  elements early to delay, disrupt, or limit the enemy's advance into the security area. The CFL should be kept
  as close as possible to the FLOT in both offensive and defensive operations. FS personnel must maintain
  continual awareness of SOF, multinational and unified action partners operating beyond the FLOT to
  expedite clearance of fires and reduce chances of fratricide. See figure 6-2.

  FIRE SUPPORT CONSIDERATIONS AND THE CHARACTERISTICS
  OF THE DEFENSE
  6-38. Successful defenses are aggressive and strive to regain the initiative from attacking enemy forces. FS
  plays a critical role in facilitating the following characteristics of the defense. The characteristics of the
  defense are disruption, flexibility, maneuver, mass and concentration, operations in depth, preparation, and
  security.
  DISRUPTION
  6-39. Disruption actions include deceiving or destroying enemy reconnaissance forces, breaking up combat
  formations, separating echelons, and impeding an enemy force's ability to synchronize its combined arms.
  FS plays a key role in disrupting an attacker's tempo and synchronization. Considerations include:
  * Employ fires to neutralize and destroy enemy artillery and mortar, TA, C2 nodes, and logistics
  systems.
  * Disrupt enemy sustainment efforts and troop movements (consider destroying bridges).
  * Ensure integration of fires in support of obstacles.
  * Assist in defeating enemy reconnaissance forces, separating enemy forces, isolating enemy units,
  and attacking or disrupting enemy systems.
