Which AT Code is used for NON-COSAL authorized add items based on specific TYCOM authority?

The correct choice reflects that ATC 5 is specifically designated for NON-COSAL authorized add items based on specific TYCOM (Type Commander) authority. This classification is essential within Navy logistics as it allows for the management of items not typically considered part of the Consolidated Operational Stock List (COSAL), thereby ensuring that the fleet has the necessary support and supplies that may be required but are not standard inventory.

In contrast, other AT Codes, such as ATC 3, ATC 4, and ATC 6, serve different purposes within the logistics and supply chain management framework. For example, ATC 3 usually relates to items that are part of a repairable component, while ATC 4 often applies to components that are consumable but may be subject to different procurement processes. ATC 6 pertains to other logistical categories that do not cover the specific needs addressed by NON-COSAL items. Understanding these classifications is critical for effective inventory management and ensuring the readiness of naval operations.
