A cyber force is a military branch devoted to cyberwarfare, cybersecurity, and counter-cyberwarfare. Its responsibilities could also include operations to combat cyberterrorism and to establish cyber power projection. A cyber force can be part of a military branch or a combined command. Presently, it has no official definition although the United States Department of Defense Dictionary of Military and Associated terms provided relevant concepts that indicate cyber force could be constituted by personnel who conduct cyberspace operations in cyberspace and the activities include computer network operations, and the routine operation and defense of cyberspace.
