Unauthorized communication is information you are _________________ to discuss.

Unauthorized communication refers to any information or topic that individuals are not permitted to discuss due to regulations, security protocols, or confidentiality agreements. Identifying that one is "not allowed" to discuss such information highlights the importance of adhering to rules designed to protect sensitive data and maintain operational security. This restriction is crucial in a military context, where the unauthorized release of information could compromise missions, endanger personnel, or violate laws governing national security.

The other terms suggest different levels of permission or obligation that do not accurately reflect the nature of unauthorized communication. "Allowed" implies permission to discuss, "encouraged" implies a recommendation to share information, and "required" indicates an obligation to communicate. However, none of these accurately apply to the context of unauthorized communication, which is fundamentally about restricting dialogue on certain topics.
