Game Features Task Forces Task Forces are a collection of units that have been grouped together to represent an army of units. The Task Force takes the movement of the slowest unit, but groups together the strengths of all of the units. Power Rings Power Rings are the circles that surround the units in the map window; the colour defines which civilization/culture they belong to, while the Area of the circle indicates the strength. There are two rings, the outer ring shows the strength of all of the units/task forces in the square, while the inner ring is the individual unit/task forces strength. If there is a power ring in a square, but there is no unit, this is because it is a culture's square.
