Which classification level is indicated by //NU?

The classification level indicated by "//NU" is NATO UNCLASSIFIED. This designation signifies that the information is not subject to specific restrictions concerning handling and dissemination, indicating that it is open for public access. NATO UNCLASSIFIED materials can be shared without special clearance, and they do not contain sensitive information that could compromise security or operational integrity if disclosed.

Understanding this classification is essential because it helps identify what information can be released to the public and what remains restricted. It is also important to be familiar with the other NATO classification categories, which include NATO SECRET, NATO CONFIDENTIAL, and NATO RESTRICTED. Each of these levels imposes specific handling requirements and controls to protect sensitive information and prevent unauthorized access.
