting. However, low weight and lack of armor means that 1) everything will overmatch it 2) collisions with other tanks are likely to be fatal.

Well, the elephant in the room are the recoilles guns, which are not currently an option for WoT vehicles (not quite sure why though), and neither is having dual guns, which would require some new reload mechanics. Other than that, this would likely be the best option for tier X light vehicle.

Ideas for alternatives to Š-971 evetually led to a new armored car project on the same T-805 chasis - this time armed with a pair of the 82mm vz.59 recoilles guns on a fully rotating turret. The task was assigned to Tatra Kopřivnice, which came up with Tatra T-811 vehicle, better known as OA-82 Jarmila II. The prototype was built in 1958. The vehicle was successfully trialed, however the mass production has been cancelled in early 1959 due to lack of production capacity.

AZNP Mladá Boleslav (aka nowdays Škoda Auto) was tasked with the project and came up with Š-971, also known under the project codename "Jarmila". Three prototypes were built between 1954-1955, however due to issues with engine overheating, the project was eventually cancelled in 1956. One of the prototypes was used a demonstrator vehicle for the new 82mm recoilless gun in 1957, but all prototypes were eventually scrapped.

With wartime armored cars phased out of service, Czechoslovakia found itself with no armored cars in the early 1950s. As a result of this, project for development of new vehicle of this class was started in spring of 1952. The vehicle was to be based on Tatra T-805 truck chasis, armed with machine guns, with weight under 4 tons.

Armored recon vehicle armed with a pair of 82mm recoilless guns on a rotating turret. Developed by Tatra, the prototype was sucessfuly trialed in 1958. The vehicle did not enter mass production due to lack of production capacities.

The 100mm gun is mix of various D-10 gun and ammunitions from T-54/lwt with full 320 damage - expecting not very good soft stats, depression/elevation angles or turret traverse. AP penetration is on the low side. Other than that, same as tier 7 LT pretty much.

100mm is a T-54 gun, one of the versions license-produced in Czehoslovakia. It would fit in the turret, not sure about recoil though.

The 85mm gun is only there for stock role, although the 105mm howitzer of Zb5915 should have some mount parts rather similiar to 85mm A22 gun.

Rather than having this as Zb5915 with unhistorical upgrades, I've decided to make it de facto fake vehicle. This is basically the Zb5915/16 vehicle with bigger guns.

WG is generally against adding amphibious vehicles into the game, although imo as long as no one expects them to actually float, they might not care too much about that.

Frankly, I don't like it. It's huge target with no armor - literally a huge xp pinata, guns have bad gun depression because of the low-profile turret. Soft stats should be padded as possible.

Quite a big scout. Has great specific power and top speed and resistances and good RoF. The tank has no armor a won't take ramming well at all. Gun depression sucks, but other handling stats are good and DPM is relatively great. Although the turret itself is quite low-profile, the hull is in fact taller than T-54 hull. It's kinda like Skautpanther with better gun that cannot ram things. Or bounce things >_>

The second turret is fake - basically an enlarged version of original turret to provide some gun depression for the 76mm and 85mm guns. I don't really think that the stock turret could actually take an 85mm gun in a meaningful way and turret redesign would have to happen if that gun was to be used imo - that's all there is to it. It's really just my guesstimate - could be removed, should WG feel extra historical, but for now I'll keep it there.

There were two models of the vehicle - one on the picture and other with a pike nose. I would suggest using the one with the pike nose as it looks better and will probably have better gun depression.

This was design for a amphibious tank requested in 1954, based off different amphibious vehicle and to be using the 57mm autoloader. Several models were built to measure its hydrodynamic properties and the project was sent to Soviet Union for evaluation. The evaluation ended favourably: Soviets suggested installing a bigger gun (either 76 or 85mm) and weaker engine (the 200hp V-6), but overall considered the project to be better than Soviet PT-76. Regardless, the project was scrapped in 1956.

Project for amphibious tank from 1954 from factory in Martin was positively evaluated in Soviet Union. Nontheless, further development was stopped in 1956. Only models for hydrostatic testing were made.

Relatively historical. I'm using this TD as a light tank, since it's fast and small. Speed is buffed, though depends how you look at it - project only states minimum speed.

SPG projects based on LP platform propesed by Škoda - intended as mobile light turreted tank destroyer (Zb 5916-S) or light howitzer (Zb 5915-S). Concept vehicle based on Ministry of National Defense requests from 1948. Never got to development as the LP chasis project was dropped.

Frontal armor of this tank is actually pretty decent thanks to its sloping and occasional bounce may happen. Speed on the tank is pretty good and while bigger than the previous tanks, the overall size is still pretty small.

The 75mm A26 Škoda autoloader is essentialy the same gun as the top gun on T 25, only with fully automatic loading mechanism. In game Id give it worse accuracy and aimtime with huge bloom after firing, but very fast RoF between shots - effectively could empty the 3-shell drum in a second, but without letting it aim like that it would be highly unlikely to actually hit the target. Mid gun should behave like on T 25, except with worse soft stats and while A26 should have an andge in DPM, all three guns should be a viable option for this tank.

Gun intended for the vehcle was 75mm A26 Škoda autoloader - previous guns are there to have something to research. The engines were never really specified - the stock engine should fit the tank and fits the request for 200hp engine well. The other two were just mentioned in vague terms that more or less make up their description in the tree. Radios were probably never specified.

Škoda company's proposal for a new light tank as well as new light platform. The tank had fairly modern design, but it never made it past the drawing board. Since the Czechoslovak army wasn't interested in new light tanks and exporting taks was virtually impossible under the Soviet influence, the project was ended in early 1950s.

Škoda project from 1948 for a new light tank built on a new suspension. The project was cancelled in early fifties with no prototypes made.

The vehicle is slightly lighter and thus slightly more maneuverable than T 15. Sloped armor won't help much, but some mid-caliber HE rounds won't pen it frontally. The 47mm autoloader has sub-par penetration, but good soft stats, including fast drum reload time. Other than that, same as previous vehicle.

For A25 (see TNH 57/900, Leták) the numbers got me 110-144mm penetration, but in most cases 129-131mm. 130mm it is then.

For A24 I mostly ended up with results of cca 87-90mm, but some went as high as 111mm. For now I'll stick with 90mm, though greater buff wouldn't be out of question for Škoda T16.

Regarding the A24 and A25 penetration values. I've eventually tried various ways of approximating the gun's penetration for WoT (100m flat). I'm no expert, I mostly used values from guns with similiar performance or properties and extra/interpolated with that, getting various results with various source data. Basically, I think the A23 autoloader already present in the game is somewhat buffed from cca 70mm of PEN to ingame 82mm. With that in mind, I buffed the A24 and A25 results in similiar manner.

The 57mm A25 autoloader gun was also mentioned as being tested on this vehicle, it may be added as new top gun if A24 appears to be lacking.

The second turret is in fact a T 12 turret, aka one of the turrets from upgraded export versions of LT vz 35. It is said that LT vz 35 turret was used on a T 15 in attempt to quickly press the prototype into service near the end of the war, but war ended before that could happen. Also this turret was able to take a 47mm gun, which makes it a good choice for the above mentioned gun testing.

As I said, not much data is available. I used most things from T 15. T-103 should be the engine intended for T-16.

The photo used for an icon is the closes thing and pretty much the only usable image of T 16. Hell Im not even sure it is the right tank, but it was described as such and the suspension does look a lot like on T 15 and it does seem to have the sloped frontal armor. So unless I find some more reliable data, this is T 16.

Not much is known about the T 16 tank - it was a development of T 15 with sloped frontal armor and it is said that Škoda autoloading guns were tested on it.

Further development of last Škoda T 15 prototype. It featured sloped frontal armor and was used as a testbed for some of the Škoda autoloading guns. No more prototypes were built.

The 5cm gun has better penetration stats than it's German counterpart, which is nerfed compared to reality, fow whatever the reason may be. (The PEN numbers are historical, but for a 30° sloped armor.) Anyway I buffed it to more proper levels for use in Czechoslovak tree.

Basically the German tier 3 premium with upgrades, made historical. The most obvious difference is the second turret with 5cm gun. Now not much is known about the turret, but all things considered, the VK 16.02 Leopard turret seems to be the closest real thing to whatever was intended for the tank. So, yeah, basically a T-15 with Luchs turret. The turret and the gun of course make the tank noticeably heavier.

Stock configuration reflects the variant that underwent the trials. (Expcet maybe for radio as I'm not entirely sure which one was used.)

In case the tank would get manufactured, a new turret from Daimler-Benz was planned for it, which would mount the 5cm KwK 39 L/60 gun.

When Germany looked for a new scout tank in 1940, three manufacturers submitted their prototypes: MAN submitted the VK 13.03, ČKD(then BMM) submitted the TNH nA and Škoda entered with T 15. In the end MAN won the contract (although the TNH nA proved to be superior during the tests in 1942) and VK 13.03 came to be known as Luchs. Škoda T 15 was deemed unrefined and returned to factory. Škoda built total of 5 prototypes between 1941-1945 and continued on imporving their design, but all were eventually scraped.

Škoda T 15 was one of the contesting designs for new reconnaissance vehicle for german army, however during the trials the tank design was deemed as unrefined. Five prototypes were made between 1941 and 1945.

Hull is the one of T 21. The stock setup should otherwise correspond the first Š-IIc prototype version. T-21 would get the 2nd engine. T-21 as planned for Hungary would have the 40mm gun. T 22 came with the top engine. T-23M turret got 50mm frontal armor and new gun in form of A11 and of course the second set of tracks corresponds to it. Radios are as usual guesswork.

In the end the remaining prototypes were shown to CS army after the war, but since they were already utterly obsolete, the tanks were scrapped in late 1940s.

T-23M was the last of the Š-IIc prototypes. It was developed along with T-22, having 50mm of frontal armor and simpler, more reliable chasis. By 1942 it was a very reliable but also outdated machine.

T-22 was a turretless prototype from 1940. For a while it seemed that Germans might actually want a tank based on this vehicle, but in the end war situation changed their mind. A tank destroyer Voss I with 75mm gun and SPG Voss II with 15cm howitzer were designed on the chasis, but were never built.

Škoda continued to work on the prototype, which eventually came to be a rather good tank. By that time the cuntry was already under german occupation and the project was renamed to T-21. While Germans didn't show much interest in the tank, they allowed it to be offered to friendly states. Romania, Hungary and Italy all showed interest in the tank and Škoda was willing to deliver, however Germany decided that Škoda factories will only by used for German production. The company thus offered a production license, however only Hungary had resources and technology to license-produce the vehicle. And eventually, in 1942, they did just that - the hungarian medium tank 40.M Turán is a license produced T-21 with some T-22 upgrades, 40mm gun and other local modifications.

This tank was developed as Š-IIc, based on the experience from Š-III and ŠP-IIb projects. Development started in 1936 and prototype was made in 1937. As previous medium tank attempts it had problems with the engine and in the end the issues weren't solved soon enough to compete against ČKD V-8-H (ST vz 39) for new Czechoslovak medium tank.

Medium tank Škoda developed for Czechoslovak army. It wasn't quite finished in time to compete against V-8-H developed by ČKD (ST vz 39), but it was further improved and in 1940 the T-21 licence was sold to Hungary, which mass produced the vehicle from 1942 with some modifications as 40.M Turán. Škoda continued to improve the design with prototypes T-22 and T-23M, however no more vehicles were manufactured.

Other than the ammo, it's basically te same vehicle as the one on tier 9. More specifically 5914 was to mount 100mm AT gun while 5913 was to mount 152mm howitzer - the guns come with different mounts so there's also that. But effectively the same thing otherwise.

Engines, radios taken from TVP T-50. The gun is... well, the 152mm howitzer to be used on TVP-based wasn't specified besides it's HE capabilities and approximate length, although it's generally accepted that K7 howitzer was planned for these vehicles. I've decided to use a generic 152mm howitzer name, which gives a leeway for some acceptably fake gun properties. I expect the gun to shoot HEAT as both standard and premium ammo.

Project for turreted self-proppeled howitzer with gun in fully rotating open turret, based on the TVP chasis. Proposed by Škoda as one of several projects that came to existence in 1948 during the meeting of Škoda and CS army representatives. It was to be fast and lightly armored. In early 1950s this and all related projects were cancelled and Czechoslovakia started using and license-building Soviet vehicles.

Fake, see tier 8 TD for actual vehicle. although this is not that much different, it just assumes the AA loading rack for the R11 gun.

Post-war project of tank destroyer with fully rotating open turret, built on TVP chasis. Proposed in 1948, existed only on paper - project was cancelled in 1950/51. (This one is fake, heavy AA gun variant.)

Historicaly, the A20 was the intended gun for this project + there was practically identical project for 152mm howitzer. The rest of the guns are A20 sister projects (R11 is AA variant, AK1 is another 100mm AT gun developed alongside A20 for TVP project).

Engines, radios taken from TVP T-50. The 100mm gun are more or less same as on the previous vehicle. The top autoloader is however a "new" gun.

Project for turreted tank destroyer with gun in fully rotating open turret, based on the TVP chasis. Proposed by Škoda as one of several projects that came to existence in 1948 during the meeting of Škoda and CS army representatives. It was to be fast, lightly armored, armed with 100mm AT gun (variant with 152mm howitzer also existed). In early 1950s this and all related projects were cancelled and Czechoslovakia started using and license-building Soviet vehicles.

There were also turreted variants of the vehicle with same armanent and less armor - that is basically the tier 9 TD.

Radios are guesswork. Stock gun is the one planned, second gun is basically the longer AA version of the same gun. AK1 is a 100mm AT gun developed for TVP alongside the A20. Engines taken from ingame TVP T-50 to give it good speed.

Project for tank destroyer with construction similiar to Jagdpanzer 38(t), based on the TVP chasis. Proposed by Škoda was one of several projects that came to existence in 1948 during the meeting of Škoda and CS army representatives. It was to be fast, lightly armored, armed with 100mm A20 Škoda gun. In early 1950s this and all related projects were cancelled and Czechoslovakia started using and license-building Soviet vehicles.

Kinda like the previous TD, but faster, with much improved gun handling. Not quite the pew-pew of E25 though.

There were also turreted variants of thse vehicles with same armanent and less armor - I'm using those as light tanks.

Radios are guesswork. Stock gun was planned on practically the same vehicle as self-propelled light howitzer. Engines taken from T 17, for which the top one was planned.

Project for tank destroyer with construction similiar to Jagdpanzer 38(t), based on the LP chasis (originally planned for T 17 light tank) proposed by Škoda was one of several projects that came to existence in 1948 during the meeting of Škoda and CS army representatives. It was to be fast, small, lightly armored, armed with 76.2mm A19 Škoda gun. In early 1950s this and all related projects were cancelled and Czechoslovakia started using and license-building Soviet vehicles.

Post-war project of light tank destroyer similiar in construction the Jagdpanzer 38(t) but built on a new chasis. Proposed in 1948, existed only on paper - project was cancelled in 1950/51.

Faster than Hetzer thanks to better engines available, however the gun handling is bad on both new guns. The 85mm should be cheaper to research and run, but lacking in penetration and accuracy. The 76mm is more accurate, has better PEN, although slightly worse alpha. The tank stays very small and stealthy, though the armor isn't worth as much anymore.

Engines: stock is historical Jagdpanzer 38(t) engine. Second was used on Starr series. Last engine was used on Kätzchen prototypes - recon vehicle / APC also based on the TNH nA chasis.

First gun was used on Jagdpanzer 38(t) prototype, on Starr versions and also on some export post-war vehicles, once the manufacturer ran out of the standard gun. Second gun is the historical standard gun of Jagdpanzer 38(t). 76mm A19 and Soviet 85mm are the guns considered for instalation post-war. 105mm derp added for fun, German proposal for JgPz 38t Starr.

Jagdpanzer 38(t) entered the Czechoslovak army under the designation ST-I. Some 158 vehicles were exported to Switzerland as G13 and 11 more ended in Guinea. In 1950 the army started to looking for a way to upgun the vehicles as tech from USSR was not available yet. The 76mm A19 gun developed in Škoda was considered, but he development of the gun was cancelled. Other considered gun was the 85mm used on Soviet T-34s - that project was cancelled as well.

After the war, the Jagdpanzer 38(t) became the main tank destroyer of Czechoslovak army under the designation ST-I and more were built for export. During the years 1950-1951 army looked into option of upgunning the vehicle with 76.2mm A19 gun. Project was cancelled along with the development of A19 gun. Soviet 85mm was also considered.

Two 75mm guns are mentioned as planned for the vehicles by various sources - A16 seems to be the more likely one. The 10.5cm howitzer gun was not planned for this vehicle in particular, however there was a post-war propsal for a very similiar T-22/23M based vehicle using this gun, and another one with same gun and concept based on Turán chasis, which was also based on T-21 chasis.

Now this proposal clearly expects that wheeled chasi won't be specific to the new "wheeled tank" scout class. And I don't see why it should, especially when DANA is just the kind of vehicle to possibly even justify implementing a new SPG branch.

Wheeled artillery with powerful, accurate and fast-firing 152mm gun in rotating turret. (800dmg/55-60pen @.55-.6 accuracy and cca 3 shots per minute imo). Shell arc somewhat on the flat side. While the top speed is high, the vehicle is a tad underpowered to actually reach it even on hard terrain. Kinda large paper target.

Armor values unknown, but it should handle stuff like HMGs. Not sure about the armor thickness but the rest is fine.

Over the years, the vehicle was also exported to Poland, Soviet Union, Lybia and other countries. Various modernizations were also developed since late 1980s, most notably the Slovak Zuzana line of vehicles, which uses the NATO standard 155mm caliber gun. This also includes the A 40 Himalaya prototype, which is basically a Zuzana turret on T-72 chasis.

Developed as an indigenous and cheaper alternative to tracked Soviet 2S3 Akatsiya, the vz77 DANA was the first vehicles if its kind. The wheeled Tatra 815 chasis made it cheaper to build and maintain, while providing great mobility on roads as well as solid terrain passability.

Self-propelled artillery built on wheeled chasis. Project started in Konštrukta Trenčín in late 1960s, with first prototype biult in 1972. Development finished in 1976 and by 1980 first series vehicles entered service in ČSLA. The production has continued into 1990s with 858 total vehicles built in ZTS Dubinca nad Váhom. Cca 300 vehicles are still in service in Czech and Slovak armies.

Mounting the 15cm howitzer on Panther chasis was an idea from Feb 1947. VTÚ and Škoda agreed on building 2 prototypes and 2 variants with different turrets were presented in documentation sent to VTÚ in July. In August VTÚ changed their request to a single vehicle mounted with 105mm leFH 18. That prototype was finished in 1949, but disassembled in 1950. Chasis was then rebuilt into recovery vehicle.

When the Czechoslovak army was re-establishing its tank force after the war, it was also left with one working Panther tank (and 65 more repairable ones). These were to serve in heavy tank role. First Panther went through general repairs in 1947 and it was decided to repair 40 more Panthers along with 14 Bergerpanthers. 13 Bergepanzers entered service shortly after. Repair of combat Panther were postponed to years 1951-52, after which the army had 32 Panthers in working order. They have however never entered into service - some were eventualy rebuild into recovery vehicles, the rest was scrapped.

15cm sFH 18 altered for use of Soviet 152mm ammunition, mounted on Panther chasis. Originally suggested in 1947, the project was cancelled in 1950 before the prototype was finished.

Not really that different from German Hummel - different top gun is to be slightly better, uses historical engine though, so not as fast.

In 1948, 17 Hummels were gathered, 15 of which were deemed repairable. In the end, 12 vehicles were repaired, their guns rebored for 152,4mm Soviet ammunition. The vehicles served in the army since 1950. The machines eventualy broke down again and were used for spare parts for other Pz IV based vehicles. By 1955 they were no longer listed among their units' equipment.

Top gun is Hummel gun, so it should do rather well on tier 5. No gun depression though.

Radios - no idea as usual. No idea how different were the 10.5cm versions, drawings look pretty similiar, but the drawing numbers are not exactly close. Stock engine is T-21 engine.

Dunno about Radios, the stock gun is kind of there for grinding purposes. Second engine was not used on the prototype, however it was used on some other JgPz 38(t) based projects.

Prototype built by BMM (ČKD) in 1944. Allegedly, 30 series vehicles may have been built in Germany, but there's no evidence to support that claim. Bergepanzer 38(t) chasis was used for the prototype.

About the proposal

This proposal is based on info from several, mostly czech sites about armoured tech (most importantly the valka.cz and utocnavazoba.wz.cz, also for example panzernet.net and occasionaly some other sites I frankly don't remember). WoT wiki and tanks.gg were used when devising pentration stats. Info from following books was used: Českoskoslovenská obrněná vozidla 1918-1948, Exportní lehké tanky Praga, Exportní tančíky Praga, Československé tankové síly 1945-1992 by V.Francev, Obrněná technika 1944-2001 Výroba v Slovenskej republike by Š. Zupko and J. Zupko and Od bodáku po tryskáče by M. Dubánek. Especially the first one on the list was very useful. SilentStalker's articles from FTR were also used for lots various info and as basis for mainly the LT line and some info was takn from Yuri Pasholoks articles on Warspot.ru. This AW article was useful for the Jarmila vehicle.

I got kinda fed up with all this as I was putting together the TD line, which you can probably guess from vehicle descriptions getting pretty short on TDs. So while I was planning to add some details to this proposal, for the forseeable future I'm not making any major changes to the page itself.

Tank stats on the left are always meant for the top config by the way - should be historical, can't say that for sure with some gun depression stats though. Oh and images are not to scale, obviously. Blue backshadow highlights "new" modules (not turrets and tracks), while red module background means the module would be too heavy for stock tracks. Red outline means unhistorical module (not used when only minor details are wrong). I don't go into stuff like aimtime, reload time, etc. besides some approximations in tank details texts. These are ultimately balance parameters. Even the number of shells in magazine is there rather to make obvious it's an autoloader gun. Overall, the module listing is probably what differentiates this proposal most from whichever there were before, although the line setups are also fairly unique afaik.

Default ammo on new guns is AP with roughly historical stats, while premium is APCR, which may be fake on some guns. APCR penetration is approximated. Exceptions now have the ammo types specified.

Penetration value on some new guns may not be historical, but by now all differences should be below 10mm of PEN where some data were available. This is mostly a combination of gun performace needs and similiar WG enhancements already made to some guns. There are some "generic" guns with liitle to no parameters available - these have stats created according to the needs of the tree.

Oh yea - this page probably does not display properly in IE. I was using this to see what can be done with CSS and HTML these days, but I didn't really bother with checking how it displays on different browsers. I used Firefox to make it and I see no issues on Chrome, so current browsers based on those should be fine. I saw some bugs on various IE versions, like borders around images where they shouldn't be, or missing the horizontal slider. Well I'm not fixing that, definitely not now. No javascript used btw. Playing with responsive design on larger scaly sound like a PIA, so it probably won't happen.

By the way if you have any comments or suggestions, you can send them to pipboy@seznam.cz

Mizutayio's Swiss tree proposal - most of the data and images provided by Mizutayio, technical side handled by me.

Polish tree proposal - made by a bunch of people, see their About section. I'm not directly associated with this one - the folks made a lot of modifications to the design.

April 2020

Overall overhaul according to tech-tree changes planned for the game in patch 1.9:

Removed tree tanks: SPGs below tier 5, TDs below tier 4, KSÚ (MT2), Tatra T-78 (MT3), LT-40 (LT3).

Removed premium tanks: Škoda Š-II (LT2), Škoda T 12 (LT3), ST-II (TD4), T51 Koncept (MT8), ShKH-TVP (TD8). Some of those may come back later.

LT vz. 34 turned into a premium vehicle with historical modules.

Atypický tank Tatra dropped to tier 3, top gun removed.

Škoda T 23M changed to Škoda T 21: dropped to tier 3, top gun removed, front hull armor -20mm (=diff. between T21 and T23). Also dropped top radio.

Removed Gvozdika, kept Jarmila II as tier X light. (So what if the guns are recoilless, their effective parameters are well in line with other WoT guns.)

Visual lines are gone and will stay gone for now. They are pain in the ass.

Revamped the TD line - the vehicles have more similiar gameplay style now and are not as underpowered as they were: SD-100 removed. ShPTK-TVP moved from tier 8 to tier 7, removed top gun. Zb 5914-S is now split into 2 vehicles at tiers 8,9: tier 8 lost the top gun, otherwise they are pretty much the same thing. Tier 10 gets an alternative gun with playstyle similiar to tier 9.

Buffed shell damage on Jarmila II from 200 to 220 dmg.

November 2019

Changed stock engine on T-16 to the historical one.

August 2019

Added new ingame tier 8 medium premium Škoda T27. Removed the suggested T-34/100A to make space for it.

November 2018

Added OA-82 Jarmila II as theoretical wheeled LT X. Its armed with a pair of recoilles guns, which is currently a double no-no for WoT. It's more attractive and unique than the Gvozdika though.

Renamed the top turret on T-15 to more familiar name (Luchs 5 cm).

October 2018

Slight buff to 7cm howitzers (MT-2, MT-3, SPG-2) to match the 7cm on Type 91 heavy.

Small change to TD-2 stock gun name.

September 2018

T-34/100A added as a premium tier 8 medium option.

Removed weaker engine from Gvozdika.

August 2018

Penetration values on Škoda A16 gun (TD4) updated according to current ingame version of the gun (which is the top gun on Italian P.43)

Removed J2 optional gun from TD10, buffed the basic PEN and nerfed damage on the basic gun.

Renamed "Praga T 51" to "Praga T 51 Koncept", since its visuals are more of an "educated" guess. (Nice trick, huh?)

Switched tier X SPG Kominík (which smelled kinda fake anyway) to ShKH vz.77 DANA, which is a pretty unique wheeled vehicle with historical significance.

May 2018

Top gun on tier 9 TD now marked as using the ready-rack mechanics. (The thing that Italian autoloaders have.)

September 2017

Added 105mm derp to ST-I, for fun. Also renamed it from ST-I 76mm to ST-I (TNH).

Late June 2017

Switched around tier 4/5 and 6/7 SPGs and buffed damage on 7/8 SPGs a bit.

June 2017

Minor changes to tier 8 TD. Tier 10 TD now gets alternative long 152mm. (I still think it's too long and heavy, but seeing the Swiss proposals kinda makes me not caring about that anymore.)

Updated code with changes from work on Mizutayio's Swiss proposal - should help with viewing tree on smaller screens.

Added link to Mizutayio's Swiss tree.

Late May 2017

Added the SPG line. It's not as nice as I'd hope, Kominík is a bit sketchy, but oh what the hell, it's just an SPG line.

Removed one of the ST-I engines.

May 2017

Some changes to LT9: Removed stock engine and gun, renamed some modules, changed rumored 90mm for actual 100mm. Shorter vehicle name.

Some changes to LT7: Added 2nd turret. Shorter vehicle name.

April 2017

Buffed tier X TD gun.

Removed some info on AK1 guns that was probably wrong.

Changed A20 gun on T51 for AK1 L/53. (More or less same performance.)

Reordered Lights: 5916 is now tier 7, Leták is tier 8.

Removed unhistorical 85mm gun from Zb5916. Now the lights up to teir 8 are almost completely historical stuff.

Added alternative generic name to 85mm LT gun for some extra historicity points.

Added new engine to Leták, reworked its modules tree, removed one 76mm gun.

Zb5915 got some unhistorical guns and is now tier 9 light tank.

122mm ShH 2S1 (Gvozdika) is a new tier 10 light tank. Gets alternative 100mm gun and engine boost. It may suck, but there are no more suitable options.

All gun depression stats buffed to at least -5 deg.

Nerfed 57/900 drum to 3-shot (expecting fast reload instead, duh).

Removed T-55 DANA fake.

Rewrote/updated parts of the About section.

Cleared some dubious stuff regarding tier 9 LT, so it's now a de facto fake. Stock howitzer gun got switched for 76mm.

In turn the LT7 got a 105mm howitzer for a stock gun and 85mm LT gun is no longer considered to be A22.

December 2016

Renamed top td gun, rearranged guns on T 16 for less painful grind.

November 19 2016

Removed Gvozidka tier X TD, used tier 9 with 152mm HEAT spitting version of the howitzer instead. Not as historical, but more Czechoslovak. (Also I'm considering Gvozdika for tier X light tank.)

Removed the howitzer from tier 9 TD.

Name changed on tier 8 premium TD.

There's sone extra text in tier X TD description egarding the other options.

November 2016

Buff to H9 a K7 AP penetrations. (Negligible on H9. K7 however now has 165mm of PEN on AP shells, which ain't too shabby.)

Late October 2016

Added tier 8 MT and TD premiums. The T51 is mostly unknown tank a the moment so the entry is more of a placeholder - THE IMAGE IS JUST MY MOCK-UP - IT IS NOT THE ACTUAL T 51. On the other hand WG may already have enough data on T51 to implement it into the game, which makes it the most likely next Czechoslovak tank in the game. The tier 8 premium TD is nothing new, it was already in this tree some time ago, but I've merged it with the regular one. Well now it's back. Which also means that regular tier 8 TD loses the 152mm derp.

Late September 2016

LTH switched for LT-40. It's less interesting, not as good tank, but LTH may be more useful as Panzerwagen 39 in possible Swiss tree. Also removed the option to research LT vz 38.

When looking at LT-40 details, I've found a mention of AH-IV project using 20mm gun. There's not much details to it, but finally I can add the AH-IV to the tree - yay! (Tier 2 premium light AH-IV-C added.)

September 2016

New tier X TD - 2S1 Gvozdika. Technically also an SPG and not even of Czechoslovak origin in any way, but it is a real vehicle, it was used by ČSLA in considerable numbers and it is relatively balance-able for the role of tier X TD. It uses HEAT for both standard and premium shells.

August 2016

Minor adjustments to A24 (T16) and A25 (57/900, Leták) penetration values.

July 2016

Internally, more stuff is now generated with php.

Renamed some of the vehicles.

New, free fonts from Google Fonts are now used. Most importantly - the font cannibalized from WG site was dropped. The new one is almost identical though.

Adjusted Details textarea.

June 19th 2016

Some major changes to tier 5-7 scouts as the autoloader penetration values (A24,A25) got reviewed and nerfed to more historical values:

T16 top gun got significant penetration nerf. (May gain A25 as new top gun.)

TNH 57/900 is the new tier 6 premium, the previous one got removed.

Leták is now standard tier 7 vehicle rather than premium.

Zb 5916-S - removed second turret.

Slight PEN buff on A22.

June 16th 2016

Some major changes to tier 8,9 TDs: 152mm howitzer and AK1 with 3shot autoloader now available to both vehicles, autoloaded R11 using AK1 ingame ammo (APCR) is now the top gun on tier 9 TD.

Tier 9 TD renamed to its blueprint number.

Removed the tier 8 premium TD.

June 2016

Fixed A22 85mm gun HE PEN.

Changed MU-6 tier 3 TD to more historical setup (it used to be a hybrid of 2 versions of that vehicle): stock turret is gone, chasis corresponds to late design, vehicle weight adjusted to data that seem to be related to late version (imo some of the data on weight must be wrong - seems weird to me that version without proper turret and hull actually weighs 50% more >_>).

Added alternative naming for T-III

Removed top gun from LT vz.34 - was kinda OP an not really needed.

Most fake stuff is now red (top TD, top gun on top scout).

May 5th 2016 - Updated 88mm guns PEN to 9.15 values. (T 40, TVP VTU)

April 24th 2016 - Slight nerf to 76mm guns' alpha. Removed TNH nA premium for having way too underpowered gun. Added Škoda T 12 on tier 3 instead.

April 20th 2016 - Slight nerf to LT8 top gun standard and premium ammo penetrations, adjusted number of shells in LT7 drums. Minor fixes in texts.

April 2nd 2016 - just some small edits to T23M and putting ATT back to tier 4.

March 12th 2016 - Made more changes based on input from people on The Armored Patrol (thanks guys, especially Sebastianul for posting it) and more:

Changed some descriptions here and there.

Removed Š-III and used T-III instead, since T-III has better stats on paper, especially regarding its mobility. Š-III felt seriously underpowered on tier 3. (Turrets and guns were identical and I completely forgot that Tatra had an early wheel-cum-track prototype too. Bottom line is I have almost as many modules on T-III as I had on Š-III.)

Now that ther tier 3 medium doesn't completely suck, I can also move the Atypický Tank Tatra premium to tier 3, where it can perform closer to its intended role. (And save a line space on the tree layout, yay.)

Lowered KSÚ weight with top suspension.

Rearranged modules on Škoda T 23M.

Adjustd values on TNH 57/900 guns.

Removed several modules from TNH - there were way too many. (Removed modules related to LTL, LT-40, TNH-Sv, kept modules related to TNH-P, LTP, LTH). Also fixed the wrong engine values.

March 2016 - I've made some changes:

Nerfed 76mm A19 penetration stats to more historical numbers and providing it with two variants. This affects the tier 8 LT and tier 5+6 TDs.

Added 85mm A22 gun (APCR) + second turret to the tier 8 LT to compensate for the A19 nerf. (Historically it was a field gun, not a tank gun. Should work in theory though.)

Switched T-21 for T-23M - effectively the same thing with better hull armor.

Rearranged some modules, branches, research paths and such.

Removed the SilentStalker's fakes for tier X TD, leaving just my fake.

Added tier 4 TD ST-II and tier 8 TD Zb-5922-S a premium TD options.

Reworked the css so the tree fits better on smaller screens

Fixed some minor technical issues (still not IE friendly)

Edited some descriptons and fixed some of the typos (certainly not all of them - I don't really care much about typos).

When the Czechoslovak tree was introduced into the game, I was happy that our nation is finally getting one. On the other hand I was disappointed that the tree is in fact only a single medium branch. Japanese got their not very impressive light tank line right from the start and we don't? We had more light tank material and they would mostly be proper scouts. And there are some light tanks I was really hoping to see in the game, like the LT vz 34 - first Czechoslovak-made tank that was built in numbers, or TNH 57/900 - really cool looking post-war light tank project. And the AH-IV tankette, one of the few actually sucessful tankettes ever built - now that I know there was a plan for 20mm autocanon version I know it can be done.

Anyways, adding the light branch was the main purpose of this thingy. As light lines were prolonged to tier 10, vehicles on tiers up to 8 actualy turned out to fit the tree quite weel in their historical setups. Problem was with the new tiers - tier 9 and 10 vehicles are not very fitting. Tier 9 has to utilise 2 unhistorical/fake guns to work on this tier at all and tier 10 is hardly czechoslovak or even a light tank. Still they are in my opinion the best options, should the complete Czechoslovak light line be implemented.

Some vehicles from german and soviet tree reapear, namely the T-15 (with upgrades), Hetzer (upgunned), SU-100 (upgunned).

I've buffed the top speed on some vehicles using either LP or TNH nA chasis, As for LP based ones there was only ever a requirement to achieve at least 55kph and TNH nA did achieve speeds over 70kph during tests even though the official number was 65kph I think.

So that would be the first upgrade to the CS tree - scout line with TNH 57/900 as introductory premium. Generally speaking, these are almost all small tanks with good camo rating, usually great power to weight ratio and in most cases also a good gun depression, but paper armor. Number of them has low caliber autoloaders that would use burst damage instead of single-shot alpha, while their drum reload times are well comparable to single-shot gun reloads thanks to small magazines and low-caliber shells.

The tier 2 Škoda Š-II serves as a gift premium proposal - it is the least shitty of the alternatives and most importantly, it looks most different from all these pre-war Czechoslovak tanks. Besides that one there is a whole bunch of posible tier 2 and 3 premium candidates. After removing TNH nA from the tree, I've added Škoda T12 on tier 3 as alternative gift tank.

Along with the scout line I would also consider adding an alternative low-tier medium line. These tanks aren't particularly special in game terms, but they do carry some historical importance and provide the ability to start playing mediums from tier 2 onwards.

Low tier mediums: The Škoda Š-IIc/T21/22/23M series of prototypes were fairly important, even if they were never mass produced. This tank may have lost the contest for Czechoslovak medium tank to ST vz39, but ended up being much more influential, since it was later produced in Hungary as 40M Turán, thus serving as basis for Turán and Zrínyi series of vehicles. T-III/Š-III were the "heaviest" czechoslovak designs in their time, although both ended up as failure. Some call them heavy, but officially they were medium breakthrough tanks and there is no point in treating them as heavies when you don't have a heavy branch. The Š-III predecessor on tier 2 was the first attempt for "big" czechoslovak tank, with roots in late 1920s. Tatra had one too, but the one from Škoda seems to be better documented. (Kinda sad about switching Š-III for T-III, meaning that the line is no longer "Škoda medium" line, but I'd prefer having a more decent tank there.)

There are many alteranatives for tier 3, but those lack modules for upgrading and generally look same as most other pre-war CS tanks - class III vehicles are the most interesting ones, maybe along with ŠP-IIb - sort of predecessor to the Š-IIc on tier 4 - but it lacks modules for upgrades.

Tier 4 premium to go with this medium minibranch would be the Atypic Tatra tank, which had a very unique construction and could provide interesting gameplay.

Top guns on T-23M is the same 47mm as on ST vz 39 - that is a Wargaming fake to make gun competetive on T4 MT afaik. I'm trying to keep this proposal rather historical (outside radios - I know hardly anything about those), but if WG already did somthing like that, I won't hesitate to use it to solve issues.

Last part was the TD line, added because "I might as well while I'm at it." TD line can be done, but it's a rather problematic one. Using actual existing Czechoslovak stuff one will get to tier 4 with "Hetzer". Throw in some upgunning proposals, wartime and post-war projects, license-produced Soviet tech and I stretched it up to tier 9. And that's it. There was really no need for anything with bigger guns (not counting the artillery). Meaning there was no actual vehicle or project that could become the tier 10 tank destroyer. Afaik. The problem is that if there's no tier 10 TD, Wargaming won't make the line. So SilentStalker came with a bunch of fake proposals for tier 10. In the end I came up with one fake of my own, based on vehicle from 2000s but using the tech from 1970s. Eventually I've dropped that and ended up with a 152mm howitzer varint of tier 9 TD. The howitzer is not very well specified, which makes it well balanceable, especially if we apply the brutal HE damage to it in JP heavy style.

Generally, most of these TDs again work with speed and good RoF. Alpha and pen are so-so, while the armor is no-no. Tiers 3,9,10 have fully traversible turret. Tiers 3,8,9 use autoloaders.

TDs arent particularly my thing anyway, and same could be said about SPGs. SPGs are now also part of the tree - it has it's own issues. There is a limited amount of guns and vehicles, basically I was originally planning to use 240mm and 305mm mortars for tiers 9,10 respectively, but 305mm is just overkill, especially after the arty nerf, so I had to stretch the smaller guns to tier 9. 240mm is not mentioned in most sources I use, which makes it problematic - the one source I am basing this on states that the gun is rifled, however it is not the most reliable source ever... unfortunately there is no proper slef-propelled howitzer between above 15cm, so I had to go with Kominík...
