B-ration

The B-ration (officially Field Ration, Type B) 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 B-ration differs from other American alphabetized rations such as the A-ration, consisting of fresh food; C-ration, consisting of prepared wet food when A- and B-rations were 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.
