Different U.S. Army Classes of Supply 2024

Class I – Subsistence (food and drinking water)

Class I covers the essentials for survival: food and drinking water. It includes various ration assemblies that soldiers consume during missions. Fresh fruits and vegetables fall under this category. The primary goal of Class I is to ensure the sustenance and hydration of military personnel during operations.

Class II – Clothing and Equipment

Class II encompasses all clothing and personal equipment items. This class ensures soldiers have the necessary individual equipment for their missions. It includes items like tentage for shelter, organizational tool sets for maintenance tasks, hand tools, unclassified maps for navigation, and administrative and housekeeping supplies. Class II provides the tools and attire necessary for soldiers to function effectively and comfortably.

Class III – Petroleum, Oils, and Lubricants (POL)

Class III is crucial for the operation of machinery and vehicles in the military. It consists of gasoline, fuels, and various lubricants. Hydraulic and insulating oils are part of this class, as are bulk chemical products. Additionally, coolants, de-icing compounds, antifreeze compounds, and additives for petroleum and chemical products fall under Class III. This class ensures the smooth operation of equipment, keeping machinery and vehicles running efficiently during military operations.

Class IV – Construction and Barrier Materials

Class IV focuses on materials vital for constructing fortifications and barriers. These materials play a key role in providing security, establishing defensive positions, and supporting military engineering projects. Within this category, you’ll find items such as concertina wire for fencing, lumber for various constructions, sandbags for protection, and pickets for staking and support. In essence, Class IV ensures military personnel have the resources to build and fortify structures as needed.

Class V – Ammunition

Class V is all about firepower. This category houses all types of ammunition, ranging from small arms bullets to large artillery shells. It’s not just limited to conventional munitions; it also includes chemical, biological, radiological, and nuclear (CBRN) munitions. Ensuring a steady supply of Class V materials is crucial. Without it, the military’s ability to defend, attack, or deter adversaries becomes significantly limited.

Class VI – Personal Demand Items

Class VI caters to the personal needs of military personnel. These are items not necessarily critical for mission success but essential for morale and comfort. This class includes personal hygiene items, toiletries, and non-military sales items. By providing these personal demand items, the military ensures the well-being and mental health of its members, contributing to overall mission effectiveness.

Class VII – Major End Items

Class VII comprises the large equipment and machinery that the military uses in its operations. Think of tanks, launchers, mobile machine shops, and other vehicles. These are items that are complete in themselves and ready for their intended use. Their presence and operational readiness are essential for the military to effectively execute its missions. Ensuring a consistent supply and maintenance of Class VII items is of paramount importance.

Class VIII – Medica

The health and well-being of military personnel are of utmost importance, and that’s where Class VIII comes into play. This class covers all medical supplies, ensuring that soldiers receive the necessary medical care when injured or ill. It includes everything from bandages and medicines to more specialized equipment and repair parts specifically for medical devices. A well-stocked Class VIII supply ensures that the military can handle medical emergencies efficiently, keeping its personnel healthy and mission-ready.

Class IX – Repair Parts

Machinery and equipment are only as good as their operational status, and Class IX ensures they remain in top condition. This class is dedicated to the parts and kits required for the maintenance and repair of equipment. It spans across all levels of repair, from immediate field fixes to more extensive depot-level repairs. By maintaining a consistent supply of Class IX items, the military ensures that its equipment remains operational, reducing downtime and increasing mission effectiveness.

Class X – Material to Support Nonmilitary Programs

Class X stands out as it addresses needs beyond direct military operations. This class provides materials essential for nonmilitary programs, often related to humanitarian or development efforts. Such programs might include agriculture initiatives, economic development projects, or educational outreach. Class X supplies support the broader goals of the military when engaging with local communities, fostering goodwill, and contributing to the stabilization and reconstruction of regions. By facilitating such programs, Class X materials play a pivotal role in the military’s strategic engagements and its commitment to positive global impact.

Material to Support Nonmilitary Programs

While most of the Army Classes of Supply focus on direct military needs, there’s a unique category dedicated to supporting nonmilitary endeavors. This category, not specifically labeled as one of the standard classes (I through IX), emphasizes the military’s broader role in global community engagement.

Materials in this category drive initiatives like agriculture and economic development. Whether it’s providing tools for farming, infrastructure development resources, or supporting local trade and industry, these supplies play a critical role. By backing such projects, the military not only fulfills a humanitarian objective but also fosters relationships, builds trust, and lays the foundation for long-term regional stability. The provision of these materials underscores the military’s comprehensive approach to its missions, integrating defense with community development and diplomacy.

North Atlantic Treaty Organization (NATO) Classes of Supply

The North Atlantic Treaty Organization (NATO), while sharing some similarities with the U.S. Army’s classes of supply, uses its distinct classification system. Recognizing these classes provides insights into how this alliance ensures its logistical readiness. Let’s delve into the NATO Classes of Supply:

  1. Class I: Subsistence items, like food and forage, consumed uniformly by personnel or animals.
  2. Class II: Supplies determined by organizational tables, such as clothing, weapons, tools, spare parts, and vehicles.
  3. Class III: Petroleum, oil, and lubricants (excluding aviation use). Class IIIa specifies aviation fuel and lubricants.
  4. Class IV: Supplies not listed in initial issue tables, like fortification materials and extra Class II items.
  5. Class V: Ammunition, including explosives and chemical agents.
