The A-ration (officially Field Ration, Type A) is a United States military ration consisting of fresh, refrigerated, or frozen foods. A-rations may be served in dining facilities, prepared in the field using field kitchens, or prepared at a fixed facility and transported to field locations in containers.[1] Its modern successor is the Unitized Group Ration – A (UGR-A), which combines multiple types of rations, including the A-ration, under one unified system.[2]
The A-ration differs from other U.S. alphabetized rations such as the B-ration, consisting of canned or preserved food; C-ration, consisting of prepared wet food when A- and B-rations are not available; D-ration, consisting of military chocolate; K-ration, consisting of three balanced meals; and emergency rations, intended for emergencies when other food or rations are unavailable.[3]
Unitized Group Ration A
A-rations today may include the Unitized Group Ration – A, a hybrid meal kit designed to feed a group of 50 people for one meal. The UGR-A has several different varieties, including a tray-based heat and serve (T-rat) form, heated by hot water immersion when a field kitchen is not available,[4] or the express form, with a self-heating module and disposable accessories.[5] The UGR-A is used to sustain military personnel during worldwide operations that allow organized food service facilities.
The UGR-A includes perishable/frozen type entrees (A-rations) along with commercial-type components and perishable/frozen type entrees to provide the luxury of an A-ration meal in the field, configured into individual meal modules for ease of ordering, distribution, and preparation. The UGR-A has at least 9 months shelf life (at 80°F or 27°C for semi-perishable modules and at 0°F or −18°C for perishable modules).[6]
Website on Military Nutrition Research – This website documents more than a century of scientific inquiry conducted by, for, and about the U.S. military to promote and sustain the nutritional health of military personnel and citizens alike.
The Meal, Ready-to-Eat (MRE) is a self-contained individual United States military ration used by the United States Armed Forces and Department of Defense. It is intended for use by American service members in combat or field conditions where other food is not available. MREs have also been distributed to civilians as humanitarian daily rations during natural disasters and wars.
The C-ration was a United States military ration consisting of prepared, canned wet foods. They were intended to be served when fresh or packaged unprepared food was unavailable, and survival rations were insufficient. It was replaced by the similar Meal, Combat, Individual (MCI) in 1958; its modern successor is the Meal, Ready-to-Eat (MRE).
United States military ration refers to the military rations provided to sustain United States Armed Forces service members, including field rations and garrison rations, and the military nutrition research conducted in relation to military food. U.S. military rations are often made for quick distribution, preparation, and eating in the field and tend to have long storage times in adverse conditions due to being thickly packaged or shelf-stable.
The K-ration was a United States military ration consisting of three separately boxed meal units: breakfast, dinner, and supper. It was originally intended as an individually packaged daily ration for issue to airborne troops, tank crews, motorcycle couriers, and other mobile forces for short durations.
Imperial Japanese rations were the field rations issued by Imperial Japan in World War II, and which reflected the culture of the Japanese military. Rations had to be stout, durable, simple, sturdy and had to survive without refrigeration for long periods of time. Typically each ration was served in the field in canned food boxes, and cooked near the battlefield. The mess tin was known as a han-gou.
Humanitarian daily rations (HDRs) are food rations manufactured in the United States intended to be supplied to civilians and other non-military personnel in humanitarian crises. Each is intended to serve as a single person's full daily food supply, and contains somewhat over 2,200 calories (9,200 kJ). They have shelf-lives of about 3 years, and their contents are designed to be acceptable to a variety of religious and ethnic groups. The meals cost approximately one-fifth of the cost of a Meal, Ready-to-Eat (MRE), or US$4.70 in 2012. The rations were first used in Bosnia in 1993 as part of Operation Provide Promise.
A field ration is a type of prepackaged military ration designed to be easily and quickly prepared and consumed in the field, in combat, at the front line, or where eating facilities are otherwise unavailable. Field rations are primarily used by military forces, though they are also sometimes distributed to civilians as part of humanitarian aid and emergency management. They differ from garrison rations and field kitchen provisions, which are intended for where proper meals can be supplied and prepared with relative ease and safety, such as in the rear where logistics are steady and fresh food can be supplied. They are similar to, but distinct from, other purpose-designed long-lasting types of food or rations such as emergency rations, humanitarian daily rations, and camping food.
The Individual Meal Pack or IMP is one type of field ration used by the Canadian Forces. The IMP is designed so that a continuous diet provides all the nutrition needed to sustain a service-person in the field. The IMP meets Canada's nutrition requirements, with the exception of calcium and folic acid, which are not significant if the consumption period of rations is less than 30 (consecutive) days. IMPs provide 1,200–1,400 calories (5.0–5.9 MJ) per meal.
A garrison ration is a type of military ration. Usually distinct from field rations, the term has varying meanings, but generally refers to either rations issued to personnel at a camp, installation, or other garrison; allowance allotted to personnel to purchase goods or rations sold in a garrison; the rations purchased with the aforementioned allowance; or a type of issued ration.
The Mountain Ration was a United States military ration developed for use by U.S. troops operating in high-altitude or mountainous regions of the European theatre of World War II.
Military rations, operational rations, or military provisions are goods issued to sustain the needs of military personnel. As their name suggests, military rations have historically been, and often still are, subject to rationing, with each individual receiving specific amounts from available supplies. Military-issued goods and the rationing of such goods has existed since the beginnings of organized warfare.
A field kitchen is a kitchen used primarily by militaries to provide hot food to troops near the front line or in temporary encampments. Designed to be easily and quickly moved, they are usually mobile kitchens or mobile canteens, though static and tent-based field kitchens exist and are widely used.
The Food Packet, Long Range Patrol was a freeze-dried dehydrated United States military ration used by the Department of Defense. Developed in 1964 and intended for wide adoption during the Vietnam War, its use was eventually limited to American special operations forces during long-range reconnaissance patrols, where bulky canned Meal, Combat, Individual (MCI) rations proved too heavy for extended missions on foot. The LRP had a cold-weather warfare equivalent, the Ration, Cold Weather (RCW).
The Meal, Combat, Individual (MCI) was a United States military ration of canned and preserved food, issued from 1958 to 1980. It replaced the earlier C-ration, which it was so similar to that it was often nicknamed the "C-ration", despite the term never being used officially. The MCI was eventually replaced by the Meal, Ready-to-Eat (MRE).
The B-ration was a United States military ration consisting of packaged and preserved food intended to be prepared in field kitchens by cooks. Its modern successor is the Unitized Group Ration – M (UGR-M), which combines multiple types of rations, including the B-ration, under one unified system.
The history of military nutrition in the United States can be roughly divided into seven historical eras, from the founding of the country to the present day, based on advances in food research technology and methodologies for the improvement of the overall health and nutritional status of U.S. military service members. Through the research and guidance of medical and military professionals, rations and packaging have been consistently and dramatically improved.
Military nutrition is the field and study of food, diet, and nutrition in the military. It generally covers and refers to military rations and nutrition in military organizations and environments.
Prison food is the term for meals served to prisoners while incarcerated in correctional institutions. While some prisons prepare their own food, many use staff from on-site catering companies. Some prisons support the dietary requirements of specific religions, as well as vegetarianism. Prisoners will typically receive a series of standard meals per day from the prison, but in many prisons they can supplement their diets by purchasing additional foods, including snacks and desserts, at the prison commissary with money earned from working in the prison or sent by family and friends.
The Unitized Group Ration (UGR) is a United States military ration used by the United States Armed Forces and Department of Defense (DoD). It is intended to sustain groups of American service members with access to a field kitchen, serving as a field ration and a garrison ration. It is the modern successor to several older alphabetized rations—namely the A-ration, B-ration, and T-ration—combining them under a single unified system. UGRs are designed to meet the Military Daily Recommended Allowance when averaged over a 5 to 10 day period, with each meal providing between 1,300 and 1,450 kcal.
