Thanks for the feedback here everyone one and I just wanted to quickly jump in here and mention that I honestly can't even remember the last time the topic of the Waffen SS has even come up, internally or externally such as a thread like this, when it comes to the Strategic Command series.
I only mention that since as far as I remember the game series has never included Waffen SS units (I had to double check Assault on Communism as that was mentioned above and I don't see them there either) and I believe this was based on a decision probably from about 15 years ago where some felt their inclusion had too much of a negative connotation as Bill alluded to above as well. After that we probably just moved on to the other million and one things that need to get included/done/finished for each game we produce.
Essentially, our only point here is that this was never a recent topic of internal discussion between the development team, development team and Matrix, and/or even in Beta, and that they never at one time existed and were then removed. I really couldn't tell you what German law has to say about them either to be honest.
With this in mind, I hope it paints a picture that this was not something we purposefully did for this game just to upset people one way or the other, as it has always been this way on our end.
Now that being said, part of the reason is simply due to the design and scale of the game where each nation has the same general types, i.e. Divisions, Corps, Army types and so on, with nation specific stats to reflect their differences, and we don't currently include specialized unit types (on a per country basis) that would allow for separate units such as the Waffen SS for the Germans. Again, for the reason for this, you'd have to consider the current scale of the game, and to go back to the early design decision from 15 years ago and the lack of general request for these specific unit types since then in game.
Also, and to confirm, we do include Special Forces units in game, which can be considered Elite units, and as Bill mentioned as well, these can be purchased and renamed as desired and they have their own look and patterns relative to the other units in game. The game can also be fully modded and some creative techniques can be used to add some specific unit types, provided there are enough unused unit type slots in a particular campaign, and we've done this to include Shock units for the Soviets and so on.
Hope this helps,
