To whom must unit commanders appoint unit Cargo Increment Monitors in writing?

Unit commanders must appoint unit Cargo Increment Monitors in writing to the Host Logistics Plans Function because this role is essential in managing and coordinating the unit's cargo increment activities. The Host Logistics Plans Function typically oversees logistical operations and ensures that the unit complies with the proper procedures for cargo movement. Appointing the Cargo Increment Monitors to this function facilitates effective communication and support between the unit and the logistics planning team, ensuring that cargo is accounted for, tracked, and moved according to established protocols.

The other options, while they may have relevant responsibilities, do not directly fit the role of overseeing and coordinating the specifics related to cargo increment management. For instance, Base Operations Support primarily deals with the administration of base-level support activities, while the Transportation Officer focuses on overall movement and transportation logistics rather than specifically managing cargo increments. The Installation Command Team includes leadership that oversees broader operational aspects but would not be the direct point for such specific appointments. Thus, the Host Logistics Plans Function is the most appropriate and effective oversight body for the Cargo Increment Monitors.
