Stryker [SEP] Introduction
The ICV (Infantry Carrier Vehicle) Stryker is a family of eight-wheeled armored fighting vehicles derived from the Canadian LAV III. 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 unrelated U.S. soldiers 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.
