  * Establish HR support for replacement operations.
  * Establish and operate the theater CIC.
  * Establish initial theater postal operations.
  7-32. During operations to prevent, early TPFDD divisions and brigades have pushed forward out of the
  strategic support area into the joint security area. Human resources elements continue assisting commanders
  with setting the theater, tailoring and projecting HR support to the force. Brigade S-1s identify shortages and
  requirements for HRC to bring their units up to authorization in preparation for LSCO (individual
  replacements identified for unit manning may be identified as late deployers).
  7-33. In the operational support area, the ASCC G-1/AG continues planning, establishing policy, setting
  priorities, and managing PASR for the theater and identifies internal and external HR support requirements.
  The ASCC G-1/AG continues coordinating with the combatant commander to ensure Army PASR policies
  synchronize with joint policies and field army requirements. The ASCC G-1/AG continues planning,
  coordinating, and managing casualty operations for the theater and identifies any additional locations
  requiring placement of casualty liaison elements. These locations are in addition to the normal General
  Officer-level HQ, G-1/AGs, Role 3 MTFs, and mortuary affairs collection points. The ASCC G-1/AG also
  continues planning, coordinating, establishing, and managing postal operations for the theater, and identifies
  and coordinates with the TSC and TPOC to ensure adequate postal operations resources are available
  throughout the theater AO.
  7-34. In the division AO/division consolidation area, the division G-1 conducts key HR tasks such as PASR,
  HR support to casualty operations, PRM, EPS, and PIM. They also maintain personnel asset visibility
  throughout all operations and collect data gathered by subordinate S-1s to adjust HR support to subordinate
  organizations as required.
  7-35. In the brigade AO/brigade consolidation area, generally, there are no HR companies or any other SRC
  12 element supporting brigades. However, with proper coordination between brigade S-1s and division G-1,
  additional support may be requested from the supported division. In support of RSOI, S-1s continue to focus
  on manning the force and HR support to casualty operations (casualty reporting). They also perform
  mailroom operations and continue providing EPS for their organizations. Brigade and subordinate S-1s
  receive and track all attached and assigned Soldiers, DOD and DA Civilians, and CAAF operating in the
  unit’s AO. Maintaining visibility through operations and tactical enablers assists S-1s in gathering data
  necessary to perform their missions. Tactical communications can provide information on unit moves,
  casualties, task organization changes, and other information affecting HR operations. Maintaining this
  visibility provides redundant and new information that S-1s can input into the HR system of record.
  HR PLANNING CONSIDERATIONS BY ECHELON FOR
  OPERATIONS TO PREVENT
  7-36. The following paragraphs, listed from strategic to tactical level, include HR planning considerations
  by echelon for operations to prevent to support LSCO.
  HQDA G-1
  7-37. Human resources planning considerations for the HQDA G-1 during operations to prevent may
  include, but are not limited to––
  * HR support to replacement operations:
   Ensure readiness of personnel to serve the needs of the Army across the range of military
  operations.
   Coordinate with HQDA DCS G-3/5/7 to determine manning levels and turbulence thresholds
  for units within the operational force, operational depth, and generating force to include the
  institutional Army.
   Continue providing integration and synchronization to identify/provide filler/personnel
  replacement requirements for each OPLAN (ASCC responsible).
