There is good terrain and bad terrain. There are grounds to attack and to attack from. This manual is written from the vantage point of a challenger attacking a leader. As a starter, challengers in the exploratory quadrant are in a good position to attack leaders in the expeditionary quadrant. Attacks by challengers on leaders in the provisionary quadrant are not likely to result in a productive gain unless part of a larger ambition. There are cases where challengers in the mercenary quadrant can attack a leader in the expeditionary quadrant as a means to revitalize a dying business or jump start a new entry.
