Lt General (R) Th. Stroup (AUSA) briefly summarizes the US Army Transformation: "Transform the Army into a strategically responsive force dominant across the full spectrum of operations", according to General E. Shinseki, who sets seven broad goals to make the Army more responsive, deployable, agile, versatile, lethal, survivable and sustainable. Army Transformation is a total overhaul of training, doctrine, equipment and institutional thinking. The three key elements are: the legacy force, the heavy force comprising the Army mechanized infantry and armed divisions; the interim force, able to deploy more quickly than the heavy forces and with more combat punch, ground mobility, and soldier protection than light or airborne forces; the objective force representing the aim of what can be done to equip, organize and train unit to assimilate the best aspects of the heavy, light and interim forces. The future combat system (FCS) will be the primary weapon/troop-carrying platform for the objective force, able to direct or indirect fire, infantry carrier, and sensor, and fit on a C-130-sized transport aircraft.
