What type of items are classified as supply Class I?

Supply Class I items are classified as food and water. This classification is crucial in materiel management, particularly for military operations and field logistics, where sustenance is a top priority for maintaining personnel readiness and morale. Ensuring that troops have adequate access to food and clean water is essential for their health and performance.

The classification system is designed to categorize supplies based on their primary purpose and function in supporting operations. Class I specifically focuses on items that are necessary for basic life support, which includes not just the food itself but any necessary hydration resources. This makes it distinct from other supply classes that encompass different categories of items such as communications, petroleum products, or administrative supplies, which serve varying logistical and operational needs.
