  ARTILLERY TARGET INTELLIGENCE ZONE
  B-69. An artillery target intelligence zone is a weapons locating radar search area in enemy territory
  that the commander monitors closely to detect and report any weapon ahead of all acquisitions other
  than those from critical friendly zones or call for fire zones.
  B-70. Artillery target intelligence zones may be established in areas where we are not sure about threat
  indirect fires and need to develop the situation. They can also be used in areas of suspect threat indirect fires
  that the commander wishes to monitor closely but are out of friendly indirect fire range. When possible, the
  effective date-time-group (moveable and scalable) should be placed within the graphic boundary, but it may
  be placed outside the graphic if necessary.
  B-71. An artillery target intelligence zone is graphically portrayed (see figure B-18) by a solid black line
  defining the area and the letters "ATI," followed by the establishing HQ within plus the effective date-time-
  group. The artillery target intelligence zone requires a minimum of three and a maximum of six anchor points
  to define the boundary of the area. The size and shape of the CFFZ is determined by the anchor points and
  may be circular, rectangular, or irregular.
