  Linkup Point
  A-27. A linkup point is a designated place where two forces are
  scheduled to meet. This easily identifiable point on the ground is
  where two forces meet or consolidate before proceeding on with their
  mission. Besides being easily identifiable, the linkup point must also be
  rather inconspicuous, or the enemy will be able to predict the location
  of the coordination and quickly target it. It should also be relatively
  isolated from direct fire and observation of possible enemy elements
  located on the surrounding terrain. Alternate linkup points must meet
  the same criteria and should be reconnoitered to the same degree as
  primary linkup points. Linkup points are normally positioned behind or

  along one flank of the enemy’s positions on defensible terrain and
  located away from normal enemy troop movement routes. The linkup point should be large enough for all
  infiltrating elements to assemble, and it should offer cover and concealment for these elements. Figure A-14
  depicts LINKUP POINT 8.
  Named Area of Interest
  A-28. A named area of interest is the geospatial
  area or systems node or link against which
  information that will satisfy a specific
  information requirement can be collected,
  usually to capture indications of enemy and
  adversary courses of action (JP 2-0). In this
  latter case, the NAI may be a person, group, or
  portion of cyberspace. Staffs tailor the shape of
  their NAI symbols to the actual area they want
  observed rather than using a prescribed shape. It
  is possible to re-designate a NAI as a target area
  of interest (TAI) when Soldiers confirm enemy
  activity in the area and have assets that can
  target it. This allows commanders to mass the Figure A-15. Named area of interest AUGUSTA
  effects of combat power on that area. Figure A-

  Objective
  A-29. An objective is a location used to orient operations, phase operations, facilitate changes of direction,
  and provide for unity of effort (ADP 3-90). Objectives should be easily identifiable on the ground to facilitate
  their recognition. They normally assign subordinate commanders only their final objectives, but they can
  assign intermediate objectives as necessary. Figure A-19 on page A-11 depicts OBJECTIVE PAT.
  OBJECTIVE PAT is further divided into two subordinate objectives: OBJECTIVE KAI and OBJECTIVE
  ZEKE.
  Passage Lane
  A-30. A passage lane is a lane through an obstacle that provides safe
  passage for a passing force. It is a clear route through an obstacle. The
  lane may be cleared, including being reduced and proofed, as part of a
  breach operation, or it may be included as part of the design of a friendly
  obstacle. Passage lanes normally end where a route begins. That route
  should allow the passing unit to move rapidly through the stationary
  unit’s area. Figure A-16 depicts the graphic control measure for a
  passage lane.
