Red Army = most effective force !

[Nightblade]

If you buy yourself the units/equipment the AI will use against your army, you can easily solve this problem and then create a possible "to win" or "to lose" battle according to the armies setup you decide.

This way, sf or other kind of very expensive units can be very well used in generated battles without a problem and prevent the frustration such 100 vs 1 situation usually lead into when the AI buy very cheap units in nearly invicincible amount.
