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. [1] IMPs provide 1,200–1,400 calories (5.0–5.9 MJ) per meal. [2]

Contents

Three IMPs (breakfast, lunch and dinner) provide approximately 3,600 calories (15 MJ), enough to nourish a soldier undergoing strenuous physical activity. The meals are precooked and can therefore be safely consumed either heated or unheated. Under ideal circumstances the entrees are generally consumed heated. There are meals available to Jews, Muslims, Hindus and vegetarians. [3]

In 2015 IMPs include a variety of items, such as pulled pork, poutine and beef jerky (above) IMP Jerky Front.JPG

Contents of the combat rations are subject to a three-year research and development cycle, where new meals are added, and some replaced. Every second year, new meals are field tested by three groups of 60 people drawn from each of the three Canadian Army brigades. In all, there are 21 meals available  seven breakfasts and 14 meals suitable as noon or evening meals. In addition to the main meal, each IMP contains assorted basics such as powdered coffee, protein and sports drink mixes, energy bars, trail mix, peanut butter, cereal, condiments, candy, chocolate, gum, a plastic spoon, a wet towelette and matches. [2]

Meals are packaged fully cooked and do not require cooking. While edible cold, when circumstances permit the ideal method of preparation is to cook the entrees either in a pressure cooker, heated on the standard issue Coleman stove, or by simply boiling the rations in its package in water. Another way to warm the meal when a stove is unavailable is by putting it in the pocket of a coat during winter. Chemical cooking pouches have also been issued, allowing for flameless meal heating. Other items can also be improved by boiling or adding water, such as packages of soup, rice, powdered drinks and even the prepackaged bread, which is dense and can be softened by exposure to the pressure cooker.

Another technique developed by soldiers in the field is putting the package in the grill covering the exhaust on many armoured vehicles, and on radiators of wheeled vehicles. Some armoured vehicles come with a built-in pressure cooker.

History

The IMPs appeared in the Canadian Forces in the 1980s, replacing early canned rations (Individual Ration Pack (IRP), Canadian Army Mess Tin Ration, Compo rations). The main menu items of the IMP are "boil in a bag" (known as a "retort pouch") and require less preparation time and equipment than the previous canned rations. Another stated advantage is that preparation using retort pouches can be done using less heat, reducing the impact on the taste of the food. [2]

Preparation and cooking

For IMPs from 2019 and beforehand, the main entrée and the dessert portion are contained in retort pouches, which are then packaged in cardboard boxes. These cardboard boxes are positioned inside the IMP package on the outer sides, sandwiching the other contents, so the IMP itself looks like it is entirely contained within a cardboard box inside the outer foil-lined paper bag. IMPs are usually "stripped" before field use by removing the cumbersome packaging and discarding extraneous elements individual soldiers do not wish to carry with them, such as the cardboard boxes containing the main entrée and dessert, and any condiments that an individual soldier may not personally use. As of 2020 new packaging has been created to help with usability and edibility. Notably, the external packaging is resealable and waterproof. Inside, the cardboard boxes have been removed to reduce weight, and the entrée and the dessert pouches have been strengthened, and a resealable beverage pouch has been provided for cold (powdered beverages). It is also not uncommon to see service members drinking hot drinks (coffees, teas, hot chocolates) out the resealable pouch, even though it is not recommended. The new method of heating has greatly improved over the previous options. The member simply puts their meal packet into a flameless ration heater. The chemical reaction generates enough heat to ensure a hot meal. [3]

Other rations

Other types of rations are used by the Canadian Forces, notably fresh rations, or cooked meals provided directly from the kitchen or by haybox. There are also patrol packs, which are small high-protein snack-type foods (such as beef jerky or shredded cheese) and boxed lunches (consisting of assorted sandwiches, juice, fruit, pasta and a dessert) provided for soldiers to consume in situations in which meal preparation nor the delivery of haybox style fresh rations are not possible, such as travelling for training within Canada or spending the day on a shooting range. The IMP is intended to be issued when fresh rations are not possible, they can also be consumed as emergency rations, unheated.

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.

<span class="mw-page-title-main">Haybox</span>

A haybox, straw box, fireless cooker, insulation cooker, wonder oven, self-cooking apparatus, norwegian cooker or retained-heat cooker is a cooker that utilizes the heat of the food being cooked to complete the cooking process.

Generally, it takes three times the normal cooking time to cook food in a haybox.

<span class="mw-page-title-main">Military rations</span> Goods, usually food, given to military personnel

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.

<span class="mw-page-title-main">LRP ration</span> U.S. military freeze-dried dehydrated field ration

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).

<span class="mw-page-title-main">Self-heating food packaging</span> Food packaging that uses exothermic reactions to heat its contents

Self-heating food packaging is active packaging with the ability to heat food contents without external heat sources or power, usually using an exothermic chemical reaction. Packets can also be self-cooling. These packages are useful for military operations, during natural disasters, or whenever conventional cooking is not available. They are often used for military field rations, camping food, instant food, or other types of food intended for preparation where proper cooking facilities or methods are unavailable or less ideal.

<span class="mw-page-title-main">Camping food</span> Food designed for camping and backpacking

Camping food is food brought on or designed for camping, hiking, and backpacking trips. The term also encompasses ingredients that can be used to make said foods. The primary differences relate to campers' and backpackers' special needs for foods that have appropriate cooking time, perishability, weight, and nutritional content. To address these needs, camping food is often made up of freeze-dried, dehydrated, pre-cooked, pre-prepared, or otherwise preserved foods that can last extended periods.

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.
