What are nutritionally incomplete rations used in operational scenarios like long-range patrol called?

Nutritionally incomplete rations used in operational scenarios like long-range patrol are referred to as restricted rations. These are typically designed for situations where access to full nutrition is limited due to operational constraints. In the context of military operations, such rations are structured to provide necessary energy and sustain troops for extended periods without offering the complete range of nutrients that a balanced diet would normally include.

Restricted rations are especially useful in field conditions where carrying bulky supplies is impractical, and they focus on maximizing caloric intake while conserving weight and space. The name itself reflects their purpose – they are "restricted" in that they do not provide the complete nutritional profile that troops would ideally need, but they are still functional for maintaining energy levels during missions.

In contrast, supplemental rations are intended to enhance a soldier's dietary intake, special operation rations focus on the unique needs of special forces, and combat rations are typically designed to provide a more balanced nutritional profile to meet the requirements of combat scenarios. Understanding these distinctions helps in recognizing the specific application and context for each type of ration utilized in military operations.
