In an OPORD, which paragraph is primarily concerned with command relationships and signaling information?

• A. Execution
• B. Command and Signal
• C. Mission
• D. Situation

Answer: (B)

In an OPORD, the paragraph that handles command relationships and signaling information is the one that lays out who commands whom, the chain of command, locations of command posts, and the plan for communications. It includes the signal plan—call signs, frequencies, authentication, and timing—so units know who to contact and how to stay coordinated during the operation. The other sections cover different facets: the Situation explains the environment and forces, the Mission states the task to be accomplished, and the Execution describes how the mission will be carried out. Because this paragraph combines both who leads whom and how everyone stays connected, it is the correct choice.
