The K ration is an American emergency Meal Ready to Eat (MRE) from World War II that was produced en masse for use and export. It is barely tolerable and not exactly fulfilling for a day of intense fighting, but will keep a person alive when facing starvation. The US quickly lost interest in the K ration after WW2, well after hundreds of millions had already been produced. A large part of this huge surplus has landed in Oceanyka, and many companies still manufacture them.
