The Amphibious Assault Vehicle (AAV) is a military vehicle designed to transport troops and equipment from sea to land. It can operate on both water and land, making it essential for amphibious operations. The AAV is equipped with tracks for mobility on land and a hull that allows it to float and navigate through water. These vehicles are typically used by the United States Marine Corps and can carry up to 21 Marines along with their gear. The AAV is armed with a machine gun for defense and has a robust design to withstand various combat conditions.
