Hello.
I know that the topic is coming back like a boomerang, but recently I sat down and analyzed, along with the help of AI and searching the internet (as a confirmation of information from AI), the possibility of adding a Polish technological tree (core) along with a Czech and Slovak subtree, which is a beautiful complement, especially in the middle era. Certainly, the community of these three countries would be very happy, in particular because these communities have been growing rapidly recently.
At the bottom, I send a summary from AI (I didnβt check it so meticulously, so there may be minor errors).
*In the meantime, there were suggestions for development trees that I would rather be able to paste into the comment, because here I was limited by the character limit *
π΅π± π¨πΏ πΈπ° Polish & Czechoslovak Combined Tech Tree (Ground, Aviation & Helicopters)
Executive Summary: All 3 Trees Combined (67% Unique!)
This proposal presents a complete, unified Tech Tree combining Poland as the core nation with Czechoslovakia (Czechia & Slovakia) as a dedicated Sub-Tree across Ground Forces, Aviation, and Helicopters.

π‘οΈ Part 1: Ground Forces Tech Tree (Ranks IβVIII)
1. Ground Concept & Historical Justification
This proposal presents a complete, 5-line Ground Forces Tech Tree combining Poland as the core nation (Lines 1β4) with Czechoslovakia / Czechia & Slovakia as a dedicated Sub-Tree (Line 5 + SPAA/Support integration).
Why do these three nations complement each other so well?
- Ranks VβVIII (Cold War & Modern Era) β Polish Core Dominance: Poland fields a massive number of unique indigenous designs, radical 1990s prototypes, and deep local modernizations. This includes the PT-91 Twardy family (PT-91, PT-91M Pendekar, PT-16), the wheeled KTO Rosomak family (Hitfist-30P, unmanned ZSSW-30 with Spike-LR, WWO Wilk 105/120mm), tracked IFVs (BWP Borsuk, WPB Anders, BWP-2000, BWP-40), indigenous SPH/mortars (AHS Krab, M120K Rak), and indigenous SPAA (PZA Loara, SPZR Poprad, Pilica, MaΕa Narew).
- Ranks IIβIV (WWII & 1950s) β Czechoslovak Industry Eliminates the βCopy-Paste Gapβ: Because Poland was occupied during WWII, a standalone Polish tree would rely heavily on Allied and Soviet copy-paste vehicles in Ranks IIβIII. Integrating Czechoslovakia solves this completely: pre-war and post-war Czechoslovak armor (LT vz. 35, LT vz. 38, ST vz. 39, Ε koda T-25, TVP T 50/51, LP-152, T-34/100) fills the mid-tiers with unique designs, while adding iconic high-tier vehicles like the T-72M2 Moderna, T-72M4CZ, vz. 77 Dana, ShKH Zuzana 2, and CV9030CZ Mk.IV.
2. Ground Uniqueness vs. Copy-Paste Breakdown (74% Unique!)
A common concern with new tech trees is the amount of βCopy-Pasteβ (C&P) vehicles. Below is the exact mathematical breakdown of all 123 researchable vehicles in the main tree (plus 22 Premium/Event/Squadron vehicles):
- Total Researchable Vehicles (Main Tree): 123
- Unique Indigenous Designs, Prototypes & Deep Local Modernizations: 91 vehicles (74.0%)
- Indigenous CZ/PL Vehicles / License Builds already present in other WT trees (
π): 6 vehicles (4.9%) β LT vz. 35, LT vz. 38, ST-I (Hetzer), SD-100, Praga vz. 53/59 JeΕ‘tΔrka, 2S1 GoΕΊdzik. - Pure Foreign Copy-Paste (
π): 26 vehicles (21.1%) β concentrated mainly in Ranks IIβIII (historical WWII Polish Armed Forces in the West/East: Shermans, Cromwells, Achilles, T-34-76, IS-2m), a few Cold War Warsaw Pact bridge vehicles (T-55A, BWP-1, T-72M1), and 4 modern off-the-shelf imports (Leopard 2A4, K9A1, K2GF, M1A2 SEPv3).
- Zero Copy-Paste in Rank VI: 100% (15 out of 15) of Rank VI vehicles are unique to Poland, Czechia, and Slovakia!
- Grand Total (Including 22 Premium/Event/Squadron vehicles): 145 vehicles β 106 Unique/Modified (73.1%) vs. 39 Copy-Paste/In-Game (
π- 26.9%).
4. Key Highlights of Unique Ground Vehicles
- PT-91 Family (PT-91 Twardy / PT-91M Pendekar / PT-16): Indigenous Polish ERAWA-1/2 explosive reactive armor (minimal gaps), Drawa-T/Sagem thermal FCS, Obra-3 laser warning receiver, and in the Pendekar β a 1,000 hp S-1000R engine paired with a Renk automatic transmission offering fast reverse speed. PT-16 upgrades this further with a 120mm smoothbore gun and heavy modular composite armor.
- KTO Rosomak & BWP Borsuk (ZSSW-30): Equipped with the Polish unmanned ZSSW-30 turret featuring a 30mm Bushmaster II cannon and twin Spike-LR fire-and-forget / man-in-the-loop ATGMs.
- T-72M2 Moderna & T-72M4CZ: Iconic Slovak and Czech modernizations. Moderna features DYNAS ERA and a roof-mounted 30mm 2A42 autocannon, while T-72M4CZ boasts a 1,000 hp Perkins engine, automatic transmission, and TURMS-T fire control system.
- PZA Loara & SPZR Poprad: Loara is a Polish twin-35mm Oerlikon KDA radar SPAA mounted on a PT-91 hull with dual search/track radars and AHEAD programmable ammunition. Poprad brings 4x indigenous Polish Piorun MANPADS with high flare resistance.
βοΈ Part 2: Aviation Tech Tree (Ranks IβVIII)
5. Aviation Concept & Historical Justification
Just like the Ground Forces tree, combining Poland and Czechoslovakia (Czechia & Slovakia) creates a remarkably self-sufficient Aviation Tech Tree across all 8 Ranks:
- Ranks IβII (Interwar & 1939): Both Poland (PZL, PWS, LWS, Lublin) and Czechoslovakia (Avia, Letov, Aero) were European aviation powerhouses in the 1930s. From the iconic gull-wing PZL P.11c, PZL P.24, and PZL.37 ΕoΕ to the Avia B-534, Avia B-35/B-135, and pre-war prototypes like the PZL.50 JastrzΔ b and PZL.38 Wilk, the low tiers are nearly 100% unique.
- Ranks IIIβIV (WWII in Exile): Represents the legendary Polish Air Force in Great Britain (No. 303 βKoΕciuszkoβ Squadron, Skalskiβs Circus, etc.), Polish Aviation on the Eastern Front (1. PLM βWarszawaβ), Czechoslovak RAF squadrons (No. 310, 311, 312, 313), and post-war transitional designs like the Avia S-199, Avia B-33, and armed TS-8 Bies.
- Ranks VβVIII (Cold War & Modern Era): Unlike minor trees that rely purely on Soviet or American exports, Poland and Czechoslovakia built their own jet trainers, light attack aircraft, and heavily modified strike fighters: TS-11 Iskra, PZL I-22 Iryda, PZL-230F Skorpion, Lim-5M / Lim-6bis (unique Polish twin-wheel, drag-chute & RATO CAS modifications of the MiG-17), Aero L-29 DelfΓn, L-39ZA Albatros, L-159A ALCA, L-39NG Skyfox, and modern multirole platforms (FA-50GF/PL, F-16C/D/V JastrzΔ b, MiG-29AS, JAS39C MS20, and F-35A Husarz).
6. Aviation Uniqueness vs. Copy-Paste Breakdown (58% Unique!)
- Total Researchable Aircraft (Main Tree): 116
- Unique Indigenous Designs, Prototypes & Local Modifications: 67 aircraft (57.8%)
- Foreign Copy-Paste / In-Game Equivalents (
π): 49 aircraft (42.2%) β heavily concentrated in Ranks IIIβIV (historical WWII RAF and Soviet aircraft flown by Polish and Czechoslovak aces).
- Ranks I & II are 84.4% Unique: 27 out of 32 aircraft in the first two ranks are completely indigenous Polish and Czechoslovak designs!
- Rank V is 83.3% Unique: 15 out of 18 early jets are indigenous or heavily modified local variants (TS-11 family, Lim-1/5/6M family, Avia S-92, Aero L-29/L-39).
- Grand Total (Including 20 Premium/Event/Squadron aircraft): 136 aircraft β 81 Unique/Modified (59.6%) vs. 55 Copy-Paste/In-Game (
π- 40.4%).
π Part 3: Helicopter Tech Tree (Ranks VβVII)
8. Helicopter Concept & Uniqueness Breakdown (68% Unique!)
Poland is one of the very few nations in the world with a complete indigenous helicopter industry (PZL-Εwidnik and PZL-Mielec). Notably, every single Mi-2 in history was manufactured in Poland, alongside the completely indigenous PZL W-3 SokΓ³Ε / GΕuszec family and the SW-4 Puszczyk.
- Total Researchable Helicopters (Main Tree): 19
- Unique Indigenous Designs & Deep Local Modernizations: 13 helicopters (68.4%)
- Foreign Copy-Paste / In-Game Equivalents (
π): 6 helicopters (31.6%) β Mi-24D, Mi-24V/W, AH-1Z Viper, AH-64E Apache Guardian.
- Grand Total (Including 4 Premium/Event/Squadron helicopters): 23 helicopters β 16 Unique/Modified (69.6%) vs. 7 Copy-Paste (
π- 30.4%).
10. Key Highlights of Unique Aircraft & Helicopters
- PZL.37B ΕoΕ & PZL.50 JastrzΔ b: The ΕoΕ (βElkβ) was one of the most advanced medium bombers of 1939, capable of carrying a massive 2,580 kg bomb load (more than an early He 111) in a sleek, twin-tail laminar-wing airframe. The JastrzΔ b and Wilk provide fast, well-armed low-tier indigenous fighters.
- Lim-5M & Lim-6bis: Polish ground-attack evolutions of the MiG-17 manufactured by WSK-Mielec. They feature twin-wheel main landing gear for rough-field operations, drag chutes at the base of the rudder, RATO (Rocket-Assisted Take-Off) boosters, and additional underwing pylons for Mars-2 rocket pods and bombs.
- TS-11 Iskra & PZL I-22 Iryda M-96: Indigenous Polish jet trainers/light attackers armed with 23mm cannons (NS-23 / GSz-23Ε), rocket pods, bombs, and R-60MK air-to-air missiles on the Iryda.
- Aero L-159A ALCA & L-39NG Skyfox: Czech single-seat and twin-seat light combat aircraft equipped with NATO avionics, FIAR Grifo-L pulse-doppler radar, 20mm Plamen cannon pods, AGM-65 Maverick ATGMs, GBU-12 Paveway II laser-guided bombs, and AIM-9M Sidewinders.
- PZL W-3U Salamandra, W-3PL GΕuszec & W-3WB Huzar: Indigenous Polish twin-engine helicopters built by PZL-Εwidnik. The W-3U carries a twin 23mm GSz-23Ε cannon and up to 8x supersonic 9M114 Szturm ATGMs, while the W-3WB Huzar prototype integrates South African Kentron ZT35 Ingwe laser beam-riding tandem ATGMs and a nose-mounted 20mm GA-1 cannon.
