Various US items in my collection
US K-Rations
K-ration was adopted for use in 1942. The components of the K-ration was designed for only a few days use under assault conditions, the demands of war meant that soldiers often ate them for days or even weeks, At the height of the war in 1944, over 105 million of these rations were produced.
Early boxes were plain brown card, the packaging changed in 1944 to a coloured design to make it easier for soldiers to quickly select the meal, brown for breakfast, green for supper, and blue for dinner. Within these coloured boxes the meal was contained in a plain box, this was twice dipped in wax, after the contents were inserted and the box was sealed, in order to keep the contents waterproof.
