Planning 07 December 2020 ATP 5-0.2-1 85 ATP 2-01.3 Figure 2-20. Modified combined obstacle overlay example Terrain Effects Matrix 2-256. A terrain effects matrix is helpful in explaining an analysis of the terrain. Using the MCOO as a guide, a terrain matrix describes the military aspects of terrain on friendly and threat operations. The military aspects of terrain are evaluated by identifying OAKOC. Key terrain is often selected as a decisive point and a tactical-level or operational-level objective. Evaluate the other four military aspects of terrain first; then integrate those results to identify and assess key terrain. For example, key terrain might include a range of hills with good observation and fields of fire overlooking an area providing adversary forces a number of high-speed avenues of approach (see table 2-22 on page 86 for an example terrain effects matrix).
