Which class of supply is associated with Construction Materials?

• A. Class I
• B. Class II
• C. Class IX
• D. Class IV - Construction Materials

Answer: (D)

In military logistics, items are grouped by how they’re used and procured, so each class covers a distinct category. Construction materials are those bulky, durable items used to build and maintain facilities, roads, and infrastructure, which fits the dedicated category for construction-related needs. That class encompasses things like cement, lumber, steel, piping, and hardware—materials you’d use on construction projects or to repair and upgrade facilities. Other classes focus on different needs: subsistence items for food, clothing and individual equipment, and repair parts for maintenance of weapon systems and equipment. Because construction materials are defined under the category for building and infrastructure needs, they belong to Class IV.
