  forward to avoid detection. They normally include the echelon’s tactical command post, which co-locates
  with the main command post of the outgoing unit. Commanders may also attach liaison personnel to
  subordinate units to ensure a smooth transition between units.
  CONTROL MEASURES FOR A RELIEF IN PLACE
  15-7. Control measures associated with a relief in place are generally restrictive to prevent fratricide. At a
  minimum, these measures include the assigned area with its associated boundaries and current positions.
  Other graphics to help with the coordination of the relief in place include—
  * Point control measures such as coordination points, contact points, start points, and release points.
  * Movement control measures such as routes, passage lanes, and gaps.
  * Assembly areas.
  * Fire support coordination measures such as target reference points and engagement areas and
  defensive direct fire control measures, such as TRPs and engagement areas.
  Units may use any additional graphic control measures necessary to prevent fratricide and to control a relief
  in place. Figure 15-1 depicts an example brigade relief in place.

  PLANNING A RELIEF IN PLACE
  15-8. Once ordered to conduct a relief in place, the incoming unit contacts the outgoing unit. If possible,
  they coordinate to co-locate their command posts to facilitate coordination between the two units. If the
  outgoing unit’s forward elements can defend the assigned area, the incoming unit executes the relief in place
  from the rear to the front. This facilitates movement and terrain management.
  15-9. In a deliberate relief, units exchange plans and liaison personnel, conduct briefings, perform detailed
  reconnaissance, and publish orders with detailed instructions. In a hasty relief, commanders abbreviate the
  planning process and control execution. In both cases, the outgoing unit designates liaison personnel from its
