This study examines the doctrinal requirement for a unified command service component. The historical and descriptive methods are used in this case study of Pacific Command service components. Although the functional approach predominates, comparative analysis is used as well as a descriptive survey to determine the attitudes of officers that have served in the unified command structure. The thesis evaluates the historical evolution of service components from World War II through the post Vietnam period. The role of a service component in joint doctrine is explored, as is the organization and functions of the US Army Pacific, the US Army CINCPAC Support Group, the US Pacific Air Force, and the US Pacific Fleet. Functional analysis of these headquarters provides the basis for discussion of further change. The study concludes that unified command Army service components have historically performed primarily logistical and administrative function, and are no longer necessary. It recommends that (1) joint doctrine be revised to eliminate service components, (2) military departments be tasked to provide a service headquarters to exercise command over operational forces, and (3) staff support functions of a service component be absorbed by a restructured unified command headquarters.
