Classes of supply
The United States Army divides supplies into ten Classes of Supply. The North Atlantic Treaty Organisation (NATO) uses only the first five, which NATO allies have agreed to supply to one another based on a NATO Standardization Agreement (STANAG). The other classes of supply remain in national hands.
