Command and Control (C2) is simple to] describe but hard to execute. There are only two necessary tasks to fully realize command and control - see the battlefield to make a decision and disseminate actions required to make the decision happen. All other activities, roles and functions flow from this basic concept. This paper examines the requirement to C2 the network and associated personnel, facilities, and resources at the Regional Combatant Commander (RCC) level. This paper will not address the Functional Combatant Commanders (FCC) due to the fact they generally have assigned forces that operate on a global basis and are habitually assigned. The RCC may have forces that are habitually assigned but the Global War on Terrorism has demonstrated that all of the United States Military Forces must be expeditionary and the mission will dictate the forces used in the operation.
