Joint Communications System: Joint Publication 6-0

The objective of the joint communications system is to assist the joint force commander (JFC) in command and control (C2) of military operations. While C2 alone will neither destroy an adversary target nor accomplish emergency resupply, no single activity in military operations is more important. The first element of C2 system is people — people who acquire information, make decisions, take action, communicate, and collaborate with one another to accomplish a common goal. The second element of the C2 system taken collectively are the facilities, equipment, communications, and procedures essential to a commander for planning, directing, and controlling operations of assigned forces pursuant to the missions assigned. Although families of hardware are often referred to as “systems,” the C2 system is more than simply equipment. High-quality equipment and advanced technology do not guarantee effective C2. Effective C2 starts with well-trained and qualified people and an effective guiding philosophy and procedures.
