Pin-point Barrier Defense System, also known as Pin-point Barrier System, was a mobile micro-shield system created from energy remaining from the fold drive. It required several operators to function, using a special trackball control system. It was developed by Dr. Emil Lang of the Robotech Research Group. A more advanced version, the Omni-directional Barrier, was later developed. It enveloped the entire ship, but overloaded if put under too much stress from enemy fire. It would later be used for more advanced Robotech ships under the United Earth Forces and Robotech Expeditionary Forces.
