In military logistics, what do Class IV supplies typically include?

Class IV supplies in military logistics specifically refer to construction and barrier materials. This category includes items necessary for building, fortifying, and maintaining installations and defensive positions, such as lumber, concrete, sandbags, and wire. These supplies play a crucial role in enhancing operational readiness and ensuring that facilities can support various military functions.

While the other categories listed—fuel and lubricants, clothing and personnel gear, and medical supplies—are essential to military operations, they are classified under different supply classes. Fuel and lubricants fall under Class III, clothing and personnel gear are part of Class II, and medical supplies are categorized as Class VIII. Understanding these classifications is vital for effectively managing resources in military logistics.
