Which publication should be referred to for finding an AE item's controlled item inventory code (CIIC)?

The correct choice is the Yellow Book, which is specifically designated for providing detailed information about various ammunition and explosives, including their controlled item inventory codes (CIIC). The CIIC is a crucial piece of data as it classifies the security and handling requirements associated with a specific type of ammunition or explosive material. By referring to the Yellow Book, personnel can ensure they are maintaining compliance with all regulations concerning the inventory and security of controlled items.

The other publications serve different purposes. For instance, the Red Book typically contains information on ammunition supply and is focused more on logistics rather than specific codes. The Blue Book is often used for technical specifications and guidance regarding weapons systems and their corresponding ammunition, while the Green Book generally pertains to safety and handling procedures, not inventory coding. Each publication has its own distinct role within the broader framework of ammunition handling and safety, making it essential to consult the appropriate one for the specific information being sought.
