What characterizes DEFCON 4?

DEFCON 4 is characterized by a state of normal readiness with heightened intelligence and enhanced security measures. This level indicates that while there is no immediate threat, the military is aware of potential developments that could affect national security. Increased intelligence gathering and strengthened security protocols are implemented to prepare for a possible escalation in threats.

In this state, military personnel are not mobilized for immediate action but remain vigilant, monitoring situations and gathering data to ensure readiness should conditions change. This concept is crucial, as it differentiates DEFCON 4 from other levels, where readiness and military mobilization may be more pronounced.
