Amphibious vehicles are vehicles that can travel on both land and water. The two most common types of amphibious vehicles are AMTRACs and Utes. AMTRACs, which stands for amphibious tractor, are military vehicles that are designed to transport personnel and equipment from ship to shore. Utes, which stands for utility terrain vehicle, are civilian vehicles that are designed for recreational use in off-road environments. Both types of vehicles are equipped with special features that allow them to traverse both land and water.
