Creating rebel stacks

[Dutchhoplite]

Hi all :)

How do I create rebel units (a smal stack) outside a city using console commands? What do I have to type in?

I'm preparing my KH campaign and i want to know if it's possible to create an Athenian or Spartan army this way and simulating my little "civil war".

I know it could be done trough multiplayer but i'm wondering if the above is a possibility.

Thanks
