As promised here I am to eat an authentic brown bag MRE. Going by the info on MREinfo.com #3 Chicken Stew could have been produced any time between 1988 and 1995, but unfortunately I had to settle for 1995 when I opened it up and checked out the date codes on the meal items.
This review was conducted with my good friend Matt. Unfortunately I didn't have a third person to zoom the camera so some of the items are a bit hard to see. Still, you're not missing much, all the packaging details are pretty standard.
The MRE itself was provided by another friend who recovered it from his parent's house when they were moving.
