Force Structure: Capabilities and Cost of Army Modular Force Remain Uncertain

The Army considers its modular force transformation the most extensive restructuring it has undertaken since World War II. Restructuring the Army from a division-based force to a modular brigade-based force will require extensive investments in equipment and retraining of personnel. The foundation of the modular force is the creation of standardized modular combat brigades designed to be stand-alone, self-sufficient units that are more rapidly deployable and better able to conduct joint operations than their larger division-based predecessors. GAO was asked to testify on the status of the Army's modularity effort. This testimony addresses (1) the Army's cost estimate for restructuring to a modular force, (2) progress and plans for equipping modular brigade combat teams, (3) progress made and challenges to meeting personnel requirements, and (4) the extent to which the Army has developed an approach for assessing modularity results and the need for further adjusting designs or implementation plans. This testimony is based on previous and ongoing GAO work examining Army modularity plans and cost. GAO's work has been primarily focused on the Army's active forces. GAO has suggested that Congress consider requiring the Secretary of Defense to provide a plan for overseeing spending of funds for modularity.
