5-42: Terrain Association

Previous: 5-41: Types of Navigation

5-42. Terrain association is the ability to identify terrain features on the ground by the contour intervals depicted on the map. The leader analyzes the terrain using the factors of OAKOC, and identifies major terrain features, contour changes, and man-made structures along his axis of advance. As the unit moves, he uses these features to orient the unit and to associate ground positions with map locations. The major advantage of terrain association is it forces the leader to continually assess the terrain. This leads to identifying tactically-advantageous terrain and using terrain to the unit’s advantage.
