The AAV is an armored assault amphibious full-tracked landing vehicle. The primary responsibility of the AAVs during an amphibious operation is to spearhead a beach assault. They disembark from ship and come ashore, carrying infantry and supplies to the area to provide a forced entry into the amphibious assault area for the surface assault element. Once the AAVs have landed, they can take on several different tasks: manning check points, Military Operations in Urban Terrain (MOUT) missions, escorting food convoys or mechanized patrol.
