The modified combined obstacle overlay is a joint intelligence preparation of the operational environment product used to portray the militarily significant aspects of the operational environment, such as obstacles restricting military movement, key geography, and military objectives. Also called MCOO (JP 2-01.3). Although not all inclusive, some specific aspects are— Friendly and enemy avenues of approach. Mobility corridors. Natural and constructed obstacles. Terrain mobility classifications. Key terrain. 2-253. An MCOO provides a basis for identifying mobility corridors and ground avenues of approach. An MCOO integrates all obstacles to vehicular movement—such as built-up areas, slope, soils, vegetation, and hydrology—into one overlay. It depicts areas that impede movement (severely restricted and restricted areas) and those areas where friendly and enemy forces can move unimpeded (unrestricted areas). The mission and a collaborative effort involving input from each staff section helps tailor the MCOO. Terrain is classified as severely restricted, restricted, and unrestricted. These terrain mobility classifications follow: Severely restricted terrain severely hinders or slows movement in combat formations without mobility enhancement. Mobility enhancement could consist of committing engineer assets to improve routes; deviating from doctrinal tactics, such as moving in columns instead of line formations; or maneuvering at speeds much lower than those preferred. Steep slopes and large or densely spaced obstacles with little or no supporting roads typically characterize severely
