Key Takeaways

  • The ten supply classes for the United States Army exist to help classify all the supplies used by the army personnel into logical categories. This is especially helpful in logistics and the organization of supplies across the board.

  • If you have familiarized yourself with all the classes, you will know who to reach out to in order to request supplies. You will also know the required processes involved in requesting supplies.
  • The supply sergeant is usually the person to approach when you need to request supplies. The relevant supply sergeant handles all supplies at the unit level. This individual’s job is to control the storage, issuing, safeguarding, and maintenance of all supplies. This applies across all levels of value, from the most inexpensive supply items to the most high-end, expensive ones.
  • If you need supplies, you should make a formal or informal request with the relevant supply sergeant. If the item is within reach and on-hand, it will be issued immediately and directly.

In that case, a request for the item in question will be sent by the supply sergeant through higher headquarters to requisition the required items. This is usually achieved through the Battalion S4 or the relevant Property Book Officer.
