Overview

ATCIS is the Republic of Korea Army's digitized command-information backbone, distributing common operational picture, orders and fire-support data across corps-to-battalion echelons as part of Korea's long-running network-centric warfare modernization. Hanwha Systems and other Korean defense-electronics firms have supplied major C2 and networking subsystems supporting ATCIS and its successor programs; as with many non-Western C2 systems, detailed technical specifications are not fully public and program details should be treated as based on manufacturer and government disclosures.
