The official memorandum is the correct choice because it is specifically designed for communication within and between commands. This type of correspondence provides a formal structure that allows for clear and organized communication on official matters, conveying information, directives, or requests in a standardized format. Memorandums are an important tool in military and organizational environments as they help maintain a uniform approach to documentation and communication, allowing for accountability and historical record keeping.

While personal letters and emails can facilitate communication, they often lack the formal structure and protocol that is characteristic of official memorandums. Minutes from meetings, although valuable for record-keeping and summarizing discussions, do not function as a primary means of communication between commands in the same way memorandums do. Official memorandums are tailored to ensure clarity and formality, making them the preferred choice for such correspondence within organizational frameworks.
