  5-149. Units can employ their reserves in spoiling attacks to throw the enemy’s offensive preparations off
  their timetable. In this case, commanders assume the risk of not having a reserve or designate other forces as
  their echelon reserve. The following considerations affect a spoiling attack:
  * Commanders may want to limit the size of the forces used in executing their spoiling attacks.
  * Units do not conduct spoiling attacks if the loss or destruction of the friendly attacking force would
  jeopardize the defending force’s ability to accomplish the defensive mission.
  * The mobility of the force available for the spoiling attack should be equal to or greater than that
  of the targeted enemy force.
  * Operations by artillery, aviation, or electromagnetic systems to prevent enemy elements not in
  contact from interfering with the spoiling attack are necessary to ensure the success of the
  operation.
  5-150. There are two conditions that must be met to conduct a successful spoiling attack:
  * The spoiling attack’s objective must be obtainable before the enemy force can respond to the attack
  in a synchronized and coordinated manner.
  * Commanders must prevent the overextension of forces conducting their spoiling attacks.
