DIGITAL TERRAIN-MODEL REHEARSAL
Rehearsals
8-32. With today’s digital capabilities, users can construct terrain models in virtual space. Units drape
high-resolution imagery over elevation data thereby creating a fly-through or walk-through. Holographic
imagery produces the view in three dimensions. Often, the model hot links graphics, detailed information,
unmanned aircraft systems, and ground imagery to key points providing more insight into the plan. Digital
terrain models reduce the operations security risk because they do not use real terrain. The unit geospatial
engineers or imagery analysts can assist in digital model creation. Detailed city models already exist for
many world cities.
8-33. The time it takes to create the digital three-dimensional model depends on the amount of available
data on the terrain being modeled.
8-34. Of all the echelons involved, this type of rehearsal best suits small units, although with a good local
area network, a wider audience can view the graphics. All echelons may be provided copies of the digital
model to take back to their headquarters for a more detailed examination.
8-35. If not placed on a computer network, there is limited operations security risk because no site is
secured and the rehearsal can be conducted under cover. However, if placed on a computer network, digital
terrain models can be subject to enemy exploitation due to inherent vulnerabilities of networks.
8-36. This space requires the least terrain of all rehearsals. Using tents or enclosed areas conceal the
rehearsal from the enemy.
SKETCH-MAP REHEARSAL
8-37. Commanders can use the sketch-map technique almost anywhere, day or night. The procedures are
the same as for a terrain-model rehearsal except the commander uses a sketch map in place of a terrain
model. Large sketches ensure all participants can see as each participant walks through execution of the
operation. Participants move markers on the sketch to represent unit locations and maneuvers.
8-38. Sketch-map rehearsals take less time than terrain-model rehearsals and more time than map
rehearsals.
8-39. Units gear a sketch map to the echelon conducting the rehearsal. Multiechelon rehearsals using this
technique are difficult.
8-40. This rehearsal can present operations security risks if the area around the rehearsal site is not
secured. Assembled commanders and their vehicles can draw enemy attention. Units must sanitize, secure,
or destroy the sketch map after use.
8-41. This technique requires less terrain than a terrain-model rehearsal. A good site ensures participants
can easily find it yet stay concealed from the enemy. An optimal location overlooks the terrain where the
unit will execute the operation.
MAP REHEARSAL
8-42. A map rehearsal is similar to a sketch-map rehearsal except the commander uses a map and operation
overlay of the same scale used to plan the operation.
8-43. The map rehearsal itself consumes the most time. A map rehearsal is normally the easiest technique
to set up since it requires only maps and graphics for current operations.
8-44. Units gear a map rehearsal’s operation overlay to the echelon conducting the rehearsal. Multiechelon
rehearsals using this technique are difficult.
8-45. This rehearsal can present operations security risks if the area around the rehearsal site is not
secured. Assembled commanders and their vehicles can draw enemy attention.
8-46. This technique requires the least terrain of all rehearsals. A good site ensures participants can easily
find it yet stay concealed from the enemy. An optimal location overlooks the terrain where the unit will
execute the operation.
