As threats and opportunities in the cyber domain increase, the military services are formalizing and bolstering their contribution to the nation's cyber force, known as the U.S. Cyber Command Cyber Mission Force. The Army is working to acquire, train, manage, and develop cyber capabilities, and, as a part of a Total Force approach, the Army is considering using both active component (AC) and reserve component (RC) personnel to fill the Cyber Mission Force and other requirements in support of Army units. In fiscal year 2015, the RAND Arroyo Center embarked on a study entitled "Managing and Developing Reserve Component Capabilities in Support of the Army's Cyber Force." As part of this study, we were asked to inventory the cyber skills resident in the Armys RC and identify possible cyber roles and missions for the RC. We were also tasked to recommend approaches to recruiting, training, and assigning RC cyber personnel to support Army cyber operations.
