text: Human Resources (HR) Support
  HR support requirements for subordinate or supported organizations within the theater and forwards the HR
  support requirements to the appropriate HROB. Once requests are received, the HROB evaluates the request
  against available resources and DSB unit priorities. If the sustainment brigade can provide the support
  requested, then it is coordinated with the HR company. If the request cannot be supported, it is forwarded to
  the ESC. The HROB recommends HR priorities of support to the sustainment commander. Human resources
  support requirements that cannot be resolved by the sustainment brigade or ESC/TSC are forwarded to the
  ASCC G-1/AG for prioritization and reconciliation. The ASCC G-1/AG, in coordination with the TSC (with
  the support of the TPOC), reconciles prioritization issues to ensure required HR support structure is available
  for the theater, within the ability of the Army to resource.
  SECTION IV – OVERVIEW OF HR SUPPORT TO UNIFIED LAND OPERATIONS
  1-61. Unified land operations are the simultaneous execution of offense, defense, stability, and defense
  support of civil authorities across multiple domains to shape operational environments, prevent conflict,
  prevail in large-scale ground combat, and consolidate gains as part of unified action (ADP 3-0). Sustainment
  operations enable all phases of joint operations in each of the Army’s four strategic roles: shape the
  operational environment, prevent conflict, prevail in large-scale combat, and consolidate gains. This is
  skillfully accomplished by integrating and synchronizing resources from strategic through tactical levels.
  1-62. Army operations to shape link activities intended to promote regional stability and establish conditions
  for a positive conclusion in the event of a military confrontation. The purpose is to set the conditions for
  successful execution of strategic plans. Global and theater shaping activities occur continuously. Army
  operations to prevent are an extension of operations to shape and include all activities intended to deter an
  adversary’s undesired actions, which contradict U.S. interest. Operations to prevent include actions to
  safeguard friendly forces and indicate the intent to execute subsequent phases of a planned operation. During
  LSCO, Army forces focus specifically is on defeating and destroying enemy ground forces a part of the joint
  team. Army operations to consolidate gains primary focus is to establish security in high threat areas and
  include activities to make enduring any temporary operational success and to establish conditions for a
  sustainable environment to the control of legitimate authorities. See FM 3-0 for more information on the
  Army strategic roles.
  1-63. Army sustainment provides the support required to keep the Army and its unified action partners
  engaged in operations across the operational environment. It is a critically important requirement to ensure
  adequate HR support is in place for PASR, HR support to replacement operations, and HR support to casualty
  operations to enable the maneuver commander the ability to maintain operational tempo. If tempo is not
  maintained, the possibility of the defeat of friendly forces on the ground is increased. It is imperative for HR
  professionals to synchronize with operational planners in the planning, preparation, execution, and
  assessment of the operation because HR tasks and functions are conducted throughout all phases of joint
  operations in each of the Army’s four strategic roles.
  Note. Refer to chapter 7 of this publication for a detailed overview of HR support and planning
  considerations for each Army strategic role, by echelon, for conducting PASR, HR support to
  replacement and casualty operations, postal operations, and other HR considerations incorporated
  during LSCO.
  OPERATIONAL REACH, FREEDOM OF ACTION, PROLONGED
  ENDURANCE
  1-64. The sustainment warfighting function is essential for conducting operations and generating combat
  power as the Army performs its strategic roles. Human resources support to unified land operations is a
  mission essential capability that creates strategic and operational reach, enables freedom of action, and
  provides the joint force prolonged endurance necessary to shape the operational environment, prevent
  conflict, prevail in large-scale combat, and consolidate gains.
