The LAV-25 (Light Armored Vehicle) is an eight-wheeled amphibious armored reconnaissance vehicle used by the United States Marine Corps. It was built by General Dynamics Land Systems Canada and is based on the Swiss MOWAG Piranha I 8×8 family of armored fighting vehicles. It entered service with the Marines in 1983.
