  FUNCTIONAL DAMAGE
  4-161. The attrition of ground forces is influenced by factors in the domains of battle: physical
  (personnel, weapons systems, and sustainment), cybernetic (C2), morale (will to fight), training, and
  leadership. Generally, the greater the personnel casualties and damage to their equipment and
  communications and supply networks, the greater the attrition of ground forces and the lower their
  combat effectiveness. Desertions or POW losses may also render a unit ineffective. As part of
  determining enemy combat effectiveness (ability to function), two factors must be addressed in clear and
  simple terms:
  • Reconstitution of forces and recuperation of facilities.
  • Residual capabilities to perform defense, assault, and supply missions.
  STORAGE TANKS FOR PETROLEUM, OIL, LUBRICANTS
  4-162. Although a POL tank may sustain damage, its contents may be retrievable and usable.
  PHYSICAL DAMAGE
  No Damage
  4-163. Military action has caused no apparent damage.
  Light to Moderate Damage, Aboveground Tanks
  4-164. Military action has punctured top walls, sidewalls, or both; possibly spilled contents; caused no
  evidence of sustained fire; left structural integrity intact.
  Light to Moderate Damage, Partly or Completely Underground Tanks
  4-165. Round has penetrated tank, but no secondary explosion or sustained fire has occurred.
  Destruction
  4-166. Military action has caused at least partial collapse or buckling of side wall; or, a secondary
  explosion or a sustained fire has occurred, or both.
  FUNCTIONAL DAMAGE
  4-167. Significant functional damage of a POL storage installation is expressed in terms of storage
  capacity rendered unusable and time required to repair or replace this denied capacity.
  POWER PLANT TURBINES AND GENERATORS
  4-168. Power plant turbines and generators may be housed in separate structures or together in a single
  structure called a "generator hall." Physical damage to the turbine or generator units can be difficult to
  identify if the generator hall remains relatively intact. Therefore, damage estimates to the units are based
  upon the location of the weapon detonation and on the physical damage to the building itself. The closer
  to the floor a weapon detonates, the greater the probability of unit damage. The extent and location of
  structural damage, as opposed to roof-panel damage, is another indicator of unit damage--the greater the
  wall damage and structural collapse, the greater the likelihood that the unit(s) is damaged or destroyed
  under the rubble.
  PHYSICAL DAMAGE
  4-169. When reporting physical damage, the team reports the number of turbines or generators that are
  damaged and destroyed out of the total number of units at the facility. When performing combat
  assessment on a generator hall, they report physical damage to both the building (see previous
  discussion), and they estimate damage to the turbines or generators located inside.
