3-79. While conducting offensive operations, commanders place special emphasis on protection tasks related to survivability and detention operations. All units are responsible for improving their positions, regardless of role or location. Survivability is a quality or capability of military forces which permits them to avoid or withstand hostile actions or environmental conditions while retaining the ability to fulfill their primary mission (ATP 3-37.34). Survivability operations consist of four tasks which enhance the ability to avoid or withstand hostile actions by altering the physical environment: constructing fighting positions, constructing protective positions, hardening facilities, and employing camouflage and concealment. (See ATP 3-37.34 for additional information on survivability.)
