  History
  During World War Two, many prototypes were already developed for a ton jeep, which was still significantly lighter and more compact than the U.S. Army's lightest, all-terrain, all-purpose vehicle at the time, the Willys ton Jeep. They were intended for transport in small (glider) aircraft and such, but none went into production. However, after the war, a self-taught engineer, pilot, and auto racer, Ben F. Gregory, conceived a mini-jeep design and built a successful prototype, later named the "MM-100".
