MCO 3070.3 addresses PPED risks, force protection, OPSEC, signature management, counterintelligence, education, enforcement, and technical oversight. It requires updated training, commander enforcement, and local orders tailored to operational needs within established parameters.
PPED use can reduce situational awareness, compromise privacy, and threaten operations security (OPSEC) per reference (a). (paragraph 1)
Per reference (c), non-official personal messaging accounts, including, but not limited to, e-mail, social media, or other messaging applications, are not permitted to be used for official business based on personal convenience or preference. (paragraph 1)
Commanders are essential to the enforcement PPED regulations. While commanders must address all reported PPED violations, they remain authorized to determine the best manner to deal with violations. (paragraph 2)
Force protection is the warfighting function that enhances the survivability of the force by allowing us to conceal our capabilities and intentions. It relies upon OPSEC, signature management (SIGMAN), operation risk management (ORM), and counterintelligence (CI). (paragraph 2)
While this Order encourages commanders to use available tools to detect emissions in support of PPED use restrictions, it does not authorize collection of information, such as metadata, content, or publicly available information in support of PPED technical oversight. (paragraph 2)
