Thanks to Len for the link!
According to the vid the star of this show is suppose to be the gun bunnies and the mortar they're firing.
In my mind its the M1163 Growler.
This is one of the rarest vehicles in the Marine Corps. Don't get me wrong, its out there to be scene but actual pics and videos of the thing are few and far between.
This vid satiated my curiosity. I wanted to take another look at it and I'm more convinced than ever that the MRZR is the right way to go.
