As of 2023, four types of Unitized Group Rations exist.
Heat & Serve 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 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).
A Option The
Unitized Group Ration – A (
UGR-A) is the successor to the A-ration, and consists of perishable entrées intended to be prepared in a field kitchen. The UGR-A is the only UGR with
frozen food, and requires
refrigeration to store and prepare. The UGR-A has 7 breakfast menus and 14 lunch/dinner menus. Each meal provides an average of 1,450 kcal. Each UGR-A module contains 50 meals, with each pallet holding 600 meals. UGR-A modules have a minimum shelf life of 9 months outside the
contiguous U.S. and 3 months within the contiguous U.S., at 80 °F (26.6 °C) for semi-perishable modules and 0 °F (-17.7 °C) for perishable modules.
A, Short Order The
Unitized Group Ration – A, Short Order (
UGR-A SO) consists of meals intended to supplement the UGR-A and expand available food options or feed larger groups, especially where alternate dining facilities or existing meal options are unavailable. Most UGR-A SO meals are based on
fast food,
pub food, and
finger food. The UGR-A SO has the same kilocalorie amount, storage, and minimum shelf life as the regular UGR-A. == Menus ==
