This few years old now, but I think it marks and important change. It's good to see the U.S. Military is using all that science smarts for to invent something that's not used to kill/destroy/find people to kill/destroy.

Ladies and Gentlemen: The Indestructible Sandwich

"Capable of surviving airdrops, rough handling and extreme climates, and just about anything except a GI's jaws, the new "pocket" sandwich is designed to stay "fresh" for up to three years at 26 °C (about the temperature of a warm summer's day), or for six months at 38 °C (just over body temperature)."

Thanks, Science.
