In AFC-42, C3 stands for which trio?

• A. Coordination, Command, and Communications
• B. Control, Command, and Communications
• C. Command, Control, and Communications
• D. Communication, Command, and Control

Answer: (C)

The main idea here is the trio that underpins effective command in maritime operations: Command, Control, and Communications. Command is the authority to make decisions and direct actions. Control is the process of directing and synchronizing those actions to achieve a unified plan. Communications is the reliable exchange of information that connects command decisions to their execution and provides feedback.

In AFC-42, the standard C3 phrase is exactly Command, Control, and Communications. That ordering reflects the flow: the leader has command, that direction is implemented through control, and the whole process is kept coordinated by robust communications. The other options mix in Coordination or swap terms, or put the words in a nonstandard order, which would deviate from the established C3 concept.
