Military Operations on Urbanized Terrain (MOUT) — FM 90-10

Tactical doctrine stresses that urban combat operations are conducted only when required and that built-up areas are isolated and bypassed rather than risking a costly, time-consuming operation in this difficult environment. Adherence to these precepts, though valid, is becoming increasingly difficult as urban sprawl changes the face of the battlefield. The acronym MOUT (Military Operations on Urbanized Terrain) classifies those military actions planned and conducted on a terrain complex where manmade construction impacts on the tactical options available to commanders. Commanders must treat the elements of urban sprawl as terrain and know how this terrain affects the capabilities of their units and weapons. They must understand the advantages and disadvantages urbanization offers and its effects on tactical operations.
