  Tailoring the force is a complicated and intensely managed Army-wide process, and the theater army plays
  a critical role in it.
  2-63. Most Army conventional operating forces are designated as “Service Retained” forces in the Global
  Force Management Implementation Guidance assignment tables and are primarily based in the continental
  United States. United States Army Forces Command (FORSCOM), the largest of the Army commands,
  commands Active Component conventional forces (Regular Army, mobilized Army National Guard, and
  mobilized Army Reserve), executes training and readiness oversight of Army National Guard forces under
  state command, and it does the same for non-mobilized Army Reserve units.
  2-64. Based upon requirements developed by the theater armies and validated by the combatant commander
  and the joint staff, the Department of the Army and FORSCOM develop force packages for deployment and
  employment into an AOR. This includes forces for contingencies and forces needed to support security
  cooperation activities. A tailored force package is task-organized by FORSCOM to facilitate strategic
  deployment and support the gaining JFC’s operational requirements. FORSCOM is not the sole provider of
  Army forces; other supporting ASCCs may contribute forces as directed by the Secretary of Defense. The
  result is a set of trained and ready Army forces intended either for contingencies or for planned deployments,
  such as a rotation of forward-based forces.
  2-65. The theater army recommends the optimum deployment sequence for Army forces to the GCC’s staff.
  The GCC’s staff may modify this recommendation in coordination with FORSCOM and United States
  Transportation Command (USTRANSCOM) based upon factors such as available lift, location, and readiness
  of deploying forces, and surface transportation requirements. The theater army adjusts support provided by
  theater assets to match the requirements of the joint and Army forces on the ground. Figure 2-6 shows an
  example of force tailoring.
