Unit commanders must appoint unit cargo increment monitors in writing to which agency?

Unit commanders are required to appoint unit cargo increment monitors in writing to the Host Log Plans Function. This appointment is crucial because the Host Log Plans Function is typically responsible for overseeing logistics planning and operations within the unit. By designating a cargo increment monitor, commanders ensure that there is a specific individual tasked with managing and tracking cargo increment requirements, which is vital for maintaining efficient supply chain operations and ensuring that all logistical needs are met.

This role includes responsibilities such as coordinating with other logistical units and ensuring compliance with established guidelines regarding cargo increments. The involvement of the Host Log Plans Function helps streamline logistics processes and fosters better communication across units, facilitating more effective overall operations.

The other options refer to different roles or commands within the Air Force which do not specifically align with the responsibilities of overseeing cargo increment monitors directly, making them less relevant to this specific appointment requirement.
