  16-6. The planning focus for both the passing unit and the stationary unit is on operations following the
  passage. While this occurs, the two units involved coordinate the following:
  * The exchange of intelligence and combat information to include products and databases.
  * Current friendly dispositions and tactical plans, especially deception and obstacle plans.
  * Direct and indirect fires and close air support plans.
  * Any graphic control measures and graphics not directed by the higher headquarters, such as
  boundary changes, the battle handover lines, emergency logistics points, and assembly area and
  firing positions for artillery, air defense, and other units.
  * Long-range and short-range recognition symbols and vehicle markings to reduce the probability
  of fratricide.
  * Signal operating instruction details, such as call signs, frequencies, and recognition signals.
  * Time and conditions for transfer control of the assigned areas from one headquarters to the other,
  if not previously established.
  * Provisions for movement control, including contact points, start and release points, primary and
  alternate routes, route selection, priorities for using routes and facilities, passage points, and
  provision for guides.
  * Reconnaissance by elements of the passing unit.
  * Security measures during the passage, including nuclear, biological, and chemical reconnaissance
  or biological detection systems.
  * Fires, obscurants, and any other combat sustainment provided by the stationary unit.
  * Measures to reduce both units’ vulnerability to attack by enemy weapons of mass destruction.
  * Operations security measures required before or during the passage.
  * Allocation of terrain for use by the passing force.
  * Air defense cover—up to and forward of the battle handover line.
  * Sustainment support for the passing unit provided by the stationary unit, especially fuel,
  maintenance, and medical treatment.
  * Population of icons within computer systems that track friendly system and unit locations to
  increase situational awareness and reduce the probability of friendly fire incidents.
  * Detailed isolated Soldier guidance.
  ORGANIZATION OF FORCES FOR A PASSAGE OF LINES
  16-7. A unit may participate in a passage of lines as either the passing or the stationary force. Performance
  of a passage of lines does not require a special task organization with the exception that the stationary force
  provides guides and sustainment assets to expedite the movement of the passing force. Both the passing and
  stationary forces maintain their previous combat organization during the passage. The stationary unit
  conducts operations against enemy forces that can interfere with the passage if it has the capability to do so.
  However, operations directed against enemy forces may be the responsibility of a higher echelon, depending
  on the echelon at which the passage takes place.
  16-8. A forward passing unit’s order of march is generally reconnaissance and security elements first. The
  main body moves next, followed by functional and multifunctional support and sustainment elements. The
  overall headquarters integrates artillery and engineers into the order of march based on the mission variables.
  The passing unit reverses this order of march in a rearward passage of lines. Attack helicopters and armed
  UASs are useful in providing security to the passing force.
  CONTROL MEASURES FOR A PASSAGE OF LINES
  16-9. Control measures associated with a passage of lines are generally restrictive to prevent fratricide. At a
  minimum, they include:
  * Assigned area.
  * Assembly areas.
  * Attack positions.
