The Pillar is a heavy and robust unit, perfect for defense or assault. Its shells travel in an arc that allows it to fire over concrete or minor elevation changes. Because of low mobility, you should always move Pillars in close formation to concentrate their firepower. A mixed group of Pillars and Parashields is an especially dangerous formation. The Pillars are strong enough to act as mobile point defense units, while their low speed and close formation allows the Parashields to perfectly defend them, in one solid wall formation, much like a point defense creep. Any unit coming in range will not only immediately take fire from all pillars in the formation simultaneously, it will also have to break through several close formation shields to inflict any damage at all.
