  Human Resources (HR) Support
  This chapter provides overviews of HR support, HR support to operations, Army
  command and support relationships, HR support to unified land operations, and HR
  planning and operations. The publication of FM 3-0, Operations, in October 2017
  signaled the readiness focus of the United States (U.S.) Army in how it will deter
  adversaries and fight against a peer threat today, with today’s forces and today’s
  capabilities. Large-scale combat against a peer threat represents the most significant
  readiness requirement; being expeditionary ultimately means deploying on short notice
  and being able to conduct combat operations immediately. Moving from brigade-
  centric operations to fighting corps and divisions as tactical formations in accordance
  with (IAW) FM 3-0 fundamentally changes the calculus behind HR support at echelon.
  Solutions to mitigate risks across doctrine, organization, training, materiel, leadership
  and education, personnel, facilities, and policy areas are being pursued. Implementing
  these solutions is essential in the Army’s success in LSCO because HR support directly
  impacts readiness and sustainability.
  SECTION I – OVERVIEW OF HR SUPPORT
  1-1. Human resources support describes those systems that belong to the manning and personnel services
  support portion of sustaining Soldiers and their systems. Human resources support is an element of personnel
  services aligned under the sustainment warfighting function. The sustainment warfighting function is the
  related tasks and systems that provide support and services to ensure freedom of action, extend operational
  reach, and prolong endurance (ADP 3-0). Systems consist of personnel, networks, information systems,
  processes and procedures, and facilities and equipment enabling commanders to support operations. The
  sustainment warfighting function consists of four major elements: logistics, finance and comptroller
  operations, personnel services, and health service support, each of which must be synchronized across all
  warfighting functions to ensure the appropriate level of support. Each element is guided by a set of specific
  principles. Personnel services are sustainment functions that man the force, maintain Soldier and Family
  readiness, promote the moral and ethical values of the Nation, and enable the fighting qualities of the Army.
  Personnel services support is the management and execution of personnel-related functions including HR,
  legal, religious, and Army band support. This manual will discuss only HR and band support.
  1-2. Human resources doctrine establishes the foundation for HR support activities of HR organizations
  and staffs throughout the Army. Human resources support encompasses two core competencies: man the
  force and provide HR services. Embedded in these competencies are nine critical functions, including:
  * Personnel readiness management (PRM).
  * Personnel accounting and strength reporting (PASR).
  * HR support to casualty operations.
  * HR support to replacement operations.
  * Personnel information management (PIM).
  * Essential personnel services (EPS).
  * Postal operations.
  * Army band operations.
  * Morale, welfare, and recreation operations.
