text: Army Tactics
  depends on established and rehearsed unit-level mass casualty plans. There are a number of other variables
  which can ensure the success of a unit's mass casualty response. These include, but are not limited to—
  * Coordination of additional medical support and augmentation of medical evacuation support,
  forward resuscitative and surgical detachments, combat support and field hospitals, casualty
  collection points, ambulance exchange points, and established Class VIII resupply.
  * Rapid clearance of casualties from the battlefield (independent of MEDEVAC).
  * Providing effective tactical combat casualty care for the injured.
  * Continuous flow of casualties to the medical treatment facilities at the next higher role of care.
  * Use of alternative assets when the number of casualties overwhelms the capacity of available
  medical evacuation systems.
  PROTECTION WARFIGHTING FUNCTION
  1-171. The protection warfighting function is the related tasks, systems, and methods that prevent or
  mitigate detection, threat effects, and hazards to preserve combat power and enable freedom of action (FM
  3-0). Protection encompasses everything that makes the Army forces hard to detect and hard to destroy.
  Protection requires units to understand and visualize threats and hazards in an operational environment. This
  understanding allows units to prioritize their requirements and commit capabilities and resources according
  to those priorities. The protection warfighting function is the responsibility of all unit types and echelons in
  order to maintain the force’s integrity and combat power.
  1-172. The protection warfighting function includes these tasks:
  * Conduct survivability operations.
  * Coordinate air and missile defense support.
  * Conduct populace and resources control.
  * Conduct electromagnetic protection.
  * Perform cyberspace security and defense.
  * Provide force health protection.
  * Conduct CBRN operations.
  * Provide explosive ordnance disposal support.
  * Conduct personnel recovery.
  * Conduct detention operations.
  * Conduct risk management.
  * Implement physical security procedures.
  * Apply antiterrorism measures.
  * Conduct police operations.
  * Conduct area security.
  * Implement operations security.
  Survivability Operations
  1-173. 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/MCTP 3-34C). Survivability operations are those protection activities that alter the physical
  environment by providing or improving cover, camouflage, and concealment (ATP 3-37.34/MCTP 3-34C).
  Units exploit existing terrain features to enhance their survivability by altering the physical environment to
  provide or improve their cover and concealment. Likewise, units can use natural or manmade materials as
  camouflage to confuse, mislead, or evade the enemy to enhance their survivability.
  1-174. All units conduct survivability operations within the limits of their capabilities. These include
  camouflaging their positions and constructing individual or crew served fighting positions. Engineers and
  CBRN units possess additional capabilities to assist survivability operations. These include hardening
  structures and positions and the reconnaissance, surveillance, and decontamination of CBRN hazards.
