What type of inventory involves a physical count of all items under the same COG or FSC?

The type of inventory that involves a physical count of all items under the same Class of Supply (COS) or Federal Supply Class (FSC) is known as specific commodity inventory. This method ensures that every item within a designated category is accounted for accurately, providing a complete and detailed overview of inventory levels.

Specific commodity inventories are critical in logistics as they facilitate precise tracking and management of particular types of materials or supplies. By focusing on all items that share the same COG or FSC, this method enhances the ability to monitor stock levels, manage procurement processes, and ensure that the right quantities are available for operational needs. This is particularly important in military logistics, where maintaining accountability and readiness is essential.

In contrast, random inventory methods do not systematically cover all items within a category, while cycle inventory focuses on counting a subset of goods on a rotating basis, and comprehensive inventory typically refers to a full inventory of all items, rather than categorizing them by COG or FSC.
