Marking Documents


Distribution Limitations

The information DTIC collects, stores and distributes carries security classifications up to the Secret level. The information should be marked by the controlling organization to show how it may be distributed. DTIC's registration process and access to DTIC data differs for users based on the distribution limitations set by the controlling organizations.

Much of the information in DTIC's databases can be released to the public. This information is referred to as UNCLASSIFIED, UNLIMITED (U2) PUBLIC RELEASE.

The databases also contain information that, although not classified, is sensitive. Such documents are considered UNCLASSIFIED, but their distribution is controlled. This information is referred to as Controlled Technical Information (CTI), which is a category of Controlled Unclassified Information (CUI).

Many of the limits on distribution have to do with whether or not the user is:

  • an authorized employee of the Department of Defense.
  • an authorized employee of another U.S. Government agency.
  • an authorized contractor for either the Department of Defense or another U.S. Government organization.


Distribution Statements

Beyond the provisions of security classifications, all documents must carry distribution statements that describe conditions for their distribution, release, or disclosure.

DoD Instruction (DoDI) 5230.24, Distribution Statements on Technical Documents, states that all documents sent to DTIC must be assigned a distribution statement by the contributor. It was revised effective 10 January 2023 and aligns marking procedures for controlled technical information (CTI) in accordance with DoD Instruction (DoDI) 5200.48, "Controlled Unclassified Information (CUI).
