I wonder what it's mounted on, too. At first I thought some kind of infiltration/fast attack craft, which would be plausible given the camo, but now I'm not so sure. See the the photo to understand why. It looks kind of like some sort of armored vehicle, similar in roof configuration to the MBRL armed M-1992 BRDM, but without cabin windows and stuff... So, boat, new armored vehicle, or what?
