Alert state

For the American hardcore punk group, see State of Alert.

The phrase alert state is used in more than one professional discipline.

National defence

The phrase alert state is used in milieu variously, although in a capitalized form the reference is of an indication of the state of readiness of the armed forces for military action or a State against terrorism or military attack. The term frequently used is on High Alert [1] Examples are the DEFCON levels of the US armed forces, probably indicating some degree within DEFCON:2 to DEFCON:4, possibly DEFCON:1 classified with the words as high alert.[2]

The British government's UK Threat Levels, probably including the highest three levels of five, these being classified as substantial, severe and critical.[3] Both highest positions within the classification are synonymous with red alert. All these rely on an understanding of the word alert, which is also originally relevant to a type of military activity, within the earliest recorded usage.[4]

Psychology
