lack of units in skirmish

[crash6674]

There is a ton of stuff that you cant get in skirmish mode, why can you not get all the diffrent types of vehicles and people? You are limited to a crappy five types of tanks when there are like two dozen you can get in multiplayer. What the hell. Is there a way to edit in the rest of the units? please help, this is the exact same problem with company of heroes and why I loved this game so much. Better yet can you edit in all the units from all sides to be available to play with?
