drinking water, food, and first-aid supplies at each squad position. Other factors the company commander must consider are: • Resupply/pre-positioning of caches. • Casualty evacuation. • Firefighting/ventilation. (See FM 90-10-1.) • Security. k. Communications. To ensure adequate communications, redundant verbal and nonverbal communications are planned and checked. The company installs a wire net and develops a plan for pyrotechnic signals. Backup wire should be laid in case primary lines are cut by vehicles, fires, or the enemy. The commander also plans for the use of messengers throughout the village. L-15. DEFENSE OF A BLOCK OR GROUP OF BUILDINGS An Infantry company operating in urban terrain may have to defend a city block or group of buildings in a core periphery or residential area. The company conducts this operation in accordance with the battalion task force’s defensive scheme of maneuver. The operation should be coordinated with the action of security forces charged with delaying to the front of the company’s position. The defense should take advantage of the protection of buildings that dominate the avenues of approaches into the MBA. This mission differs from defense of a village in that it is more likely to be conducted completely on urban terrain, without surrounding open terrain that characterizes the defense of a village. An Infantry company is particularly well suited for this type of mission, since the fighting will require the enemy to move Infantry into the urban area in order to seize and control key terrain. Table L-2 describes the frontages that are normally occupied when defending on this type of terrain. The density of buildings, rubble, and street patterns will dictate the company’s frontage. UNIT

Table L-2. Approximate frontages and depths. Note: An average city block has a frontage of about 175 meters. These minimum figures apply in areas of dense, block type construction; multi-story buildings; and underground passages. The factors of METT-TC must be applied to the defense of buildings and frontages can be extended or reduced accordingly. a. Task and Purpose. A well-organized company defense in the urban area• Defeats the enemy’s attack on the streets and city blocks by using obstacles and fire. • Destroys the enemy by ambush and direct fire from prepared positions within defensible buildings. • Clears the enemy from footholds or remains in place for a counterattack.
