  Perform Cyberspace Security and Cyberspace Defense
  1-187. The Army secures and defends the network through a defense-in-depth approach, incorporating
  layered security and defenses. The tasks to secure and defend cyberspace are—
  * Perform cybersecurity activities.
  * Conduct defensive cyberspace operations-internal defensive measures.
  1-188. Cyberspace security are actions taken within protected cyberspace to prevent unauthorized access
  to, an exploitation of, or damage to computers and networks, including platform information technology
  (JP 3-12). Cyberspace security is not specific to an enemy or adversary. Cyberspace security actions protect
  the networks and systems through all phases of network planning and implementation. Cyberspace security
  activities include vulnerability assessment and analysis, vulnerability management, incident handling,
  continuous monitoring, and detection and restoration capabilities to shield and preserve information and
  information systems.
  1-189. Cyberspace defense are actions taken within protected cyberspace to defeat specific threats that have
  breached or are threatening to breach cyberspace security measures (JP 3-12). The purpose of cyberspace
  defense includes actions to protect, detect, characterize, counter, and mitigate threats. Such defensive actions
  are usually created by the joint force command or Service that owns or operates the network, except in cases
  where these defensive actions would affect the operations of networks outside the responsibility of the
  respective joint force command or Service.
  Force Health Protection
  1-190. Force health protection are measures that promote, improve, or conserve the behavioral and physical
  well-being of Soldiers comprised of preventive and treatment aspects of medical functions that include
  combat and operational stress control, dental services, veterinary services, operational public health, and
  laboratory services. Enabling a healthy and fit force, prevent injury and illness, and protect the force from
  health hazards (FM 4-02). (See FM 4-02 for additional information on force health protection).
  Chemical, Biological, Radiological, and Nuclear
  1-191. CBRN support to operations include the simultaneous application of the assess, protect, and mitigate
  functions guided by hazard awareness and understanding. CBRN units enable movement and maneuver of
  supported units in accordance with the concept of operations and scheme of maneuver.
  1-192. CBRN staff assess potential CBRN threats and hazards and recommend mitigation measures to
  protect the force while minimizing degradation of units, personnel, equipment, and facilities from effects that
  would hinder operations. CBRN staffs advise units on risks and friendly vulnerabilities through their
  understanding of the operational environment and the enemy’s capabilities. Measures to protect against and
  mitigate CBRN effects include proper protective equipment, exposure guidance, and alarm conditions.
  1-193. CBRN operations include active measures to gain information on CBRN threats, enabling units to
  mitigate these threats and limit vulnerabilities while continuing operations. CBRN defense measures include
  individual, crew, and collective tasks. Units conduct CBRN reconnaissance and surveillance operations as
  complementary operations to facilitate maneuver by understanding the CBRN hazards. The time, techniques,
  and CBRN assets required to achieve reconnaissance objectives are determined by the intelligence
  requirements and mission variables. CBRN protection and mitigation measures increase the ability of the
  force to operate under CBRN conditions but may decrease operational tempo and increase sustainment
  requirements. (See FM 3-11 for more information on CBRN operations).
  Personnel Recovery
  1-194. Soldiers have an increased likelihood of becoming isolated during offensive operations. Units must
  train both the individual and staff on how to react when an isolating event occurs. Army personnel recovery
  is the military efforts taken to prepare for and execute the recovery and reintegration of isolated personnel
  (FM 3-50). Training includes the personnel recovery tasks of report, locate, support, recover, and reintegrate
  as well as the Code of Conduct and individual isolation tasks (survive, resist, escape, evade).
