Today I made a video explaining the difference between MREs and C-rations. I happened to have one box of 30-year-old C-rations in a closet. As it turns out it was a beans and franks meal with canned fruitcake for dessert.
I did not open any cans. The video is for an article on the chemistry of field for Chemical and Engineering News magazine. I will post the link when it is published on line. It should be May 3.
