Unitized Group Ration
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.
The UGR was introduced in 1999, and is currently known to be used by the U.S. Army, U.S. Marine Corps, U.S. Air Force, and National Guard. The U.S. Navy also reportedly uses the UGR for disembarked operations, using the Navy Standard Core Menu (NSCM) aboard naval vessels.
The UGR's individual field and combat equivalent is the better-known Meal, Ready-to-Eat (MRE), with the First Strike Ration (FSR), Long Range Patrol (LRP), and Meal, Cold Weather (MCW) serving as specialized field equivalents.
Prior to the UGR's implementation, the U.S. military had several different types of rations used to feed service members in the rear or out of combat. Among them were the A-ration, consisting of fresh, refrigerated, or frozen food prepared in a kitchen and served in a mess, dining facility, or elsewhere; the B-ration, consisting of packaged, preserved foods prepared in a field kitchen; and the T-ration, a semi-perishable meal packaged, heated, and served in a tray pack similar to frozen meals; among others.
However, this created issues for military cooks, who "had to order an average of 34 separate items for each meal, and could only hope that they arrived when needed", forcing them to manage logistics and administrative functions instead of solely food preparation. Around 1995, the U.S. military launched a modernization program to resolve this issue while also increasing the quality and decreasing the cost of existing rations. Research was headed by the U.S. Army Natick Soldier Research, Development and Engineering Center and the U.S. Army Quartermaster Center and School. In an effort to simplify logistics and ensure all necessary ingredients were provided, the UGR was created in 1999, combining elements and offerings of the A-ration, B-ration, T-ration, and commercial items.
The UGR was initially trialed with the Army, with their first shipments received around 2000; the Air Force, Marine Corps, and Navy also began receiving UGRs at unspecified dates. The UGR-E was introduced in 2006. The UGR-B was phased out and replaced by the mostly similar UGR-M at an unspecified date.
As of 2023, four types of Unitized Group Rations exist.
The Unitized Group Ration – Heat & Serve (UGR-H&S) is the successor to the T-ration, and consists of precooked, shelf-stable tray pack entrées. The UGR-H&S is hermetically sealed and can be prepared using a tray ration heater or by immersing it in boiling water, ready to serve in 30 to 45 minutes. The UGR-H&S has an offering of 5 breakfast menus and 10 lunch/dinner menus; each meal provides an average of 1,450 kcal. Each UGR-H&S module contains 50 meals, with each pallet holding 400 meals. UGR-H&S modules have a minimum shelf life of 18 months at 80 °F (26.6 °C).
