What is a key characteristic of Navy memorandums?

A key characteristic of Navy memorandums is their informal means of communication. Unlike formal letters, which adhere to strict protocols and formats, memorandums are designed to convey information quickly and efficiently within the Navy. They allow for a more conversational tone, making it easier to share updates, requests, and other relevant information without the rigidity required in formal correspondence.

While some options touch on aspects of Navy correspondence, they do not accurately reflect the primary function of memorandums. For instance, formal letters have specific formats and use-cases that distinguish them from memorandums. Similarly, the requirement for a serial number pertains to tracking official correspondence, but it is not a defining feature of memorandums specifically. Handwritten documents are typically discouraged in formal communications due to legibility concerns, further underscoring the unique nature of memorandums. Thus, the informality of memorandums makes them a practical tool for streamlined internal communication.
