I feel like anyone who's been in the military in the past, what, 40 years, will know about the Jimmy Deans without any explanation, but it will be a mystery from anyone who served before that, or not at all.
So, sometimes you're in basic training or Airborne School or whatnot and you're out training so you can't go back to the DFAC to eat, and the Army can't be bothered to bring out hot food in sawdust boxes called Mermites. So what do you get? Not MREs - those cost the government like eight bucks, and have frankly too many calories for almost anything short of filling sandbags 16 hours a day. No, you get a shrink-wrapped tray with a can of sausage or tuna or meat paste, a can of Pringles, a juice box and some other similar shit, none of it remotely edible, and at least at one time made by the Jimmy Dean Sausage Company, a division of Tyson Foods, who were the low bidder.
One time in Iraq, we were out in the field for like a week building a combat outpost in Tal Abdah, which is in the middle of nowhere, even for Iraq. The BSB came out with some PLS flat racks full of HESCOs and concertina wire and whatnot and one flat rack full of pallets of hot bottled water ... and Jimmy Deans. We rat fucked them for the Pringles, ate nothing but crispy salted potato paste for a week, and left the rest for the cavalry that came out after we were done to occupy the place, and for the mice. The previous COP build hadn't gone well, and I think it was the Brigade Commander's way of punishing us.
