Which item is NOT typically considered a core line of operation for information operations in joint doctrine?

• A. Mine warfare.
• B. Public affairs.
• C. Operations Security.
• D. Military Deception.

Answer: (B)

The key idea is how information operations are organized to shape the adversary’s information environment. Information operations focus on activities that influence, deceive, or protect information flows to affect decisions and actions of others. Public affairs, while important and often supporting IO, is a separate function whose purpose is to communicate officially with the public and internal audiences, manage credibility, and provide factual information. It isn’t counted as a core line of operation within information operations itself, because it doesn’t aim to manipulate the enemy’s perceptions or deny them information in pursuit of a military objective. That separation is why public affairs is the best choice for what is NOT a core line of operation in joint IO. The other options reflect IO activities (such as deception and protecting sensitive information) or, in some contexts, domains closely tied to IO objectives, whereas public affairs sits outside the core IO lines.
