New DOD doctrine officially outlines and defines ‘expeditionary cyberspace operations’

Mark Pomerleau

For the first time, the Department of Defense has begun to recognize and even define cyber operations conducted in physical or tactical spaces in formal doctrine.

A revised version of Joint Publication 3-12 Cyberspace Operations — published in December 2022 and while unclassified, is only available to those with DoD common access cards, according to a Joint Staff spokesperson — officially provides a definition for “expeditionary cyberspace operations,” which are “[c]yberspace operations that require the deployment of cyberspace forces within the physical domains.”

DefenseScoop has seen a copy of the updated publication.

The last version was published in 2018 and was publicly available. The Joint Staff spokesman noted that five years has been the norm for updates.

The definition, recognition and discussion of such operations are indicative of not only the maturity of cyberspace and associated operations, but the need for more tactical capabilities to get at targets that the current cyber force might not be able to access.

U.S. Cyber Command owns the offensive cyber capabilities within DOD, and the services conduct offensive cyber ops through Cybercom and the cyber mission forces that each service provides to the command. Authorities to launch cyber effects have traditionally been held at the highest levels of government. In recent years, those authorities have been streamlined and delegated. However, most cyber operations are still conducted from remote locations by the cyber mission force (CMF) and primarily focused on IP-based networks.
