The C-ration (officially Field Ration, Type C) was a United States military ration consisting of prepared, canned wet foods. They were intended to be served when fresh or packaged unprepared food was unavailable, and survival rations were insufficient.[1] It was replaced by the similar Meal, Combat, Individual (MCI) in 1958; its modern successor is the Meal, Ready-to-Eat (MRE).
Development of the C-ration began in 1938. The first rations were field-tested in 1940, and wide-scale adoption followed soon after. Operational conditions often caused the C-ration to be standardized for field issue regardless of environmental suitability or weight limitations. Though the C-ration was replaced in 1958, the new MCI was very similar to the C-ration, and was indeed still nicknamed the "C-ration" until its replacement by the MRE in the late 1970s.[2][3][4]
The C-ration differs from other American alphabetized rations such as the A-ration, consisting of fresh food; B-ration, consisting of packaged, unprepared food; 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.[5]
