In the army we have 24hr ration packs, everything you need to eat and it works out about 2000 calories. All sorts of menus and they come in a box that is numbered so you try to get a different number/menu each time. You can have a Vegetarian/Halal/Kosher etc. Now, the old menus always had a Yorkie bar in, it had "Not for civvies" across it. Use to love that, middle of the night in the middle of some s*** hole, normally very cold or wet or both, I would eat that, Just made you feel a bit better about yourself. Problem is chocolate does not travel to well in hot sandy places so we got a whole new ration pack designed for us. Out went the Yorkie, in came NUTS! Sometimes fruit and NUTS! Nuts do not make you feel better about yourself.
Fed up just writing about that, how could they swap chocolate for nuts!
