MRE also with waterMRE not only contains food to eat, but water also.
I propose that in order to prepare MRE you would not only insert food into the MRE packing unit, but water also.
Then if you eat MRE, you will not only satisfy your hunger, but thirst aswell.
It saves place in your pocket. It's more real. It make's sanse.
(why bother to make MRE, if you could carry a prepared food with you?)
