  8-121. Units develop, train, and rehearse a CBRN protection plan to protect personnel and equipment from
  CBRN hazards. Units conduct mission-oriented protective posture level analysis results to determine initial
  individual protective equipment levels, decontaminants, water, and other CBRN equipment requirements.
  Higher echelon headquarters often establish the mission-oriented protective posture level. Force health
  personnel maintain situational awareness and surveillance of personnel strength information for indications
  of force contamination, epidemics, or other anomalies apparent in force health data. Units ensure that they
  can conduct CBRN defense measures including surveillance, protection and decontamination of military
  personnel and equipment. Commanders are responsible for CBRN passive defense training to prepare the
  unit to operate in a CBRN environment.
  8-122. CBRN personnel contribute to the overall protection of units located in defensive positions. Units
  employ CBRN reconnaissance and surveillance elements along movement routes and at potential choke
  points. CBRN vulnerability assessments provide a list of recommended preventive measures for units to
  consider before and after they move into their defensive positions. These assessments provide a list of
  preventive measures that can range from mission-oriented protective posture levels, CBRN agent
  characteristics on persistency and volatility, to establishing or activating collective protection systems and
  establishing personnel and equipment decontamination sites. Proper use of CBRN assets enables units to
  reduce casualties and complete the mission. (See FM 3-11 for more information on CBRN operations.)
  Operations Security
  8-123. As part of the defense, the echelon’s OPSEC program and any military deception or survivability
  efforts should conceal the locations of defensive positions, engineer support, the disposition of forces, and
  the timing of any offensive operations from the enemy or mislead the enemy regarding this information.
  These measures prevent the enemy from launching effective spoiling attacks. (For more information on
  military deception see FM 3-13.4. For more information on operations security see ATP 3-13.3.)
  Explosive Ordnance Disposal
  8-124. Explosive ordnance disposal elements provide the capability to detect, identify, evaluate, render safe,
  exploit, and dispose of explosive hazards to ensure friendly forces maintain their freedom of movement.
  These elements can also render safe and dispose of explosive hazards that deny access to or threaten supplies,
  facilities, and other critical assets. These hazards can include conventional unexploded ordnance, high-yield
  explosives and associated materials, improvised explosive devices, and weapons of mass destruction.
  Explosive ordnance disposal may dispose of hazardous foreign or U.S. ammunition; unexploded ordnance;
  and individual, booby-trapped, and chemical mines. Breaching and clearance of minefields is primarily an
  engineer responsibility (See ATP 4-32 for more information on explosive ordnance disposal operations).
  Detention Operations
  8-125. During the defense, units must plan for capturing numerous detainees, most of whom are categorized
  as enemy prisoners of war. The classification of these detainees varies according to operational environments.
  Defending units may capture individual detainees or entire enemy units separated and disorganized from
  combat. Unit staffs consider detention operations when developing defensive plans. Planners account for all
  aspects of detainee operations while planning for the supported operation. To ensure that units are prepared
  to incorporate detainee operations during planning, units establish mechanisms that ensure effective
  consideration of potential detainee operations and their supporting activities. Units monitor the actual number
  of detainees closely to avoid devoting too many or too few resources to detainee operations.
  8-126. All Soldiers participating in military operations must be prepared to process and safeguard detainees.
  Actions at the point of capture—the point at which a Soldier has the custody of, and is responsible for
  safeguarding, a detainee—can directly affect mission success and could have a lasting impact on U.S. tactical,
  operational, and theater strategic military objectives. Military police are trained in detainee operations and
  support the force by relieving units of detainees to reduce the impact on combat forces. (See FM 3-63 for
  more information on detainee operations.)
