  • The ability of the engineering resources to provide--
  -- Mobility,
  -- Countermobility, and
  -- Survivability support.
  TYPES OF EQUIPMENT
  4-155. Types of equipment whose reduction in capability can affect the functioning of a site or
  element include--
  Armored Vehicles and Artillery--Functional damage is an elimination of firepower capability
  (F-kill), prevention of mobility (M-kill), or both, which the crew cannot repair on the
  battlefield.
  Trucks--Functional damage is a reduction in mobility (M-kill) or in ability to use the truck's
  internal equipment for a number of hours until the crew can repair the equipment or vehicle.
  Locomotives and Rolling Stock--Functional damage is prevention of mobility (M-kill) for a
  number of hours until the crew can repair the locomotive or rolling stock cars. Functional
  damage can also include damage or destruction of materials within the cars.
  Aircraft--Functional damage prevents takeoff (PTO-kill) for a number of hours until the crew can
  repair it.
  Rocket, Missile, or Launcher--Functional damage prevents successful or effective firing of the
  weapon (F-kill). The crew cannot repair this damage on the battlefield.
  Radar Antenna or Its Van or Trailer--Functional damage prevents a radar system from
  acquiring, firing, or tracking missiles (F-kill) until the system can be repaired.
  GROUND FORCE PERSONNEL
  4-156. Damaging or destroying an occupied position such as a bunker, trench, or other structure or a
  vehicle such as a personnel carrier or truck usually causes casualties. FM 6-30 states that for indirect fire,
  thirty-percent casualties or materiel damage inflicted during a short time span normally renders a unit
  ineffective. However, a commander will stipulate the desired effects and percentages required for
  success against specific target categories.
  PHYSICAL DAMAGE
  4-157. In addition to reporting physical damage levels, the team should estimate the total percentage of
  the ground force destroyed. For equipment, see the damage definitions provided for military equipment.
  No Damage
  4-158. Military action has caused no apparent damage.
  Damage
  4-159. Military action has caused up to 30 percent casualties to visible personnel or to occupied
  positions or organic equipment.
  Destruction
  4-160. Military action has caused more than 30 percent casualties to visible personnel or to occupied
  positions or organic equipment.
