  defeat small unit operations (Level I or Level II threats). Units must use adequate cover and
  concealment measures to prevent detection by enemy forces. Cover and concealment measures must
  also address electromagnetic spectrum, acoustic, and thermal signatures generated by sustainment
  units. Dispersion mitigates effects of long-range fires and attack aircraft. See ADP 3-37 for more
  information.
  • Plan for adequate convoy security for convoys supporting the mobile defense. This may be from
  internal sources or from coordinated external sources.
  • Plan for CBRN conditions. CBRN defense plans should include assessment (threat assessments,
  detection methods, reconnaissance, and surveillance plans), protection, and mitigation strategies
  (dispersion, covers). This includes an increase in requirements for non-potable water and CBRN
  defense equipment. Sustainment planners should anticipate the effects of CBRN conditions. This
  includes impacts to supply routes and increased requirements for non-potable water and chemical
  defense equipment such as individual protective equipment, filters, and CBRN medical
  countermeasures. CBRN defense planning must include detailed procedures for assessing the threat,
  protecting people, resources, and equipment, and mitigating the impact. For more information see
  FM 3-11.
  • Plan for processing contaminated human remains and equipment decontamination. In accordance
  with DOD and Federal policy, the safety of the living takes precedence over the evacuation of
  contaminated remains. If unable to be decontaminated for transport, contaminated human remains
  will not depart the theater of operations. Sustainment planners must identify and resource cold
  storage or execute interment operations. For more information on decontamination of human
  remains, see ATP 4-46.
  ADDITIONAL PLANNING CONSIDERATIONS
  5-157. The many implications for the tactics, techniques, and procedures used by sustainment forces
  supporting a defense are just as significant as commodity requirements. Sustainers anticipate how terrain,
  defensive obstacles, fire support coordination measures, and movement restrictions will affect sustainment
  operations. These factors are considered in all distribution management and movement control plans.
  Planners expect to weight sustainment operations support for spoiling attacks, counter attacks, and follow-
  on offensive operations. This may require sustainers to weight the main defensive effort by cross-leveling
  sustainment assets. In some cases, sustainers pre-position Class I, IIIB/P, IV, V, VII, VIII, and IX stocks and
  water centrally and well forward, but they always balance forward positioning of sustainment assets with the
  need for rapid mobility. While supporting covering, guard, and screening forces and counter and spoiling
  attack forces, sustainers plan for support elements to operate outside the unit boundaries and beyond the
  forward line of own troops. Sustainers also consider operational control measures to include passage of lines
  with maneuver forces in perimeter defense. Finally, sustainment leaders identify sustainment forces that will
  support the defense reserve force in all types of defensive operations. Commanders determine what risk is
  acceptable in attaching sustainment units to that reserve force.
  5-158. Defensive operations also place a burden on medical resources due to the magnitude and lethality of
  forces involved. Medical units anticipate large numbers of casualties in a short period of time due to the
  capabilities of modern conventional weapons and the possible employment of weapons of mass destruction.
  These mass casualty situations can exceed the capabilities of organic and direct support medical assets. To
  mitigate this risk, planners should anticipate the possibility for mass casualty situations and coordinate with
  area support medical units to help absorb the acute rise in battlefield injuries. The command surgeon or
  medical operations officer at echelon works with the logistics, personnel, and operations officers to develop
  mass casualty plans and advise commanders on integrating all available resources into an effective plan.
  Casualty evacuation is a unit-level responsibility and must occur concurrently with operations.
  5-159. Unit commanders must plan for and ensure the availability of casualty evacuation assets to augment
  available ambulances in the event of a mass casualty situation. Unit commanders must also ensure integration
  of the casualty evacuation plan with the medical evacuation plan. Evacuation of casualties during a mobile
  defense is especially challenging due to possible relocation of receiving MTFs and threats to evacuation
  routes. Units should always plan for mass casualty situations and have an evacuation plan, including
  identification of casualty evacuation assets and casualty collection points. The casualty evacuation plan
  should complement and be synchronized with the medical evacuation plan (ambulance shuttle system and
