Chapter 16

This chapter describes the replacement battalion and company and their missions, functions, organization, and employment.


The theater replacement battalion manages the process of moving replacements within the theater of operations. The replacement company is the basic replacement delivery unit on the battlefield. Each company can control up to 400 replacements per day.

Replacement personnel categories are:

  • Soldiers and civilians arriving in theater.
  • Soldiers and civilians moving from one unit to another within the theater.
  • Soldiers and civilians returning to duty from medical or confinement facilities or on straggler status.
  • Soldiers and civilians in transit to or from rest and recuperation areas outside the theater.
  • Soldiers and civilians in transit in- and out-of-theater (for example, emergency leave).


The replacement battalion commands and controls replacement companies. The replacement company commands, controls, and processes replacements in a GS or DS role. Companies in a GS role process replacements at the theater level.


The replacement battalion is responsible for from two to six assigned replacement companies. Figure 16-1 shows the replacement battalion organizational structure.

The replacement battalion has responsibility for the following critical tasks:

  • Synchronize company operations.
  • Provide replacement allocation decisions to their replacement companies based on fill plans from the theater PERSCOM.
  • Coordinate transportation and life support requirements beyond the capability of a replacement company operating in a DS role.
  • Provide internal personnel support.

The replacement company's organization and responsibilities are outlined in the following paragraphs. Figure 16-2 shows the replacement company organizational structure.

Company headquarters is responsible for the following functions:

  • Exercise command and control.
  • Provide internal administration support.
  • Provide food service and billeting for up to 400 replacements.
  • Provide internal logistical support.

The company operations section/staff is responsible for the following:

  • Coordinate operational orders, plans, control, and guidance necessary for mission execution.
  • Coordinate for battlefield orientation.
  • Provide soldier and civilian accountability, make assignments against distribution plans from theater PERSCOM or corps readiness managers, issue orders, and process replacements.
  • Coordinate for replacement transportation (DS replacement company).
  • Coordinate intelligence and security.

The company supply section is responsible for the following:

  • Coordinate for replacement personnel supplies.
  • Reequip personnel returning to duty.

Replacement platoons are responsible for receiving, controlling, accounting for, assigning, and moving replacements. Each platoon can control up to 100 replacements per day.


Replacement companies usually operate as part of a replacement battalion performing the GS mission at theater level or as part of a personnel group performing a direct support mission in a corps or TAACOM. Replacement companies operating in a DS role usually collocate with a personnel services battalion (PSB) to provide ready access to the data base.

At theater level, a personnel replacement battalion exercises command and control over the replacement companies. The companies are interchangeable in their GS and DS roles. The company's primary role at theater level is to receive, process, support, and coordinate transportation for replacements to DS replacement companies or division replacement sections. It also provides direct support (delivery) to units in close proximity.

At corps and TAACOM level, replacement companies operate almost exclusively in a direct support role. They receive replacements from theater-level replacement platoons and coordinate delivery directly to gaining organizations. They also provide this support to separate brigades, which have no organic replacement processing capabilities.

Division replacement sections can receive replacements directly from theater-level replacement units. However, conditions may exist which make it impractical to move replacements directly from theater level to division.

Additionally, the replacement flow may exceed division processing capability. Under such circumstances, the corps replacement company must receive, process, and deliver replacements or augment the division replacement section. The corps replacement company may also require additional resources at this time which are normally drawn from replacement stream personnel or the PSB.

Personnel replacement battalions with two to three replacement companies are also designated to support CRCs. The personnel replacement battalion will receive, process, and equip replacement soldiers and civilians at installations. Replacement companies of a CRC personnel replacement battalion do not have replacement supply sections and require supply support from the installation. The CRC mission and organization is described in Chapter 17. A replacement unit in a forward-deployed theater is also responsible for redeploying individuals to another theater similar to the functions of a CRC in CONUS.


The replacement battalion and replacement company organizational designs allow them to operate a long distance from their parent units, the PERSCOM/personnel group and replacement battalion, respectively. However, they have little internal support capability. They depend on outside sources for transportation, communication, DS maintenance, health services, and religious, finance, and legal support. The replacement battalion may also require outside food service support. The replacement company has its own food service section and will coordinate for additional food service support when feeding over 400 personnel.

The replacement company location determines the support sources. Replacement companies/platoons supporting and located within divisions draw their support from the division. The replacement battalion/replacement companies located within the corps or TAACOM area of operations draw their support from those organizations.

Replacement battalions and companies normally draw defense support from a defense support cluster. They participate in cluster defense under the senior commander's direction.


The replacement battalion requires 30 percent of its TOE equipment and supplies to be transported in a single lift using its authorized vehicles to provide services in theater areas. The replacement companies require 50 percent of their TOE equipment and supplies to be transported in a single lift to provide services in the corps and division areas. They must have adequate organic transportation for all personnel and equipment (TOE, CTA, and automation).


The replacement battalion and companies must be integrated into a mobile subscriber network to provide data transmission capability on a real-time basis. The wide area network/mobile subscriber network will also link the replacement battalion and companies with the supported unit (corps, TAACOM, or division) personnel management center (PMC) for information transfer between data bases.
