Military Operations on Urban Terrain (MOUT)

[Elvis]

The United States military term for urban warfare is Military Operations on Urban Terrain (MOUT). The British military term is FIBUA (Fighting in Built-Up Areas), although it has been called OBUA (Operations in Built-Up Areas) and, unofficially, FISH (Fighting in Someone's House). The term FOFO (Fighting in Fortified Objectives) refers to clearing enemy personnel from narrow and entrenched places like bunkers, trenches and strongholds; the dismantling of mines and wires; and the securing of footholds in enemy areas.
