The Tactical and Technical Fire Control System “ZEUS” is a command and control system which supports Artillery operations, throughout the echelons, from Army Corps to component. It was fully developed by Greek companies and the Artillery School. It can acquire fire data for all the possible combinations of guns and ammunitions, currently at the disposal of the Greek Artillery.
