Reinforcing Operations Security and the Importance of Preventing Unauthorized Disclosures [open pdf - 1016KB]
From the Document: "Proper Operations Security (OPSEC) is critical to protecting our forces, ensuring our mission success, and implementing the National Defense Strategy. History is full of examples of poor OPSEC leading to the unnecessary loss of life and mission failure, and it can mean the difference between our winning and losing as we face great power competitors that will not hesitate to exploit and weaponize information. The Department of Defense (DoD) remains committed to transparency to promote accountability and public trust. However, it is important to emphasize that unclassified information is not publicly releasable until it is approved for release by an appropriate authorizing official. Unfortunately, poor OPSEC practices within DoD in the past have resulted in the unauthorized disclosure or 'leaks' of controlled unclassified information (CUI), including information to be safeguarded under the CUI category for OPSEC, as well as classified national security information (together referred to here as 'non-public information'). Unauthorized disclosures jeopardize our DoD personnel, operations, strategies, and policies to the benefit of our adversaries. Unauthorized disclosures also distract from mission priorities by redirecting the attention and resources of military commanders. [...] Unauthorized disclosures, regardless of purpose or intent, can result in adverse personnel action, including unsatisfactory performance evaluations, records of formal counseling, the loss of security clearances or termination of employment, or even criminal prosecutions."
