Which afloat supply division is responsible for postal services?

The correct answer is A, as the S-2 division is specifically tasked with managing postal services aboard a naval vessel. This division handles all matters related to mail delivery, postal logistics, and the management of correspondence for the crew.

The S-2 division is crucial in ensuring that mail is processed, distributed, and accounted for effectively, thus maintaining morale among personnel during deployment. This includes receiving incoming mail, sorting it appropriately, and ensuring timely dispatch of outgoing mail.

In contrast, the responsibilities of other divisions do not encompass postal services. For example, S-1 generally focuses on personnel and administrative matters, S-3 is concerned with operations and readiness, while S-4 typically manages logistics and supply chain functions. Each division plays a unique role in the overall supply chain and operational readiness of the vessel, but only S-2 is designated specifically to handle postal services.
