US Army National Guard: Rising to Meet the Challenges of Serving in the Operational Force and Operational Reserve [open pdf - 345KB]
From the thesis abstract: "In 2008, Secretary of Defense Robert Gates issued policy guidance to the Department of Defense to treat the Reserve Components as part of the operational forces. Four years later, the Department of the Army issued Directive 2012-08 to revise policy for integration of the Active and Reserve Components as part of the Army total force. As part of the total force, the Army National Guard contributes to the full range of missions as within the Army's force generation plans. In this role, Army National Guard Soldiers must offer strategic depth as an operational reserve and retain the ability to sustain contributions to the operational force as required. [...] This monograph will examine these four areas to summarize some associated challenges and support recommendations that enable the Army National Guard's current role within the Army's operational force while concurrently serving as a cornerstone of an operational reserve comprised of units identified across the Total Force based on tiered levels of the readiness."
