The Department of Defense (DOD) is endeavoring to define war fighting in the global cyberspace domain.1 Creation of US Cyber Command (USCYBERCOM), a subunified functional combatant command (FCC) under US Strategic Command (USSTRATCOM), is a huge step in integrating and coordinating the defense, protection, and operation of DOD networks; however, this step does not mean that USCYBERCOM will perform or manage all cyberspace functions. In fact the vast majority of cyberspace functions conducted by the services and combatant commands (COCOM), although vital for maintaining access to the domain in support of their operations, are not of an active war-fighting nature. We apply the concepts of war fighting, offense, and active defense to the domain of cyberspace and propose several recommendations to aid USCYBERCOM as it works with the services and geographic combatant commands (GCC) to fight in cyberspace. That global, regional, and service commanders will have to share command and control (C2) of cyberspace war-fighting capabilities and forces raises several interesting questions about how USCYBERCOM can most effectively work with the GCCs. Specifically, what is the ideal force presentation method, and which C2 model should the DOD use for war-fighting capabilities in cyberspace? Are there lessons learned from similar global-to-regional support challenges that we might apply to cyberspace C2? We offer US Special Operations Command (USSOCOM) as a model for cyberspace force presentation and C2; however, this model is a long-term goal that is not immediately achievable. In the interim, USCYBERCOM can adapt lessons learned from space and air-mobility force presentation and C2 to develop a building-block approach to evolve cyber force presentation and C2 from its current nascent state to a more mature USSOCOM- like state.
