Does classic OPSEC advise against discussing missions or capabilities in public?

Classic OPSEC, or Operational Security, emphasizes the importance of safeguarding sensitive information regarding missions, capabilities, and other operational details. The core principle of OPSEC is to prevent unauthorized disclosure of information that could be advantageous to adversaries. Discussing missions or capabilities in public can inadvertently provide insights that might help adversaries in planning countermeasures or attacks, thus compromising the overall security and success of operations.

By adhering to the principle that such discussions should be avoided, OPSEC aims to maintain a tight control on information exposure. This commitment to secrecy is crucial, as even seemingly innocuous comments can lead to significant vulnerabilities. Therefore, the assertion that classic OPSEC advises against discussing missions or capabilities in public aligns clearly with the guiding philosophies of operational security.
