What are operational security (OPSEC) measures designed to protect?

• A. General public information
• B. Sensitive military information
• C. Casual communication
• D. Freely available technology

Answer: (B)

OPSEC is about preventing enemies from learning enough about an operation to undermine it. It targets information tied to military activities—details about plans, capabilities, locations, or vulnerabilities—that, if exposed, could be exploited to harm missions or safety. That’s why protecting sensitive military information is the best fit: it directly reduces the risk that an adversary can infer intentions or weaknesses and act accordingly. General public information, casual chatter, or freely available technology aren’t the specific types of data OPSEC is designed to shield, since they don’t carry the same potential to compromise a mission if disclosed. A practical example is withholding troop movements or sensitive deployment details to avoid tipping off an opponent.
