  MAP REHEARSAL
  D-15. A map rehearsal is normally the easiest technique to set up since it requires only maps and graphics
  for current operations; however, it is time consuming. The map rehearsal has many variations. The most
  common is to use a large scale map and operations overlay laid on a table with the participants seated around
  the map.
  D-16. Markers (such as cardboard cutouts, self-sticking note pads) are used to track each unit as it moves and
  each event as it occurs. Participants are responsible for representing their scheme of maneuver with the
  markers.
  D-17. This method requires the least terrain of all rehearsals. An optimal site overlooks the terrain where the
  unit will execute the operations.
  SKETCH-MAP REHEARSAL
  D-18. This method uses a large scale sketch-map of the operations overlay and key terrain features; the sketch
  is used in the same manner as the map. A technique is to draw this sketch on the side of a tracked vehicle.
  Yet another option is to move to an area overlooking the operations terrain and have the participants use their
  own maps and overlays to follow the rehearsal. This technique has the added advantage of familiarizing the
  participants to the terrain. The sketch map technique is one of the two most commonly used rehearsal
  techniques (the other is the map rehearsal).
  D-19. The procedures for this rehearsal are the same as for a terrain-model rehearsal (see paragraph D-22)
  except the commander uses a sketch map in place of a terrain model. Sketch-map rehearsals take less time
  than terrain-model rehearsals but more time than map rehearsals.
  DIGITAL TERRAIN MODEL REHEARSAL
  D-20. Digital terrain models are virtual representations of the AO. The time it takes to create the digital three-
  dimension model depends on the amount of available data on the terrain being modeled. An accurately
  constructed terrain model helps subordinate leaders visualize the commander's intent and concept of
  operations.
  D-21. This type of rehearsal is best suited to small units, such as SHORAD batteries and platoons. However,
  with a suitable local area network, a wider audience can view the graphics.
  TERRAIN-MODEL REHEARSAL
  D-22. The terrain-model rehearsal takes less time and fewer resources than a full-dress or reduced-force
  rehearsal. Like the digital terrain-model, an accurately constructed model helps subordinate leaders visualize
  the commander's intent and concept of operations. When possible, place the terrain model where it overlooks
  the actual terrain of the AO. However, if the situation requires more security, place the terrain model on a
  reverse slope within walking distance of a point overlooking the AO. The model's orientation coincides with
  that of the terrain.
  D-23. Integrating air defense information into a supported unit's terrain model is critical. Ensuring the enemy
  air avenues of approach, possible enemy aerial targets, potential landing zones, and weapons engagement
  ranges are depicted is crucial to ensuring all participants understand the enemy air capabilities.
  KEY LEADER REHEARSALS
  D-24. A key leader rehearsal involves only key leaders of the organization and its subordinate units. Terrain
  requirements can be the same as for a full-dress rehearsal, even though there are fewer participants. The
  commander decides the level of leader involvement. The selected leaders then rehearse the plan while
  traversing the actual or similar terrain. This technique is useful to rehearse fire control orders and rules of
  engagement for an engagement area during defensive operations. A key leader rehearsal may be used to
  prepare key leaders for a full-dress rehearsal.
