Any tank nuts here? WW1, WW2 Korea, Vietnam?

Not a tank but they just received these at the local National Guard.

I was wondering what the heck is with the slammed suspension on these? Here's a small clip of what they're all about.

I suspect that is an air ride suspension. I wonder if it could be self-sealing regarding small arms fire.
Need to secure that empty MG mount before they make their next video.
