5 Limited Ground Observation. Limited ground observation may require the use of forward air controllers (airborne) (FAC(A)). (2) Rotary-Wing Aircraft. Attack helicopters provide a distinct advantage to the commander in MOUT. They can rapidly maneuver within the built-up area to attack a variety of targets. Urban structures offer ideal cover for attack helicopters. The ability to deliver PGMs, rockets, and 20 mm cannon fire makes attack helicopters valuable assets in reducing strongpoints, breaking up enemy concentrations, and providing suppressive fires for attacking forces. Attack helicopters also provide a highly manueverable antiarmor capability. (a) Attack Helicopter Fire Support During Offensive/Defensive Operations 1 Provide close air support in support of the commander’s scheme of maneuver 2 Provide suppression and/or destruction of enemy forces within buildings and strongpoints 3 Conduct counterattacks 4 Isolate the built-up area or objectives within the built-up area 5 Conduct armed reconnaissance and patrols. 6 Conduct rapid concentration of fires. 4106. Armored Vehicles a. Employment of Armored Vehicles. Tanks, LAVs, and AAVs are primarily mobility assets that function best in an unrestricted, mobile environment. However, these vehicles can play an important role inside the city by using their firepower in support of offensive and defensive operations. LAVs and AAVs highly are susceptible to armor-piercing rounds and manpacked antiarmor weapons. All vehicles are susceptible to top-attack munitions. Some of the fire support roles armored vehicles may provide include: Suppression and/or destruction of enemy forces within buildings and strongpoints (tanks/LAVs/AAVs) Provide machinegun suppression fires Reserve or counterattack suppression fires (tanks and/or AAVs) Creating entry/exit points in buildings Isolation of the built-up area or objectives within the built-up area (tanks/LAVs/AAVs) Military Operations on Urbanized Terrain 4-9
