The Scouter is a drivable vehicle in Fallout Tactics: Brotherhood of Steel.
The Scouter was built by the Eastern Brotherhood of Steel using old VW parts. It's great for quick reconnaissance work. The cockpit is almost entirely enclosed, although the armor is really only effective against light weapons. It holds two men, but has a reasonable cargo capacity.
It is found by the Warrior in Jefferson, where it was left because its owners, the Brotherhood scouts, were already dead.
The Scouter resembles the World War II era German Schwimmwagen, which is essentially an amphibious variant of the German Kübelwagen, another WWII era German vehicle.
Scouter appears only in Fallout Tactics.
