Merci PDF,
I hope that you will have the same good feelings toward me once your beloved veteran core force units become trapped by an AI encircle maneuver...
Here is the first hint of the campaign: During your first boost for core points I strongly advise you to buy a section of 6 in (on-map) artillery guns along with a section of ammo trucks.
Here is the second hint of the campaign: Use scouts and set their reaction range to 1.
These units might save you from some very unpleasant surprises.
cheers,
Pyros
