Which description correctly defines FPCON Delta?

• A. General threat, unpredictable; measures sustainable indefinitely.
• B. Increased and more predictable threat; sustainable for weeks without undue hardship.
• C. Incident or intel indicates terrorist action likely; creates hardship if sustained.
• D. Immediate area where attack occurred or intel shows imminent attack; localized; not sustained.

Answer: (D)

FPCON Delta is the highest short-term security posture, used when an attack has occurred or there is credible intel that an attack is imminent. The emphasis is on a localized area—the immediate place of the incident or the area under immediate threat—and the heightened security measures are meant to be temporary, not a prolonged condition. Once the threat subsides or has been neutralized, measures can be scaled back.

This is why the description that matches Delta is the one describing an immediate, localized area where an attack has occurred or is imminent, with security actions that are not meant to be sustained. The other descriptions imply broader or longer-lasting conditions that don’t fit Delta’s localized, short-term nature.
