Which DEFCON level indicates a heightened state of readiness just below maximum?

DEFCON 2 represents a heightened state of readiness just below maximum. This level indicates that the armed forces are prepared to respond to an imminent threat, with readiness heightened beyond normal peacetime operations. At this stage, military units are positioned and prepared to carry out their mission but have not yet been fully mobilized, which would occur at DEFCON 1.

DEFCON levels are a series of escalating conditions that represent the defense readiness condition of the U.S. Armed Forces. DEFCON 1 is the maximum readiness situation, primarily indicating that nuclear war is imminent and all forces are on full alert. DEFCON 3 suggests an increase in readiness and capability, while DEFCON 4 indicates a state of normal readiness, so DEFCON 2 accurately captures that heightened but not maximum state. Understanding the significance of each DEFCON level is crucial for grasping military readiness in response to potential threats.
