  OVERVIEW OF HR SUPPORT TO LARGE-SCALE COMBAT
  OPERATIONS (DEFENSIVE/OFFENSIVE)
  7-49. Under large-scale combat operations, the operational environment remains a complex extended
  battlefield against a peer adversary; deterrence efforts have failed, force projection operations are underway,
  decisive action operations have commenced. Characteristics of sustaining LSCO include volume, lethality,
  precision, and tempo. Peer threats with modern weapons employed en masse will have the potential to
  overwhelm maintenance, medical, replacement personnel, and mortuary affairs capabilities. Peer threats can
  influence and direct irregular forces, criminal elements and hostile populations, and can impose disruptive
  effects in cyberspace challenging Army sustainment during force projection. The threat will employ their
  resources across multiple domains to attack U.S. vulnerabilities including sustainment facilities, networks,
  and formations. They create lethal and non-lethal effects throughout the operational environment; seek to
  inflict significant damage across multiple domains in a short period and see to delay friendly forces long
  enough to achieve their goals.
  7-50. Based on the peer threat capability across multiple domains, formations conducting decisive action
  within the JOA will need to establish smaller temporary bases that are more dispersed and mobile than
  conventional bases. Considering the credible threat capability and dispersed array of friendly forces, LSCO
  will require a higher volume of personnel, materiel, and equipment significantly greater than other types of
  operations. Large-scale combat operations will necessitate high operational tempo and is more lethal than
  other types of operations resulting in more casualties (mass casualties), replacement personnel, and
  equipment on a larger scale.
  7-51. During defensive and offensive operations, HR planners should expect large numbers of casualties in
  a short period or over extended depths of the battlefield and must be prepared to process mass casualties and
  replacement personnel on a large-scale to include reconstitution to maintain PASR and to build and sustain
  combat power. Personnel replacements must be forecasted and any lack of replacement capacity briefed to
  maneuver commanders as a risk to the mission. A high intensity operational tempo, coupled with potentially
  degraded systems and communications, will negatively impact personnel status and casualty reporting.
  Human resources planners can also utilize push package planning to forward position replacements and assist
  with replacement flow. If communications are degraded, sustainers automatically dispatch these push
  packages to supported units.
  7-52. During LSCO, HR elements focus on accurate and timely personnel accounting, information, and
  readiness management to rapidly generate and sustain combat power. Key HR entities to support defensive
  and offensive operations during LSCO will be challenged by degraded communication (reporting latency and
  accuracy issues) and highly-contested, lethal and non-lethal environments. To support RSOI, support to
  replacement and casualty operations are two of the key tasks that must be prioritized and synchronized to
  allow commanders the freedom of action to maneuver and provide extended operational reach. Key HR
  activities identified for LSCO (defensive/offensive) include––
  * Personnel asset visibility/strength reporting.
  * HR support to replacement operations (RSOI).
  * HR support to casualty operations (casualty reporting).
  * HR support to reconstitution operations.
  7-53. During LSCO, the ASCC G-1/AG continues planning and prioritizing HR support to assure a unity of
  purpose and effort maximizing the readiness and operations capabilities of forces within theater. The ASCC
  G-1/AG continues to monitor strength and determine replacement priorities with the G-3/commander,
  monitor replacement operations, and monitor any reassignments to meet operational requirements.
  7-54. The TPOC continues to integrate and execute planning, PASR, and postal operations (with respective
  restrictions, if any) throughout the theater as defined by the ASCC G-1/AG. The TPOC provides technical
  guidance and oversight to theater HR elements and coordinates with the TSC for replacement flow.
  7-55. Human resources operations branches, collocated with ESC DMCs and sustainment brigade SPOs,
  continue planning, coordinating, integrating, and synchronizing and allocating HR support to casualty
  operations, postal operations missions, and HR assets within the DSB and ESC AO. They also continue to
  serve as the main integrator between the TPOC and assigned and attached HR units (HR company, TG PAT,
