do not specify well,there are many different models of aircraft models and the battle tanks,i am sure that among which panzer III and IV are missing, I speak of their variants of letters
Ok, so variants are missing. As the last 2 posters said, those are decisions about where to stop the complexities of the game. Every time a new AFV model is introduced, it implies many things, including how it is produced, where, the upgrade path, dates of replacement. So where they stop adding details is somewhere along the line of code and data management coupled with playability. Of course, such high level of details is fun for the players more on the geek side and micromanagement... but doesn't bring much to those who like to push counters and don't care too much about the details.
I guess it's all a question of balance between the 2.
For the armaments images and representations, have you tried "Jison's map mods"? It has some really nice improvements on the original WitE maps and unit display graphics.
