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 alongside humanitarian daily rations during natural disasters and wars.https://www.ucl.ac.uk/rdr/teaching/acc-risk-disaster-reduction/mres

The MRE replaced the canned Meal, Combat, Individual (MCI) in 1981.Mason, V.C., Meyer, A.V., and Klicka, M.V., Summary of Operational Rations, Natick, MA: U.S. Army Natick Research & Development Laboratory Technical Report TR-82/013 (June 1982): The MRE was officially type-classified for adoption in 1975 but due to budget cuts was not officially placed into production until 1981; stocks of the MCI continued to be issued until exhausted. Its garrison ration and group ration equivalent is the Unitized Group Ration (UGR), its in-combat and mobile equivalent is the Close Combat Assault Ration (CCAR), and its long-range and cold weather equivalents are the Long Range Patrol (LRP) and Meal, Cold Weather (MCW) respectively.

History

Predecessors

The first American military ration established by a Congressional Resolution, during the Revolutionary War, consisted of enough food to feed a man for one day, mostly beef, peas, and rice.General Orders, 8 August 1775 |access-date=March 2022 | url = https://founders.archives.gov/documents/Washington/03-01-02-0173 During the Civil War, the U.S. military moved toward canned goods. Later, self-contained kits were issued as a whole ration and contained canned meat, bread, coffee, sugar and salt. During World War I, canned meats were replaced with lightweight preserved meats (salted or dried) to save weight and allow more rations to be carried by soldiers on foot. At the beginning of World War II, a number of new field rations were introduced, including the Mountain ration and the Jungle ration. Cost-cutting measures by Quartermaster Command officials during the latter part of World War II and the Korean War again saw the predominance of heavy canned C-rations issued to troops, regardless of operating environment or mission.Kearny, Cresson H. (Major), Jungle Snafus ... And Remedies, Oregon Institute (1996), pp. 286–291 During World War II, over 100 million cans of Spam were sent to the Pacific. The use of canned wet rations continued through the Vietnam War, with the improved MCI.

During the Vietnam War, problems with the canned MCI rations become apparent. MCI cans were heavy and bulky; they could not fit easily in a uniform pocket and could even cause injury. The cans could also corrode in the tropical environment and cause the food to spoil. After the food was consumed, the empty cans were difficult to dispose of; the littered cans were sometimes fashioned into booby traps by the enemy. Finally, the MCI rations had an estimated shelf life of 24 months at , which was found to be inadequate as supply was often interrupted by weather and enemy activity.

Introduction

After repeated experiences with providing prepared rations to soldiers dating from before World War II, Pentagon officials ultimately realized that simply providing a nutritionally balanced meal in the field was not adequate. Service members in various geographic regions and combat situations often required different subsets of ingredients for food to be considered palatable over long periods. Catering to individual tastes and preferences would encourage service members to actually consume the whole ration and its nutrition. Most importantly, the use of specialized forces in extreme environments and the necessity of carrying increasingly heavy field loads while on foot during long missions required significantly lighter alternatives to standard canned wet rations.

In 1963, the DoD began developing the "Meal, Ready to Eat", a ration that would rely on modern food preparation and packaging technology to create a lighter replacement for the canned MCI. In 1966, this led to the Long Range Patrol, or LRP ration, a dehydrated meal stored in a waterproof canvas pouch. As with the Jungle ration, its expense compared to canned wet rations, as well as the costs of stocking and storing a specialized field ration, led to its limited usage and repeated attempts at discontinuance by Quartermaster Command officials.

Early MRE prototypes that involved freeze-dried and dehydrated foods were developed under Abdul Rahman, who later received the Meritorious Civilian Service Award for his work. Further work was needed to develop a ration that did not require re-hydration (thus not requiring additional preparation time and water). Further effort, led by Dr. Rauno A. Lampi, Chief of Food Systems Equipment Division at the Natick Soldier Research, Development and Engineering Center, concentrated on the refinement of the retort pouch to contain a wet ration with a three-to-ten year shelf life that could be easily shipped, carried in the field, opened and consumed straight out of the package if necessary with no further heat or water. The resulting MRE went into special issue starting in 1981 and standard issue in 1986, using a limited menu of twelve entrées.

Ongoing development

The MRE has been in continuous development since its introduction.

After the introduction of the MRE, service members often heated the food by boiling them in a canteen cup over a lit fuel source. This was slow, especially in cold weather. It also produced a visible flame that was undesirable at night. Service members strongly desired a more convenient way to heat the food. Between 1988 and 1989, development and testing was conducted for a new flameless ration heater. In 1990, the Flameless Ration Heater (FRH) was introduced. Service members activate a chemical reaction with a few ounces of water, which produces an exothermic reaction. An FRH was included with each meal beginning with the MRE XIII in 1993.

In an array of field tests and surveys, service members requested more entrée options and larger serving sizes. By 1994, commercial-like graphics were added to make the packets more user-friendly and appealing, while biodegradable materials were introduced for inedible components, such as spoons and napkins. The number of main dishes expanded to 16 by 1996 (including vegetarian options), 20 by 1997 and 24 by 1998. As of 2023, the system includes 24 entrées, and more than 150 additional items. The variety allows service members to trade them in order to find something palatable for various cultures and geographical regions.

The ration originally came in a dark brown outer bag from 1981 to 1995 because it was designed for service in the temperate forests and plains of central Europe. It was replaced in 1996 with a tan outer bag that was better suited for service in the deserts of the Middle East. By 2000, a bean burrito main dish was introduced. In 2006, "Beverage Bags" were introduced to the MRE, as service members have begun to depend more on hydration packs than on canteens, thus denying them the use of the metal canteen cups (shaped to fit in a canteen pouch with the canteen) for mixing powdered beverages. In addition to having measuring marks to indicate levels of liquid for precise measurement, they can be sealed and placed inside the flameless heater.

Most recently, MREs have been developed using the Dietary Reference Intake, created by the Institute of Medicine (IOM). The IOM indicated service members (who were classified as highly active men between the ages of 18 and 30) typically burn about 4,200 Calories (kcal) a day, but tended to only consume about 2,400 Calories a day during combat, entering a negative energy balance. This imbalance occurs when service members fail to consume full portions of their rations.Institute of Medicine, Dietary Reference Intake Although manipulations to the food items and distribution of macronutrients to help boost the amount of kilocalories per MRE have been made, more studies are showing many service members still do not meet today's standards of daily consumption, often trading and discarding portions of the ration. Researchers continue to study the habits and eating preferences of service members, making constant changes that encourage service members to eat the entire meal and thus get full nutritional value. A small randomized controlled trial from 2017 confirms the nutritional balance of MRE eaten-in-whole using blood tests.

The military has experimented with new assault ration prototypes, such as the First Strike Ration and the HOOAH! Bar, designed with elite or specialized forces in mind. Lighter than the typical MRE, they require no preparation and allow service members to eat them while traveling.Institute of Medicine (U.S.). Committee on Optimization of Nutrient Composition of Military Rations for Short-Term, High-Stress Situations, Nutrient composition of rations for short-term, high-intensity combat operations pp. 15–27 In July 2009, 6,300 dairy shake packets of varying flavors were recalled due to evidence of Salmonella contamination.

Requirements

Each meal provides about . They are intended to be eaten for a maximum of 21 days (the assumption is that logistics units can provide fresh food rations by then), and have a minimum shelf life of three years (depending on storage conditions).

Packaging requirements are strict. MREs must be able to withstand parachute drops from , and non-parachute drops of . The packaging is required to maintain a minimum shelf life of three and a half years at , nine months at , and short durations from to must be sustainable. New forms of packaging are being considered to better meet these requirements including the use of zein to replace the foil, which can be easily punctured, conducts heat, and is reflective (which may give away a servicemember's position).

Each MRE weighs , depending on the menu. Since MREs contain water in the food, they weigh more than freeze-dried meals providing equivalent calories.

Resale status As a result of earlier unauthorized sales to civilians, the Department of Defense requires that "U.S. Government Property, Commercial Resale is Unlawful" be printed on each case of MREs. The warning is only intended for service members, as there are no laws that forbid the resale of MREs by civilians. Although the government has attempted to discourage sellers from selling MREs, auction sites such as eBay have continued to allow auctions of the MREs because the Department of Defense has been unable to provide any regulations or laws specifically outlawing the practice. According to a spokesman for eBay, "until a law is passed saying you can't sell these things, we're not going to stop them from being sold on the site." Therefore, while MREs are not prima facie contraband, the procurement and sale of MREs by military personnel for personal profit is illegal under the Uniform Code of Military Justice Article 108. As a result, MREs found for sale outside reputable vendors often fall into a grey market where the question of how it entered civilian hands (through theft/legitimate means) and/or its quality may be unknown.

An investigation conducted in 2006 on behalf of the U.S. Government Accountability Office (GAO) determined multiple instances where sellers on eBay may have improperly obtained MREs and sold them to the public for private gain. As military MREs are procured at taxpayers' expense, they are intended to be consumed by individuals from authorized organizations and activities. Consequently, "if military MREs are sold to the general public on eBay, then they are clearly not reaching their intended recipients and represent a waste of taxpayer dollars and possible criminal activity." Further, MREs found on eBay are typically older and closer to their expiration date, having been sourced in "neighborhood yard sales" and "Marine base dumpsters".
