From the Civic Age, each Achaemenid Town Center can permanently choose one specialization: Economic makes nearby Villagers gather 10% faster; Military regenerates nearby troops at 20 hit points per minute and increases their speed by 15%; Defensive adds durability and firepower to the Town Center and boosts nearby units’ attack speed by 15%.

How this system affects decisions
Combat results depend on more than the printed attack number. Compare the attacker’s damage with the target’s armor and armor class, then account for range, reload, accuracy, and any class-specific bonus; a counter bonus is separate from a unit’s ordinary attack. This is why the same unit can trade well into one target and poorly into another.
