Mission and Vision

USCYBERCOM's Cyber National Mission Force (CNMF) plans, directs and synchronizes full-spectrum cyberspace operations to deter, disrupt and if necessary, defeat adversary cyber actors to defend the U.S. National mission force teams are aligned to support the CNMF.

The CNMF is one of three USCYBERCOM forces that would react to a cyber attack on the nation. The other two forces are the Cyber Combat Mission Force assigned to the operational control of individual U.S. combatant commanders, and the Cyber Protection Force that helps operate and defend the DODIN.
