AA has been working with the G-Wagon for a couple of decades now, and unless you’re attacked by an actual army, you’re going to be okay. The doors and windows can stop a .357 with full metal jacket bullets at point-blank range, which is a level of protection NATO deems good enough for most mid-level diplomats. The sky's pretty much the limit, though, and while they do ask for a little more money, they don't ask questions if you need your vehicle IED-proofed.
