Which factor should NOT influence the structure of a naval letter?

The overall length of a naval letter should not be a factor in determining its structure. The primary purpose of a naval letter is to communicate effectively, ensuring that the content is clear and understandable. Recipients of naval correspondence often hold various ranks and may have different levels of familiarity with the subject matter. Therefore, the rank of the recipient, the clarity of the content, and the understanding of the audience play crucial roles in shaping how the letter is structured to ensure the message is conveyed appropriately and effectively.

While brevity can be important in communication, the structure of the letter should prioritize clarity and the recipient's needs over a strict adherence to a specific length. Proper structuring should focus more on organizing the information in a way that is accessible and useful to the recipient rather than merely trying to keep the letter short.
