When is it necessary to use formal language in correspondence?

Using formal language in correspondence is especially important when addressing a superior officer. This practice demonstrates respect and acknowledges the hierarchy within the Marine Corps. Formal language helps to convey professionalism and seriousness in communication, which is crucial in a military environment where clear and respectful interactions are expected.

In correspondence with superior officers, the use of formal language ensures that the content is received with the appropriate level of respect and authority. It can also reflect the writer's understanding of military protocol and structure, which reinforces the chain of command and fosters effective communication.

In contrast, other forms of correspondence, such as those directed at subordinates or coworkers, may allow for a more informal tone, depending on the context and the relationship between the individuals involved. However, when it comes to superior officers, maintaining a formal tone is not only a best practice but a reflection of professional military standards.
