What statement correctly describes the relationship between nodes and communications in a C2 network?

• A. Nodes are command centers, units, or devices, and communications are the networks that connect them to exchange data and orders.
• B. Nodes perform data analysis; communications store data.
• C. Nodes are physical locations only; communications are theoretical.
• D. Nodes are only satellites; communications are radio waves.

Answer: (C)

In a C2 network, nodes are the command centers, units, or devices that perform or relay decision-making and actions, while communications are the networks and channels that link those nodes together to exchange data and orders. The strength of the system comes from robust communications that keep information flowing between all nodes—up and down the chain, and across domains—so commands, situational updates, and feedback reach the right places in time.

This matters because reducing nodes to locations only misses that a node can be a capable processing or transmission element, not just a fixed point. Treating communications as storage mischaracterizes them as a repository rather than the path that moves information. And limiting nodes to satellites is too narrow since ground, air, and maritime nodes all participate, using multiple media beyond just radio waves.
