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.
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.
Mobility is bad and the superstructure somewhat thin, but main glacis may bounce stuff.

1946 Proposal from Škoda to mount German 15cm sFH 18 on T-22 chasis. The project was rejected as outdated. Similiar versions with 10.5cm leFH 18 guns also existed.
T-22 is improved T-21, single prototype without turret was made. The project was further developed into T-23M.
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.
Top gun is Hummel gun, so it should do rather well on tier 5. No gun depression though.
Self-proppeled howitzer on T-25 chasis was a project from 1942. Wooden mockup for at least the 10.5cm version existed.

Wartime project by Škoda Werke for self-propelled howitzer based on T-25 chasis, blueprint dated to 1942. Turreted. 105mm versiion also existed.
Radios - no idea as usual, copied from T-25. Side armor numbers are just me guessing. I assume 360 rotation in the turret.
Rather tall, but turreted, with 5 degrees of gun depression and decent mobility. Kinda like the french one.

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

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.
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.
Historical. Radios taken from German Panther. Turret armor - unknown levels of paper.
Same guns as previous vehicle, but with a 360 turret and armor on chasis. Lacks gun depression.
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.

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.
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.
Armor values unknown, but it should handle stuff like HMGs. Not sure about the armor thickness but the rest is fine.
Note that first 2 prototypes used a T-813 chasis instead of T-815. I've never seen any photos though.
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.
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.
Also note that the turret apparently can't go full 360°, only 225 to each side.

Project of 7.5cm self-propelled anti-tank gun on T-21(22/23M) chasis designed in 1941, probably on Wermacht request, for export to allied nations. Only wooden model was built.
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.
Engines are taken from various T-21/22/23M prtotypes. Radio is guesswork.
Similiar to tier 4 StuG. Bigger target, but better gun depression and RoF.
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.

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.
None of the guns were ever mounted on the ST-I, it normally used the usual JgPz38(t) 75mm guns.
Engines: Historical Jagdpanzer 38(t) engine would be Praga AE at 160hp. The stock one here was used on Starr series. Last engine was used on Kätzchen prototypes - recon vehicle / APC also based on the TNH nA chasis.
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.
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.

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.
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.
There were also turreted variants of thse vehicles with same armanent and less armor - I'm using those as light tanks.
Kinda like the previous TD, but faster, with much improved gun handling. Not quite the pew-pew of E25 though.

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.
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 other in-game TVP vehicles, not historical.
There were also turreted variants of the vehicle with same armanent and less armor - that is basically the tier 9 TD.
Decent camo, nice gun, shit armor, pretty fast.

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.
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.
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 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.
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.
Added the 130mm R14 gun as an option to possibly keep the gameplay style from previous tier.

With the 2.0 changes balancing of Škoda T 21 seems a tad problematic. Realism is out of the windows as well, judging by the massive buffs to guns and engines on lower tiers. That said I kinda wanted to preserve the vehicle, so there we go: T-21 config with unique gun that served as the prototype for Turán. Engine to be buffed accordingly. Not sure about the radio rn.

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.
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.
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.
In reality a T 12 turret (enlarged LT vz 35 turret) was used to mount the bigger guns.
Look, after 2.0 especially these texts are outdated. I should probably just delete them altogether.

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.

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 overal considered the project to be better than Soviet PT-76. Regardless, the project was scrapped in 1956.
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 allow for better gun depression.
The exact 57mm gun is unknown. The A25 gun is a (here buffed) existing project indented to be mounted on tanks (TNH 57/900), while the second option is a tank gun developed from R10 AA cannon hypothetised by one of the sources (performance data here completely fictional).
Radio is guesswork, rest should be historical.
With the R10 gun this would effectively be the tier 9 Šelma except missing one gun barrel, thus halved RoF, faster reload, possibly less bloom, giving it rather unique playstyle.
With the A25 gun it would be more of a classic autloader like the French Project Louis.
Imo each option is viable and since there are two hull designes from Leták, both could be implemented as their own vehicle.
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.

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.
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.
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.
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.
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. A technology demonstrator based off one of the TNH nA prototypes existed.

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.
Original proposal uses the stock engine and expect 48kph as desired speed. The top engine corresponds to an engine setup from TNH-based Katzchen APC project. Top speed increased at be at least close to in-game T17.
After 2.0 both max speed and engine performance are mere balancing numbers, so, buff as required.
More of a fast and stealthy medium with somewhat lacking mobility for a light tank, but decent armor, light tank camo bonus and decent burst potential. Probably something of a surprise brawler.
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.

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.
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.
While some were used as small fortifications in Slovakia, the vehicles never really saw combat and were eventually scrapped.
In 1937 manufacturer proposed an upgrade for LT vz. 34. This included improved suspension, new engine and gun and extra frontal armor. LT vz. 34 prototype was rebuild to this standard to be trialed along the TNH tank. While the P-II-R did not win the competition for what became the LT vz. 38, it was planned to convert the existing vz.34 vehicles to this standard as a way to aquire up-to-date vehicles on the cheap. This however did not take place before the German occupation.
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).
To combat the low performance, I've added the upgrades from the R prototype, however do note that information on the R variant is scarce and likely not considered reliable by many.
Known designations: P-II (prototype/company designation); LT vz. 34 (army designation).
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).
P-II-R uprades also include 25mm prontal hull armor and corresponding p2w ratio upgrade to 16hp/t.

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.

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, no prototypes were ever built.

In 1938 patent was awarded to Tatra for this tank conception.
Pretty historical, maybe except the radio.
The tank isn't very fast, but it's not slow either and would have very good p2w ratio for a heavy/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.
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).
Small gun in tall turret means potentially very good gun depression (dependent on balancing). 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 smaller stuff, especially if angled.
Tatra prototype for a breakthrough tank requested by Czechoslovak army. Development started in 1932 in form of KÚV project. The army changed their requirements in 1934 for purely tracked vehicle and since 1936 Tatra prototypes were tested along with prototpes from Škoda. In the end both Škoda and Tatra prototypes were considered failure and the breakthrough tank project was cancelled. Two prototypes were made.

This tank is already in Russian/Lesta WoT client as a tier 4 premium with an overbuffed gun. Swapped for the historical one, fixed the engine power. Overal I think this vehicle belongs to tier 3.
Projects for light, turreted tank destroyer/SPG. Concept from 1948, no vehicles were built. Tank destroyer variant used 76.2mm gun, while howitzer variant used 105mm.

SPG project based on LP platform propesed by Škoda - intended as mobile light turreted tank destroyer. Concept vehicle based on Ministry of National Defense requests from 1948. Never got to development as the LP chasis project was dropped.
Pretty much as intended.
More or less a smaller version of the ShPTK-TVP 100.

A combination of Tiger-related projects by Škoda. One is a project for a turret with 10,5cm gun (1941), the other is the alleged use of Tiger as a testbed for A18 75mm gun. (1947)

A mix of Tiger related modifications by Škoda.
Firstly a Tiger allegedly being used as a testbed for A18 75mm autoloading canon in 1947.
Second, a turred designed for use on Tiger on request of Porsche in 1941, using 10,5 cm Škoda gun.
For one, the second turret and gun were intended for Porsche Tiger and whether or not it would fit the Henshel Tiger is a question, although it probably should. As for the A18 testbed story, I've only ever seen it as a side mention to other topics tbh.
The 10,5 cm gun could be a further development of 10,5cm Škoda J1 (vz.35) gun for tank use, though that's more of a speculation.
Stock gun is A18 provides good gun handling and dpm for less pen/alpha, top gun provides big alpha for less dpm/accuracy.
Further development of Škoda T 15.

About the proposal
This tree proposal is no longer maintained.
I didn't really actively play the game during the last update of this tree and now that WG has anounced another fake Czechoslovak tank - a heavy one nonetheless, implying a later introduction of a fake heavy line - I'm just done with this.
Seems like I'm back for the time being. WoT may be worse than ever in 2024, but at least it's not War Thunder. Occasional updates may happen.
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
Other trees built on this template
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.
January 2026
- Added autocanon option to Leták.
October 2025
- Updated Škoda T15A according to the supertest data, removed Škoda T16 for created lack of gun options.
September 2025
- Updated tank stats from WoT 2.0 update.
- Updated the proposals accordingly (Engines may or may not be buffed accordingly to 2.0.)
- Removed Škoda T21, introduced Škoda T-21/40 as tier 4 premium instead.
- Removed Škoda T15 as WG is introducing the Škoda T15A premium.
- I haven't really been playing since start of 2025 and after 2.0 I can certainly say I am losing touch with what is going on with the game. Guns and engines performance is being totally overbuffed on lower tiers. I suppose it is a way to finally balance out the premiums, but the numbers now have little to do with reality, so trying to have a tree proposal with some emphasis on realism now seems more pointless than ever. I'll probably stop updating the tanks descriptions, it does get tiresome for what it is.
December 2024
- Intorducing DANA Prototype, pushing other SPGs a tier lower, removing the T22 SPG.
August 2024
- Reworked the LT line in accordance with 1.26 update. That includes turning TNH 57/900 into tech tree vehicle to fill up the gap at tier 6, turning Leták to tier 7 premium vehicle instead and turinig the turreted TD on LP chasis into tier 6 premium TD. Also removed a radio or two somewhere.
- Added LT vz. 34 R alternative modules to LT vz. 34 premium.
- Removed full-fake premium tanks as tier 8 was starting to take up too much vertical space for that crap.
June 2024
- Added a tier 6 heavy to the tree. Added the rest of fake heavy branch into overview, but won't do details on them.
- Changed Tatra Atypical Tank into a heavy.
May 2024
- Added new ingame premiums (ShPTK-TVP 100, Panzerwagen 39), including Tatra T-III (though I really naively hope WG puts it to tier 3)
- Moved Atypic Tatra Tank to tier 4 in reaction to Tatra-III.
- Removed some stock modules on some vehicles for less painful stock grind.
- Will *NOT* add the fake heavy line. I might add the fake light line since the current propsal is kinda wonky when it comes to top tiers, but we'll see about that.
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...
