Because of the cyber military revolution, warfare is no longer adequately defined as violent campaigns and battles sought among armed fighting forces occurring between periods of peace. War is now a continuous battle between diverse multi-faceted actors waged primarily in the virtual cyber domain, occasionally accompanied by violent clashes in the physical domain. When changes to warfare are this fundamental, it requires a new framework of war to guide strategy, doctrine development, and military operations at all levels of warfare. This study uses case studies and analysis to demonstrate why the current framework of war, based upon a theory of warfare described in Carl Von Clausewitz' classical work On War, leaves a conceptual gap that does not fully address the challenges of warfare in the cyber age. To address this conceptual gap, the study recommends a revised framework of war that uses Colonel John Boyd's philosophy of war and his Observe-Orient-Decide-Act loop as the foundational core elements.
