I spotted a fleet of non-US LC just outside Washington DC.
Interesting that you found these (not to far off I-95). My brother works there. They specialize in up armoring Cruisers, Hummers, Caddies, Suburbans, etc. for the Diplomatic fleet around the world. I got to do a mini tour when I was home. It was pretty impressive. Got to see an up armored hummer that hit an IED in the field and it was driven out of the kill zone. Lots of cool vehicles with run flat tires, armor, bullet proof glass, snorkels etc. A lot of interesting modifications with commo, satellites, and gps etc as well. All of these vehicles are shipped straight from the factory to VA where they are modified and shipped back out to locations all over the world. Wish I had some of the government money, I'd send my truck there.
