The Horch 1a was a light utility vehicle used by the Germans through WWII, though not as much as the Kubelwagen.
 In Game
In Call of Duty: United Offensive, the Horch is mainly used to transport troops. It can carry three passengers; a driver, a gunner and a passenger. It has a MG42 turret mounted on it, allowing it to be used against infantry. Make sure to stay away from tanks, unless you want to suffer a quick death.
