Chapter 21

This chapter describes the personnel group (PG), its mission, organization, responsibilities, and employment.


The PG mission is to sustain corps (or TAACOM) personnel readiness and to exercise command and control over assigned personnel units. The PG manages critical personnel systems and synchronizes the corps personnel network.


The PG commander also serves as the corps AG. The two positions encompass different responsibilities and require separate manpower. The PG table of organization and equipment (TOE) provides the manpower to satisfy both requirements.

In the command capacity, the PG commander operates on the same plane as other corps major subordinate unit commanders. In the staff capacity, the AG operates as part of the corps staff and directs the corps personnel management center (CPMC) in performing its personnel management mission for both divisional and nondivisional units.


The corps commander exercises command and control over personnel units through the PG commander. The PG combines AG technical expertise with Army command operational planning and command and control capabilities.

The PG is a flexible organization that can adjust to specific mission requirements. Adjustments take place through changing the number and types of subordinate units. The PG normally commands a headquarters detachment, personnel services battalions, replacement companies, and the corps band.


The corps PMC, described in Chapter 13, is summarized in the following paragraphs.

The personnel operations division, excluding the AG, constitutes the CPMC. The division chief is the corps deputy AG. The CPMC has three branches:

  • The personnel readiness branch operates the corps personnel readiness management, personnel accounting and strength reporting (PASR), and replacement management systems.
  • The staff actions branch operates the corps casualty and postal operations management systems and provides essential personnel service to commanders, soldiers, and civilians.
  • The personnel information management branch operates the corps personnel information and data base management functions of the PASR management systems.


The personnel group organizational structure includes the deputy AG/personnel operations division, deputy commander, S1/adjutant, S2/S3 operations officer, S4/supply officer, and headquarters detachment. Their responsibilities are described in the following paragraphs. The personnel group organizational structure is shown at Figure 21-1.


The deputy AG has the following responsibilities:

  • Supervise the personnel operations division.
  • Provide technical direction to subordinate postal units.
  • Synchronize interrelated personnel processes and information exchanges within the corps/TAACOM.
  • Conduct staff assistance visits to subordinate units.


The deputy commander has the following responsibilities:

  • Assist the group commander in command and control.
  • Supervise the internal group staff.
  • Monitor internal compliance with command priorities and policies.
  • Coordinate support requirements for subordinate units with providing organizations.


The S1/adjutant has the following responsibilities:

  • Supervise internal personnel support.
  • Manage internal morale, discipline, and law and order programs.
  • Command the headquarters detachment.


The S2/S3 has the following responsibilities:

  • Supervise internal security, intelligence, plans, operations, training, and communications.
  • Recommend a location for the headquarters based on tactical and functional considerations for the commander's determination.


The S4 has the following responsibilities:

  • Supervise all internal logistics matters.
  • Advise and assist subordinate units in supply, maintenance, and food service.
  • Serve as the group materiel readiness officer.


The headquarters detachment is responsible for administration, supply, food service, and unit-level maintenance operations for the headquarters.


The personnel group coordinates its activities with the corps support command (COSCOM), corps medical facilities, and division G1s.

The COSCOM provides transportation for personnel replacements and mail, direct support maintenance, and reequipping support to replacement companies for return-to-duty soldiers.

The corps medical facilities provide casualty and RTD information on soldiers, civilians, assigned/attached joint and combined personnel, and/or contractor personnel. This information flows through automated systems interface (SIDPERS/TAMMIS) and casualty liaison teams.

The division Gls report on direct support personnel services.


The CPMC normally operates as an element of the corps rear command post (CP). A small cell from the CPMC normally operates with the G1 in the corps main CP.

The personnel group CP normally locates where the commander can best supervise the CPMC, the field operating division, and the PG staff. Ideally, the PG CP and the CPMC collocate.

The corps PG may function as a provisional theater PERSCOM should the corps deploy independently or until the theater PERSCOM can deploy. This role requires additional personnel, communications, and other resources.


The supported unit (corps or TAACOM) must integrate the PG into its mobile subscriber network to provide data transmission capability on a real-time basis. A local or wide area network must link the PG with the supported unit (corps or TAACOM) personnel management centers for information transfer between data bases. If the corps PG acts as the theater PERSCOM, it must have the same level of communications support to provide real-time information flow to the sustaining base and/or USTA PERSCOM.


The PG has limited internal support capability. It can provide food service support for the HQs and collocated units not having organic food service capability. It depends on outside sources for supplemental transportation, DS maintenance, health services, and religious, finance, and legal support.

The PG normally draws defense support from a defense support cluster. It participates in cluster defense under the senior commander's direction or plans and conducts the cluster defense if the personnel group commander is the senior commander. A description of base defense is in Appendix C.


The PG requires 50 percent of its TOE equipment and supplies to be transported in a single lift using its authorized vehicles to provide services in the corps/division areas.
