Artillery fire support bases of the Freeworld forces played a critical role in the conduct of operations during the Vietnam War. They served to lay down high-volume fire on enemy firing sites, supported friendly infantry operations, and executed harassing fire missions where exact targets were not known. But the firebases themselves - which housed a range of other facilities such as troop shelters, surveillance radars and command centers - had to be defended against ground attack, and as a result became significant fortifications in their own right. This book describes the design, development and operational history of the fire support bases throughout the conflict.
