XM808 was a proof of concept vehicle created without requirement by Lockheed Missile and Space. Three were built for the Army for testing for lunar operations, the fascinating armed and armored version is found today at the US Army Armor and Cavalry Collection, Ft Benning, GA.

Thanks to the ACC and the Patreons for making the trip possible.
