The M51 was the companion vehicle to the M103 heavy tank. This video, oddly, gives us the tour, inside and out, of the major parts of this purpose-built vehicle mainly used by the Marines, and now located at the US Army's Armor and Cavalry Collection in Ft Benning, GA.
Thanks to the ACC and the Patreons for making the trip possible.
