In combat, eating is often the only good thing about a day. When a soldier or marine sits down to warm up his M.R.E., he’s not being shot at, he’s not losing friends. It’s almost a ritual, and the very act of opening one of these packages suggests safety, however brief it may be. To a lot of the troops from many nations that I've met, mealtimes are the only thing to look forward to – other, perhaps, than going home. These are a selection of some of their Meals Ready to Eat, or MREs.
