A Hungarian ground forces subtree was added to the Italian tech tree in the "Sons of Attila" update. This is my improved version of the Hungarian ground forces subtree, featuring many more unique Hungarian vehicles and less copy-paste ones.
Note: 🞧 is the symbol for the Hungarian WW2 roundel which should appear as a white cross/plus on a black square, but this symbol only appears as it should in-game, so it appears as just a white cross here, but this represents a Hungarian WW2 roundel. ◔ is the symbol for the Hungarian cold war and modern era roundel which should appear as the modern Hungarian Air Force/Ground Forces roundel.
The battle pass/event reward Hungarian vehicles already in-game are the premium Toldi IIA (battle pass reward), premium Turan II (battle pass reward), and the premium Zrinyi I (event vehicle). These would remain mostly the same in my improved subtree proposal, but with a few changes. The Toldi IIA and the Turan II would be renamed to the Toldi IIA (2nd Armoured Division) and the Turán II (2nd Armoured Division) respectively - this is so that a Toldi IIA and a Turán II can be added into the researchable tech tree. The researchable and battle pass premium versions would differ by name and the premium versions would come with premium benifits, as well as a unique camoflague/insignia of the 2nd Armoured Division. The researchable Turán II could also not be given the side skirts that the battle pass version gets. This way, everyone who got these premium battle pass versions still gets to keep a somewhat unique premium vehicle, while these iconic and essential Hungarian vehicles will also appear in the researchable tree. It is already common in War Thunder to have a premium version of a researchable vehicle but belonging to a certain division or unit with a special camo, so I think this solution is perfect for these two tanks. As for the Zrinyi I, the solution is even more simple; since the Zrinyi I was never meant to have rockets and they were mounted experimentally for testing, the solution is obviously to add a researchable Zrinyi I but without the rockets. This way, the Zrinyi I in its proper form (without rockets) is the standard researchable version essential to the subtree, and the experimental version with rockets mounted is the premium version from the event. Players who earned the premium Zrinyi I can still enjoy the premium perks over the standard subtree Zrinyi I, as well as have the unique rockets. All that would need to change is the name of the current premium Zrinyi I to Zrínyi I Sorozatvető (Zrinyi I multiple rocket launcher), and the rocket launchers' firing angle should be changed too - the rockets should be able to be fired at 0 degrees straight forwards horizontally, as shown in the picture of the rockets on the Zrinyi I. This (as well as possibly more buffs to help the rockets be more useful on the Zrinyi I), would make the rockets on the premium Zrinyi I actually useable, worth having, and a proper distinguishing gameplay mechanic between the standard and premium Zrinyi I.
The Toldi II Buzogányvető can be used in the researchable tree if needed, or can come as a premium if needed, it is there just to show that it's an available option. Some copy-paste vehicles in the tech tree (e.g. Párduc) can also be removed if needed/deemed unnecessary. While I have included all of the most well known and important Hungarian vehicles, I have not included every vehicle that Hungary could get, so there are more that can be added later if needed.
For the more obscure vehicles in this tree such as the Opel Blitz 39.M Gebauer, Csepel D-344 KPVT, Toldi II Buzogányvető, T-55A SZRP, T-72M CURRUS, BMP-1 OWS-25 CURRUS, etc. contact atta26hu for more information on them as information for these vehicles is a bit hard to find and he knows more about them, I only have a vague understanding of these vehicles. Some of these are still easy to add/model in War Thunder though, as they combine a relatively well known hull/truck with a relatively well known weapon system.
Not all Turán tanks/Zrínyi tank destroyers of the same type were identical. For example, an early and a late Turán I/Turán II/Zrínyi II would have had a few differences between them including the use of side skirts (spaced armour), spare track armour and some had different armour thicknesses due to extra armour plates being rivetted on or the existing armour plates being made thicker. Sufficiently differing versions of these tanks can be added as new vehicles to bolster the tree if needed, or be added as premium/event vehicles. For example, a late Zrínyi II with 25 mm thicker armour and side skirts could be added as the Zrínyi II (1944) at 3.0 maybe. This could also be used to differentiate more between the battle pass Toldi IIA/Turán II and the researchable Toldi IIA/Turán II.
