Global Command and Control System (GCCS) is the United States' armed forces DoD joint command and control (C2) system used to provide accurate, complete, and timely information for the operational chain of command for U.S. armed forces. "GCCS" is most often used to refer to the computer system, but actually consists of hardware, software, common procedures, standards, and numerous applicactions and interfaces that make up an “operational architecture” that provides worldwide connectivity with all levels of command. GCCS incorporates systems that provide situational awareness, support for intelligence, force planning, readiness assessment, and deployment applications that battlefield commanders require to effectively plan and execute joint military operations.


GCCS evolved from earlier predecessors such as TBMCS (Theater Battle Management Core Systems) to fulfill a requirement for technological, procedural, and security improvements to the aging Worldwide Military Command and Control System, aka WWMCCS, and its TEMPEST requirements of Cold War defense from wire tapping and electomagnetic signal interceptions, to include physical (special wire and cabinet shielding, double locks) and operational (special access passes and passwords) measures. On August 30, 1996, DISA officially pulled the plug on WWMCCS and the Joint Staff declared the Global Command and Control System (GCCS) as the joint command and control system of record.[1]

Applications, Functionality

GCCS systems comprise various data processing and web services which are used by many applications supporting combat operations, troop/force movements (JOPES), intelligence analysis and production, targeting, ground weapons and radar analysis, and terrain and weather analysis. Some next generation applications designed for GCCS may support collaboration using chat systems, newsgroups and email. (See JOPES, Mob/ODEE, etc.)

GCCS supports six mission areas (operations, mobilization, deployment, employment, sustainment, and intelligence) through eight functional areas: threat identification and assessment, strategy planning aids, course of action development, execution planning, implementation, monitoring, risk analysis, and a common tactical picture.


GCCS may use NIPRNet, SIPRNet, JWICS, or other IP based networks for connectivity. In some installations, GCCS aggregates over 94 different sources of data.[2]
