Artillery-towing vehicle (LAVs/AAVs) Antiarmor fires Breaching obstacles in a direct fire mode. b. Special Consideration. The existence of waterways, canals, and rivers in and around urban areas can provide avenues of ingress into designated objective areas. If used in conjunction with supporting fires, smoke, and/or deception operations, AAVs can capitalize on their amphibious capability and make use of waterways previously viewed as obstacles. 4107. Antiarmor Weapons. Antiarmor weapons have more utility in the defense than in the offense. Their primary task is defeating enemy armor. Secondary tasks may involve blasting holes in structures and fortified positions. As with other weapons systems, antiarmor weapons are normally employed in a decentralized fashion at the small unit level. Enemy armor should be engaged in predetermined locations that afford the most advantage to the defender. Weapon positions should be selected that provide maximum range fires. TOWs and Dragons may be fired from an enclosed area if it is a sturdy ventilated structure of appropriate size. For a more detailed discussion of antiarmor weapons, see MCWP 3-15.5, Antiarmor Operations. 4108. Employment of Snipers a. General. Snipers are highly trained in field skills and marksmanship and can deliver long-range precision fire at selected targets from concealed positions. The method by which snipers are employed in urban warfare will be governed by the nature of the terrain/weather, number of snipers available, and whether the enemy employs snipers. A sniper can play an important role in MOUT. Employment of snipers influences the action by: Creating adverse psychological affects on the enemy by negating feelings of security Inflicting casualties on enemy leadership Enabling the infantry to seem to cover a large area, regardless of whether the terrain is physically occupied or not Detailing enemy positions and activity through the use of advanced optical equipment and observation techniques Controlling fire support Conducting reconnaissance in conjunction with their sniper role Disrupting enemy movement, observation, and infiltration, and negating the possibility of surprise.
