yup...a few of us got together a while back and ordered some of the "taste-alikes" from one of the survival suppliers...the mil guys with us said they were the same thing, for all intents and purposes. same/similar calorie count, "food" content, plug ya up and make ya stinky, etc...
we got ours in boxes from cheaper than dirt (maybe it's "cheap as dirt"?)...be warned, once those guys get your mailing address youll get catalogs offering everything from "fantasy sword replicas" to survival gear for the day when the reds invade, or when the atf attacks your splinter cell's bunker, whichever comes first.
...tho they did send me a little spring loaded plastic pellet gun that resulted in quite a bit of carnage around the apartment :elkgrin: ...
