Humanitarian Daily Ration's (HDR) are designed to withstand extreme environmental conditions by design and are water proof.
Humanitarian Daily Rations, developed by the U.S. Department of Defense, are specifically designed to meet the nutritional needs of civilians in humanitarian crisis. One HDR provides the average daily needs of the civilian population with about 1,900-2,200 kcal and adequate protein, fat, and micronutrients.
Meals-Ready-to-Bat are based on American recipes and are designed to provide one meal three times a day (3,600 kcal). MREs contain fish and meat products, and there are over 25 different varieties.
