Which statement best describes a PL-4 resource?

• A. A resource that is used only for routine maintenance
• B. The loss, theft, misuse, compromise or destruction adversely affect the war mission capability
• C. A resource whose compromise has a significant impact on wartime mission capability
• D. A non-essential asset with no effect on operations

Answer: (B)

Protection Level 4 resources are assets whose compromise can adversely affect mission capability, even if the damage isn’t catastrophic. They’re not the absolute most critical items, but they’re important enough that loss, theft, misuse, or destruction would hinder wartime operations or readiness. That’s why the best description is that their compromise would adversely affect the war mission capability — it accurately conveys a negative impact on operations without implying complete or nationwide failure. The other ideas miss the point: some assets aren’t limited to routine maintenance, and labeling something as non-essential with no effect on operations isn’t accurate for PL-4. Others imply a higher level of impact, which would correspond to a more protective category than PL-4.
