Iron ration, also known as emergency ration, is a term used to describe the ration provided to soldiers during a situation of food scarcity. It is a term typically associated with the military, particularly during periods of conflict or difficult terrain. There are several synonyms for iron ration, including field ration, combat ration, survival ration, and emergency food. These terms all refer to a pre-packaged and easily transportable ration intended to provide essential nutrients during periods when supply lines are disrupted, such as during a natural disaster or in isolated locations. Regardless of the terminology used, the essential purpose of these rations is to ensure that soldiers have access to essential nutrients when traditional food sources are limited or non-existent.
