Sensor Arrays can see any enemy unit within two squares. Data from Sensor Arrays also increases defense readiness: any unit in a land square within two squares of a friendly sensor array gains +25% to its defense.
The ownership of a sensor array is determined by a faction’s borders. If borders move it may come under control of a new faction. If a Sensor Array is not within any faction’s territory the sensor confers a defensive bonus to any faction’s unit within two squares.
