  sustainment command (ESC) with staff augmentation from other Service components is designed to fulfill
  that mission.
  ARMY TITLE 10 SUSTAINMENT REQUIREMENTS
  1-77. Title 10, USC and Department of Defense Directive (DODD) 5100.1 describe the organization, roles,
  and responsibilities for the elements of the DOD to include the statutory requirements for each military
  department. In accordance with Title 10, each Service retains responsibility for the sustainment support of
  forces it allocates to a joint force. The Secretary of the Army exercises this responsibility through the United
  States Army Chief of Staff and the ASCC assigned to each CCMD. For conventional forces not assigned to
  CCMDs, the Secretary of the Army established the commanding general of United States Army Forces
  Command (FORSCOM) as the Army's Service force provider. The ASCC is responsible for the preparation
  and administrative support of Army forces assigned or attached to the CCMD. Theater ASCCs also support
  Army special operations forces (ARSOF). United States Army Special Operations Command (USASOC)
  provides ARSOF to CCMDs to perform theater special operations missions.
  1-78. Support provided to other Services while executing assigned EA or lead Service responsibilities is
  commonly referred to as Army support to other Services. In both instances, the ASCC supports sustainment
  requirements through its designated TSC, ESC, and theater medical command (TMC).
  1-79. The Army has twelve Title 10 responsibilities; nine (bold lettering) are sustainment related:
  • Recruiting.
  • Organizing.
  • Supplying.
  • Equipping (including research and development).
  • Training.
  • Servicing.
  • Mobilizing.
  • Demobilizing.
  • Administering (including the morale and welfare of personnel).
  • Maintaining.
  • Construction, outfitting, and repair of military equipment.
  • Construction, maintenance, repairs of building and structures, utilities, acquisition of real
  property and interests in real property necessary to carry out the responsibilities.
  1-80. The purposeful combination of complementary Service capabilities to create joint interdependent
  forces is often the most effective and efficient means by which to sustain a joint force. Therefore, additional
  authorities to Title 10 have been developed to provide for interservice and interagency mutual support.
  ARMY EXECUTIVE AGENT RESPONSIBILITIES
  1-81. Executive agent is a term used to indicate a delegation of authority by the Secretary of Defense or
  Deputy Secretary of Defense to a subordinate to act on behalf of the Secretary of Defense (JP 1, Volume 2).
  EA refers to Secretary of Defense directives and instructions to the head of a DOD component (such as Chief
  of a Service, CCDR, or director of a combat support agency) to provide specific categories of support to other
  agencies or Service components. The Secretary of Defense designates and funds the Army as the EA for
  numerous DOD common support requirements. Examples of the Army’s sustainment-related responsibilities
  and support to other services as provided in DOD directives and joint publications are shown in table 1-2.
  These DOD-level EA requirements relate to lead Service responsibilities. EA reduces redundancy of common
  support requirements across the DOD. However, in many cases, lead Service requirements will be closely
  related to the DOD EA requirements. The CCDR has the authority to assign lead Service responsibilities for
  support to a Service that are not EA related.
