-COMMISSARY

Traditionally, military units provided most of the rations, uniforms, and other supplies needed by most military personnel. However, modern units often provide fewer items and many personnel must buy some items with their own funds. Personnel with families also must buy food, clothing, and other necessities for the family. This has created the need for modern commissary and “PX” (post exchange) buildings. In some cases, these buildings are similar to modern supermarkets.
