The Stryker is an 'Interim Armored Vehicle', intended to fill the capability gap between heavy and lethal, but not easily deployable vehicles (such as the M2 Bradley), and easily deployed, but lightly armed and protected vehicles (such as the Humvee). Its primary role is the rapid transportation and deployment on infantry, with increased speed and agility compared to heavier vehicles, at the cost of lighter armor.
The Stryker 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 "Stryker" seen in Aliens vs. Predator: Requiem is actually a visually-similar Omni International V-150-S prototype. The most obvious difference between the V-150-S and a real Stryker is the lack of a turret on the latter; instead, the Stryker's main .50 cal machine gun is housed in a remotely-operated cradle. The V-150-S also has a significant gap between the front and rear pairs of axles, whereas on the Stryker all four axles are spaced equidistantly. The V-150-S was used in the film because the production could not secure the use of a real Stryker from the US military.
