Terrain analysis introduction
The capability to move men and materials from one point to another in an
operational area is an essential ingredient of combat power and is often decisive to the
outcome of a battle. Planning and maneuvering are dependent not only on the existence
and knowledge of adequate lines of communication in a combat zone; knowledge of the
terrain is also essential. The commander must have accurate intelligence on the surface
configuration of the terrain, including slope, landform, and surface roughness.
This information is important because the type of landform, steepness of slope, and
roughness of the terrain surface influence cross country mobility; indeed, consideration of
these terrain conditions is necessary for proper maneuver planning.
