Which Air Force computer system at the base level is used for updating missile records?

The Tactical Missile Record System is specifically designed to facilitate the tracking and management of missile records at the base level. This system ensures that all pertinent information related to missile inventory, status, and maintenance is accurately reported and maintained. By focusing on missile records, it enables personnel to effectively manage and keep track of missile quantities, servicing requirements, and any other necessary documentation related to missile operations.

The other options serve different functions: the Base Information Transfer System (BITS) is primarily used for information transfer across various base-level systems, the Maintenance Management System (MMS) oversees general maintenance tasks rather than specific missile records, and the Logistics Management System (LMS) handles the broader logistics and supply chain aspects rather than focusing exclusively on missile records. This distinction clarifies why the Tactical Missile Record System is the correct choice for updating missile records specifically.
