What management listing helps ensure that equipment authorizations remain within prescribed allowances?

The ASC listing is specifically designed to help manage equipment authorizations and ensure that they remain within prescribed allowances. This listing provides a detailed account of authorized equipment, including quantities and types, allowing managers to track and verify that the equipment on hand aligns with what is authorized. By regularly reviewing the ASC listing, material managers can identify discrepancies or excesses that may need correction, ensuring that the organization maintains compliance with equipment authorization regulations.

The other options, while related to material management, do not specifically focus on controlling equipment authorizations in the same targeted way. The DOD often pertains to overarching defense policies and guidance rather than specific equipment management. The R15 and Q10 might relate to reporting and tracking mechanisms but do not provide the same direct audit and authorization control function as the ASC listing.
