  commanders and their staffs. The fire support plan includes a map with
  graphics outlining the following control lines:
  • Coordinated Fire Line. A line beyond which indirect fire systems
  can fire at any time within the AOR of the establishing headquarters
  without additional coordination.
  • Final Coordination Line. A line established by the appropriate
  maneuver commander to ensure coordination of fire of converging
  friendly forces. It can be used to prohibit fires or the effects of fires
  across the line without coordination with the affected force. For
  example, this line may be used during link-up operations between an
  airborne or heliborne insertion and converging ground forces.
  • Joint Fire Line. A line established by the appropriate OSC-level and
  above commander to ensure coordination of fire not under his control
  but which may affect his operations. The joint fire line is used to coor-
  dinate fires of air, ground, or sea weapons systems using various types
  of ammunition against surface targets.
  • Safety Line. A line that denotes the fragmentation footprint of
  indirect fire munitions or bombs/rockets released from aircraft.
  This indicates the minimum distance between the impact area and
  the nearest friendly troops.
  ASSIGNING FIRE MISSIONS
  7-39. When assigning missions, indirect fire support commanders and plan-
  ners consider several variables, depending on the situation. These variables
  include
  • Type of target (for example, equipment or personnel, deliberate or
  hasty defensive positions, hard- or soft-skinned vehicles, point or area
  targets).
  • Deployment of target (dug-in or in the open).
  • Whether the target is stationary or moving.
  • Whether the target is under direct observation during the artillery
  attack.
  • Range to the target.
  • Type, caliber, and number of weapons engaging the target.
  • Types of ammunition available.
  • Time available to prepare for firing.
  PRECISION MUNITIONS
  7-40. The OPFOR defines a precision weapon as one capable of delivering
  guided conventional munitions with a high probability of destroying enemy
  targets with a first-round hit (within range of the weapon delivery system).
  The presence of the precision munition transforms a weapon into a precision
  weapon. However, a precision weapon system must also incorporate a target
  acquisition and tracking subsystem and a missile or projectile guidance sub-
  system. Some of these subsystems may be combined. Precision munitions are
  primarily designed to effectively defeat armored vehicles; self-propelled artil-
  lery systems; MRLs; C2 and RISTA centers; defensive fortifications; and bridges.
