As regards packaging, Sopacko comes with all the same stuff, just in a clear bag. Menu C uses the original bag, but they're harder to find. The only ones worthwhile are those and two other brands.
If you see "MREs" for sale from other places, and the picture of it includes a "nutra fruit" bar, don't buy those...they're crap, with junk food in them, all salt and empty calories with almost no protein. Very low quality.
www.mreinfo.com will show you some more, explain the date codes, and even let you see what other countries eat for their rations.
I actually wish someone made a civilian version of the French RCIR, too. One thing they can do is cook, even with rations.
Main Dishes:
Sauté of rabbit
Alsatian pork stew
North African lamb stew

I mean...damn. Talk about camping with style. :)
