2-255. All units have the inherent responsibility to conduct survivability operations and continually improve their positions. Although there are three general categories of threats and hazards (hostile actions, nonhostile actions, and environmental conditions), survivability is most concerned with avoiding or withstanding the threats posed by hostile actions and environmental conditions. The four tasks associated with survivability operations are constructing fighting positions, constructing protective positions, hardening facilities, and employing camouflage and concealment. All four tasks are often addressed in combination. Some additional factors which can enhance an organization’s ability to avoid or withstand threats and hazards include dispersion, redundancy, leadership, discipline, mobility, situational understanding, terrain management, and CBRN planning. The loss or severe degradation of unit CPs and other key facilities by enemy attacks in the physical and cyberspace domains can prevent the successful execution of missions. A CP or key facility’s size, immobility, and multispectral signature invites enemy attack and the resulting disruption of the friendly tempo of operations. Survivability of those critical assets that enable a high operational tempo are a top priority. (See ATP 3-37.34 for additional information on survivability operations.)
