A combat ration is a type of pre-packaged food designed for military personnel to consume during operations. These rations are lightweight, durable, and provide essential nutrients to sustain soldiers in the field. They are often designed to withstand extreme conditions and have a long shelf life. There are various types of combat rations, such as the Meal, Ready-to-Eat (MRE) used by the U.S. military and the Operational Ration Pack (ORP) used by the British Army. These meals typically include a main course, side dishes, snacks, and beverages, ensuring that soldiers receive adequate energy and nutrition while on duty.
