The IAV (Interim Armored Vehicle) Stryker is a family of eight-wheeled, armored fighting vehicles derived from the Canadian LAV III and based on the Swiss Piranha III 8×8. Stryker vehicles are produced by General Dynamics Land Systems for the United States Army. It has 4-wheel drive (8×4) and can be switched to all-wheel drive (8×8).
The vehicle is named for two American servicemen who posthumously received the Medal of Honor: Private First Class Stuart S. Stryker, who died in World War II, and Specialist Four Robert F. Stryker, who died in the Vietnam War.
The M1128 Mobile Gun System is an eight-wheeled armored car of the Stryker armored fighting vehicle family, mounting a 105 mm tank gun, based on the Canadian LAV III light-armored vehicle manufactured by General Dynamics Canada. It is in service with the United States and was also being considered for adoption by several other countries.
