In military security, SBU documents are unclassified.

• A. True
• B. False
• C. Not defined
• D. Depends

Answer: (A)

SBU stands for Sensitive But Unclassified, a label used for information that isn’t assigned a formal classification level like Secret or Top Secret but still needs protection. In military security practice, such documents are considered unclassified in terms of classification, yet they require controlled handling: restricted distribution, proper marking, secure storage, and secure transmission. So the statement is correct because SBU denotes information that is not classified, but must be safeguarded due to its sensitivity.

This distinction matters because not all unclassified information can be freely shared; SBU signals that even though there’s no formal classification, disclosure could still cause harm and thus should be treated with care. The other options don’t fit because the designation exists precisely to denote unclassified but sensitive material, not something undefined or dependent on context, and it’s not inaccurate to say it’s unclassified.
