As the Department of Defense executes its mission in its newest warfare domain, cyberspace, some have questioned its choices with regard to command and control of its cyber forces. This book examines historical cases of new warfare domains and how the Department of Defense structured the command and control elements of its forces dedicated to the air and space domains. It explores the current cyber command and control construct, and looks at two others that would likely be employed if a change in command and control were to occur. Those examined include a new functional combatant command focused on cyber, similar to U.S. Special Operations Command, and a stand-alone U.S. Cyber Force. This book considers the benefits and drawbacks of each, and seeks to serve as an informative tool should policymakers determine a new command and control model is necessary for cyber forces.
