Survivability has often been described as “blade time,” which refers to the time required for an engineer digging
asset to dig a fighting or protective position. This concept originated with survivability doctrine, first
introduced in Field Manual (FM) 5-103, Survivability, in 1985.1 This manual evolved from FM
5-15, Field Fortifications, which focused on engineering and provided details for constructing entrenchments,
emplacements, and shelters; it also outlined the principles of terrain appreciation as they apply to field
fortifications and explained how to combine individual field fortifications into a unified system
through the organization of the ground.2
As outlined in Army Techniques Publication (ATP) 3-37.34, Survivability Operations, survivability
doctrine is still primarily intended for engineer staffs and officers at the brigade echelon and below, almost
40 years after its inception.3
Survivability serves as the foundation of the protection warfighting function, which refers to “the related
tasks, systems, and methods that prevent or mitigate detection, threat effects, and hazards to preserve combat
power and enable freedom of action.”4 Therefore, survivability applies to all military personnel—not just
engineer formations and their staffs. All Soldiers and units carry out survivability operations within the
limits of their capabilities. It all begins with individual Soldiers and units conducting tactical-level
operations.
Soldiers can significantly enhance their survivability by being proficient at critical Soldier common tasks and
field craft—for example, applying personal camouflage; reducing personal electromagnetic signatures; reacting to
contact; protecting against chemical, biological, radiological, and nuclear (CBRN) injury/contamination; and
performing self-aid/first aid. All Soldiers must understand the threat, the operational environment, and all
forms of contact and consider the possibility of being under constant observation.
Survivability is also related to the ability of a unit to avoid enemy detection, defeat enemy detection
capabilities, and withstand enemy effects. Units can enhance the survivability by deploying local security
measures, adjusting movement and maneuver formations, taking evasive actions, maneuvering to gain positional
advantages, deploying decoys, dispersing forces, and carrying out military deception operations. Tactical units
should incorporate procedures for the use of camouflage, cover, concealment, and electromagnetic emissions
control—including noise and light discipline. The dispersal of formations also improves survivability by making
it harder for enemy forces to identify valuable targets. Additionally, the application of CBRN defense measures
improves survivability in CBRN environments.
A Soldier takes aim from his man-made fighting position.
For improved survivability, unit leaders must analyze the mission and fully comprehend the situation, problem,
and objectives. This will guide the planning process. If the current survivability measures are unable to
prevent detection or mitigate the impact of threats and hazards, then leaders should coordinate with higher
headquarters to acquire the necessary protection resources, thereby ensuring survivability and mission success.
Common survivability enablers include—
- Engineers, who construct fighting positions, protective positions, and hardening facilities and employ
protective obstacles.
- Obscuration, which results from natural (rain, fog) or artificial causes or occurs as a by-product (smoke,
dust).
- Electromagnetic protection, which includes the employment of countermeasures, the mitigation of signatures,
and electromagnetic hardening.
- CBRN operations, which include the employment of capabilities that assess, protect against, and mitigate the
entire range of CBRN incidents to enable freedom of action.
- Tactical deception, which refers to friendly activity that causes enemy commanders to take action or cause
inaction detrimental to their objectives.
- Operations security, which is a capability used to identify and control critical information, indicate
friendly force actions attendant to military operations, and incorporate countermeasures to reduce the risk
of adversarial exploitation of vulnerabilities.
- Force health protection, which encompasses measures that promote, improve, or conserve the behavioral and
physical well-being of Soldiers. These measures comprise preventive and treatment aspects of medical
functions and include combat and operational stress control, medical services, dental services, operational
public health and laboratory services, and veterinary service.
