Which of the following is included in supply inventories?

• A. Environmental controls inventory
• B. Training inventory
• C. Asset tracking inventory
• D. Sensitive item inventory

Answer: (D)

Supply inventories are intended to track items that require careful custody and strict accountability. The one category that fits this description is sensitive item inventory, which covers items that demand heightened security, strict handling procedures, and regulated storage—such as weapons, ammunition, and other controlled materials. Keeping a record of these items ensures proper authorization, custody, issue, and return, and helps prevent loss or misuse.

Environmental controls relate to equipment used to maintain storage conditions, not items that normally require the same level of accountability. Training inventory covers training aids and materials, which are important but managed differently from supply items. Asset tracking inventory refers to the system used to monitor all assets, not a specific item category, so it isn’t the item type included in supply inventories in the same sense.
