What is indicated by DEFCON 4?

DEFCON 4 indicates a state of increased intelligence and security measures. In this readiness level, the military is on watch and actively enhancing its security posture. It reflects a situation where tensions might be rising, but the country is not yet on a heightened military alert that would be indicated by higher DEFCON levels.

While the other readiness states communicated by DEFCON levels express varying degrees of alert, DEFCON 4 specifically emphasizes a proactive approach to security, allowing the military to gather intelligence and prepare for potential threats without being engaged in an immediate response scenario. This level serves to increase situational awareness among military personnel and organizations, ensuring they are prepared should conditions deteriorate.
