I think there should be some maps featuring Hungarian forces. For example: Some of the early stages of Operation Barbarossa, Battle of Debrecen, maybe Operation Panzerfaust. They could also have tanks and armored vehicles, such as Toldi I Light tank, Turan I Medium tank, German tanks with Hungarian markings.
For armored vehicles: Botond Armored Jeep (transport), 39M Csaba (armed with a 20mm machine gun). Hungarian aircrafts would be German fighters and bombers.
Artillery and Anti-tank weapons are also available, for example: Zrinyi Self propelled artillery gun, M1940 40mm anti-tank gun and the 44M Macethrower (A weapon invented by Hungarian engineers. Armed with 2 panzerfausts.) Anti-air weapons and vehicles could be the Hungarian Nimrod. (Armed with a 40mm Bofors.)
I know modding, modelling and map creating can be difficult, but I think it would be a nice touch, to have the Hungarian army in the game. ( I can also give more information about the Hungarian army.)
