What is the primary purpose of letters in Army writing?

The primary purpose of letters in Army writing is to inform. In a military context, effective communication is crucial for operational success, clarity of orders, and coordination among units. Letters are often used to convey important information, instructions, or updates regarding operations, training, and policy. This focus on informing helps ensure that all personnel understand their roles and responsibilities, as well as the larger mission objectives.

While other purposes like persuading, negotiating, or entertaining may have their place in different types of writing, they are not the central aim of military correspondence. The concise and factual nature of Army writing underscores the importance of clarity and efficiency in communication, making the informative aspect paramount.
