The Jeep came about as the military required an all-purpose vehicle. Its performance in World War II was superb. The jeep could operate without strain from three to 60 miles per hour.
It could handle a forty degree slope, turn in a thirty foot circle, and tilt left or right on a fifty degree angle without tipping over. It would "go places where tankers quit and birds would go back exhausted." The jeep went up rocky mountains in Switzerland and moved snow off roads in Belgium. Although the tank had an influence on the war too, it could not go as many places as the jeep.
