As cyberspace continues to play an important role in projection of military power, in an environment where the mission of tomorrow is ill defined and budgets are becoming constrained, there is an increasing need for a Total Force (AC/RC) concept. The existing and emerging requirements for Army Cyber Mission Forces (CMF) are currently greater than the Army's active component has personnel available or trained to support USCYBERCOM and ARCYBER requirements. The Army's RC is uniquely postured to fill current, midterm and longer-term cyber gap requirements, but it requires planning and investment now in training, development, and integrations of the RC CMF. Although moving cautiously, some of the distinct advantages many Reserve Component (USAR and ARNG) Soldiers have are their ties to the communities, full-time employment in the civilian information technology, and their dispersion across the country. Unlike centrally consolidated Title-10 (AC and USAR) organizations, with Homeland Defense and Defense Support to Civil Authorities requirements with limited authorities under the Posse Comitatus Act, the ARNG units can further assist local and state governmental agencies nationwide to defend critical infrastructure networks. These aspects further make the RC uniquely postured to fill current, midterm and longer-term cyber requirements, but it requires planning and investment now in training, development, and integrations of the RC CMF. This analysis accomplishes this through inspection of policy, current requirements, constructs, mission areas and initiatives for RC forces to determine the benefits or drawbacks to successful generation of a Total Force (AC/RC) CMF.
