In the 1940s, K-rations were the portable foods that the American soldiers carried with them into combat. They weren't designed to be delicious, or even particularly healthy. The Army was more concerned with giving its soldiers the energy to keep fighting. And it had to be light enough to carry up mountains or hiking through jungles. The K-rations came in 3 different servings: breakfast, lunch (supper) and dinner. But most soldiers couldn't tell the difference.
And when you're starving, K-rations are the best tasting meals on earth.
