# Zones of Influence

Combat units exert a ZOI out to a range of 3 hexes and artillery exerts a ZOI out to 5 hexes.  The ZOI does not affect hexes that are not in the unit’s LOS; a unit cannot “influence” what it cannot see.  A ZOI can be blocked by terrain such as town hexes, woods, and higher intervening elevations.  Units, friendly or enemy, do not block a ZOI.

The ZOI affects enemy road movement, reorganization, recovery, and construction.

To see the enemies' ZOI, select the ZOI Button
