There’s a FB link on the YouTube video.
“Look what we found out in the middle of the desert between Hackberry and Peach Springs, AZ”
Don’t know what direction it’s going, though...
Units training at Ft. Irwin (the National Training Center) rail-load their equipment for transport from home base to the NTC (Barstow, CA; junction of Interstate Highways 15 and 40), and back.
Without having seen the video, this is a plausible explanation for what is being described.
