Which statement best defines the core components of C2 architecture?

• A. Hardware, software, and data storage only.
• B. Physical security, communications, and logistics.
• C. Policies, budgets, and audits.
• D. People, procedures, and technologies enabling command decisions, information flow, and control actions across the networked environment.

Answer: (D)

Understanding C2 architecture centers on how people, procedures, and technologies come together to enable command decisions, information flow, and control actions across a networked environment. The best statement captures this tripod: people who make and authorize decisions, procedures that standardize how information is processed and actions are taken, and technologies that provide the tools and networks to move data and execute commands. Together, these elements address not just what is used, but who uses it, how decisions are made, and how those decisions translate into coordinated actions across the system.

The other options miss one or more essential dimensions. Hardware, software, and data storage describe the components of systems but fail to include the human and procedural aspects that drive how those components are used in real operations. Physical security, communications, and logistics cover protective and support functions rather than the decision-making and control framework itself. Policies, budgets, and audits concern governance and oversight rather than the day-to-day architecture that enables command decisions and networked information flow.

So, the emphasis on people, procedures, and technologies enabling command decisions, information flow, and control actions across the networked environment best defines C2 architecture.
