  THEATER SUSTAINMENT COMMAND
  2-21. The TSC is the Army’s command for the integration and synchronization of sustainment in the AOR.
  The TSC connects strategic enablers to the tactical formations. It is a theater-committed asset to each ASCC
  and focuses on Title 10 support of Army forces for theater security cooperation and the CCDRs daily
  operational requirements. The TSC commands assigned human resources sustainment centers and Financial
  Management Support Centers. The TSC commander also commands and task organizes attached ESCs,
  sustainment brigades, and additional sustainment units. The TSC executes the sustainment concept of
  support for planning and executing sustainment-related support to the AOR for all the Army strategic roles
  (shape OEs, prevent conflict, prevail in large-scale ground combat, and consolidate gains).
  2-22. The TSCs execute sustainment operations through their assigned and attached units. The TSC
  integrates and synchronizes sustainment operations across an AOR from a home station command and control
  center or through a deployed CP. The TSC has four operational responsibilities to forces in theater: theater
  opening, theater distribution, sustainment and theater closing.
  2-23. The task-organized TSC is tailored to provide operational-level sustainment support within an assigned
  AOR. It integrates and synchronizes sustainment operations for an ASCC including all Army forces forward-
  stationed, transiting, or operating within the AOR. The TSC coordinates Title 10, Army support to other
  Services, DOD executive agent (EA), and lead service responsibilities across the entire theater.
  2-24. The TSC organizes forces, establishes command relationships and allocates resources as necessary to
  support mission requirements, and exercises command and control over attached sustainment forces. The
  TSC supports the ASCC sustainment cells with planning and coordinating theater-wide sustainment. The
  execution of sustainment is decentralized, performed by the human resources sustainment centers, Financial
  Management Support Centers, ESCs, sustainment brigades, and other sustainment organizations. The
