  synchronization of these functions with strategic-level partners like the Casualty and Mortuary Affairs
  Operations Division for casualty operations, Military Postal Services Agency for postal, and Human
  Resources Command (HRC) for replacement operations are necessary in order to prolong endurance during
  large-scale combat operations. These habitual support relationships facilitate the CCDR’s ability to extend
  operational reach.
  3-78. During competition, the ASCC G-1 coordinates with corps and divisions to establish theater
  replacement management networks, personnel flow, and postal flow estimates. The ASCC G-1 refines and
  validates the casualty estimate and establishes and manages the personnel portion of reconstitution or
  reorganization efforts. To ensure initial HR capabilities are established prior to the arrival of the main flow
  of forces, HR support elements are included as part of the early entry element of the sustainment brigade
  assigned to the theater opening mission. The TG PAT establishes initial theater personnel accountability and
  theater replacement networks. Its mission is to conduct personnel accountability in the RSOI process, load
  and unload personnel data from the deployed theater accountability system, and conduct limited essential
  personnel services for transient personnel.
  3-79. Additional TG PATs and military mail terminal teams, with corresponding HR companies and
  platoons, could be required if more than one intertheater port of debarkation (POD) is used for RSOI and/or
  mail flows. However, with multiple entry points, it may be necessary for initial personnel accountability to
  be completed by TG PATs or the deploying units themselves. In this case, the arriving personnel data file
  would be passed to the TG PAT at the primary POD.
  3-80. The TG PAT mission does not include conducting any other sustainment-related requirements for life
  support and RSOI (billeting, feeding, equipping, and transportation of transient personnel). These activities
  are conducted by the DSB, sustainment brigade, DSSB, CSSB, or movement control team. For more details,
  see FM 1-0. Planning requirements include the number and placement of HR elements and units (to include
  bands supporting casualty operations) within a theater of operations. HR support responsibilities for early
  entry elements include—
  • Initiating and establishing theater personnel accountability and personnel tracking.
  • Establishing and operating the theater casualty information center and conducting casualty
  operations.
  • Establishing, operating, and maintaining a theater personnel database.
  • Coordinating and synchronizing the establishment of a military mail terminal to support postal
  operations for the theater.
  • Estimating intratheater mail movement (usually by ground) between the military mail terminals and
  Army post offices.
  • Establishing the replacement operations plan.
  3-81. The HROB is part of the early entry element of the sustainment brigade SPO, focusing on ensuring TG
  PAT personnel are included as part of the early entry element for theater opening and the establishment of
  TG PAT support and initial postal support. Early establishment of postal infrastructure during theater opening
  or early entry operations limits the requirements for postal restrictions and allows the flow of mail to
  commence earlier. The HROB receives technical guidance from the TPOC and higher-level HROBs while
  receiving sustainment and execution guidance from the SPO section and the commander.
  Legal Support and Religious Support
  3-82. Legal support assists commands during competition by providing sound legal advice. Judge advocate
  legal services can provide advice on administrative and civil law, contract and fiscal law, military justice,
  national security law, and Soldier and Family legal services. Religious support assists the commander in
  providing for the free exercise of religion and provides religious, moral, and ethical advice and leadership.
  Religious support also advises the commander and staff on religion, ethics, morals, and morale, and their
  impact on all aspects of military operations. For additional information see FM 3-84 and FM 1-05.
  Band Support
  3-83. Army bands support competition by promoting regional stability. Through cultural exchange, bands
  are uniquely capable of influencing human behavior and perceptions without ever speaking a word. Army
