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

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]
