The SUV jesse James was riding in, and shooting the Gau/Mini out of the top of is actually manufactured by a US company that creates custom vehicles for "executive protection" antipersonell/explosive hardened, bulletproof, full stock of crazy electronics... i cant remember the name of the company offhand, but thats actually an INPRODUCTION vehicle, ill see if i cant scrounge a link or a scanned article {which is where i gleaned that that thing hes shooting from is actually REAL}...
<edit> couldnt find the SYV in that vid but i did run across something similar with equal coolness....
It has all of the extras: three engines, a positive pressure air system with oxygen, halon extinguishers underneath, grenade launchers, the skin is electrified at 11000 volts, IR lighting, a 600 gallon water tank with a remote control water cannon (and separate skin irritant tank, if you so desire), and entirely bulletproof. It has a fridge too! It only gets 8 miles to the gallon, but isn't that better than the Suburban? Currently costs less than the monster Escalade on Ebay.
