Reconstitution is extraordinary action that commanders plan and implement to restore units to a desired level of effectiveness commensurate with mission requirements and available resources. It transcends normal day-to-day force support actions in that it requires a task force to support attrited units and it occurs in a relatively secure regeneration site. The major elements of the reconstitution process are reorganization, assessment, and regeneration.

The CSG role in reconstitution is to --

  • Assist in reorganization of subordinate units.
  • Continue providing support to units undergoing reorganization.
  • Assist in assessment of attrited units.
  • Execute the logistics portion of regeneration.








Reorganization involves shifting organic resources within a degraded unit to increase its effectiveness until more extensive efforts can take place. It maybe either immediate or deliberate. Immediate reorganization is the quick and usually temporary restoring of degraded units to minimum levels of effectiveness. Deliberate reorganization is conducted when more time and resources are available. It usually occurs farther to the rear than immediate reorganization. CSG subordinate units continue to support elements undergoing reorganization to the limit of their organic capability.

Subordinate battalions, their units, and the CSG HHC could require reorganization to increase their effectiveness. Subordinate commanders continually assess unit effectiveness. The commander decides when his unit requires reorganization.


The CSG commander approves the deliberate reorganization of subordinate battalions. Subordinate battalion commanders approve the immediate reorganization of subordinate units. If a viable chain of command exists, internal command of the attrited unit remains with the unit.


Immediate battlefield reorganization normally occurs in position. Commanders take quick and temporary measures to reestablish the chain of command and restore attrited elements to minimum levels of effectiveness. Company commanders reorganize their attrited unit by combining squads, teams, and platoons. Battalion and group commanders quickly shift equipment and personnel between subelements. The CSG support operations officer cross-levels maintenance test equipment, replacement assemblies, or shop sets among DS maintenance units.

All subordinate unit FSOPs designate a succession of command. FSOPs include battle rosters, redistribution criteria, and contingency manning standards. They also outline procedures to reestablish the CP.


More time and resources must exist to conduct deliberate reorganization. With more time, equipment repair may be more intensive. Replacements may also become available. Subordinate battalions cross-level personnel, supplies, and equipment based on group/COSCOM directives and corps priorities. CSGs reorganize subordinate units by shifting subelements within or between CSBs or by combining subordinate attrited units.

The CSG's reorganization plans specify the use of subordinate unit and battalion personnel to restore battalion and CSG staff elements. These plans also outline the use of CSG or COSCOM staff to restore succession of command.


The CSG's S3, S1, and support operations staff help assess the ability of subordinate units to continue their assigned missions.

CSG S1 staff identify personnel in subordinate units who have MOSS in mission essential areas. Group and battalion S1 staff prioritize replacement personnel to under strength subordinate units.

The CSG support operations officer changes the supported customer list to allow subordinate units time in which to reorganize and replenish their basic loads. As a result, supported customers obtain support from another DS supply, field services, or maintenance unit. The CSG support operations officer shifts repair priorities to speed the return of critical, mission essential equipment to the attrited unit.


At the direction of the corps commander, the RTF commander dispatches assessment elements. Personnel and equipment assigned to each assessment element remain METT-T dependent.

Assessment elements travel to a link-up point to marshal unit resources and begin assessment. Assessment of areas listed on Table D-1 helps them to determine regeneration requirements. They arrange for de graded units to move to the regeneration site. If required, the RTF commander adds MCT personnel to the assessment element to help coordinate the move to the regeneration site. CSGs send MSTs forward to assist in assessment and on-site repairs.


Regeneration may be required when normal operations or reorganization cannot sufficiently restore attrited units to the desired level of combat effectiveness. Regeneration may require --

  • Replacing the chain of command.
  • Assistance from higher echelon.
  • Reestablishment of C2.
  • Assessing unit effectiveness.
  • Large-scale infusion of personnel, equipment, and supplies.
  • Mission essential training.
  • Time to reestablish unit cohesion.

FM 100-9 provides guidance to commanders and staff who provide CSS in support of regeneration operations. It describes reconstitution planning, decision making, and execution. The corps administrative/logistics order and COSCOM/CSG OPORD and logistics estimates provide more specific details on responsibilities and execution time lines.


The echelon commander, at least two levels above the attrited unit, with the resources to perform regeneration approves and controls regeneration. An uncommitted division could control regeneration of a battalion, provided significant corps assets augment the division RTF. However, when divisions are committed, the corps or TA commander controls regeneration of battalions. The corps needs TA assistance to regenerate a brigade. Even with TA help, it may not be able to regenerate certain types of brigades, such as an aviation brigade.

The corps G3 has overall staff responsibility for planning and coordinating regeneration. The corps commander may elect to not regenerate an attrited unit in order to use resources elsewhere in the corps. Once the corps issues the regeneration order, attrited units are attached to the corps. This prevents the parent division from cross-leveling critical assets from degraded units for use elsewhere in the division. The corps remains in charge of corps units during regeneration, regardless of where regeneration physically takes place.


Corps headquarters predesignates an RTF. The corps commander activates an RTF following his decision to regenerate units, battalion(s), or a brigade.

The corps commander and staff task organize the RTF. It includes both CSS elements and operations elements. The composition of the RTF remains METT-T driven. FM 100-9 lists a sample RTF.

CSG Elements to the RTF

While RTF operations elements focus on reestablishing C2 and conducting individual and collective training, CSG subordinate elements provide the required supplies, equipment, transportation, and services to regenerate attrited units. Those subordinate elements may also provide life support, to include rations, water, and power generation, for RTF elements at the regeneration site. CSGs could be tasked to provide the following elements to the RTF:

  • DS Maintenance Elements/MSTs.
  • TMDE Team.
  • AVIM Forward Support Platoon or Teams.
  • Medium Truck Platoon/Truck Company Assets.
  • Trailer Transfer Team.
  • HET Truck Platoon.
  • Heavy Materiel Supply Platoon.
  • DS Supply Company Elements.
  • Ammunition Supply Platoon.
  • GS Petroleum Supply Platoon.
  • Medium Truck (Petroleum) Platoon.
  • CEB Teams.
  • Water Teams, if required.
  • Mortuary affairs collection points.

CSG support operations section staff officers identify subordinate CSB elements whose mission work load declines when the units they support are pulled off line. These elements could be attached to the RTF CSG support operations staff officers help coordinate logistics support at the regeneration site.

CSB Role

Rather than piecemeal an ad hoc headquarters from various units, the corps commander could designate a CSB HHD to provide S-staff support for the RTF. The CSB's coordinating staff coordinate life support (rations, billeting, and perimeter security) for personnel and elements attached to the RTF. CSB OPORDs detail how CSB HHD staff support regeneration site operations.

CSB subordinate elements could form the nucleus of logistics regeneration assets. The CSB could require augmentation to perform the logistics portion of regeneration. While the CSB supports the regeneration mission, other missions performed by CSB elements is disrupted. The CSG support operations officer changes the customer support lists, directing that units obtain support elsewhere. He also coordinates with the CMMC and CMCC and servicing MCT on reconsignment of inbound cargo.


RTF assessment element staff and representatives assess and select regeneration sites. They plan and coordinate the evacuation of attrited unit assets to the site. RTF assessment personnel prioritize and develop time frames for the flow of supplies, field services, HSS, maintenance support, and replacement personnel to the regeneration site.

Depending upon regeneration requirements, established support areas could be selected as possible regeneration sites. Time and distance factors may influence the RTF to select sites within the forward CSG AO. In that case, the rear CSG provides backup support. Rear CSG units throughput fuel, supplies, and equipment to the regeneration site, while forward CSG units establish supply points to receive and issue stocks. Forward CSGs also provide MSTs, CEB teams, and laundry teams, as well as movement support assets.

MSTs suggest field expedient repairs to enable recovery and evacuation of combat damaged equipment to the regeneration site. CSG elements also provide refuel-on-the-move and other critical assistance to degraded units at link-up points on the unit line of march to the regeneration site. For example, attrited units could obtain adequate munitions on their way to the regeneration site, either from their supporting ATP or from a nearby ATP or ASP. Other units provide support as attrited units move through the CSG's AO on the way to the regeneration site.


CSG support of regeneration depends on requirements, priorities, and time available. The corps G3 determines priorities of support. The RTF orchestrates its execution. Logistics elements in the RTF rearm, refuel, and refit attrited units. Once the RTF and attrited units reach the regeneration site, logistics support of regeneration is similar to normal support operations. Support differs only in the quantity of support required, the priorities of support, and the time available to provide support. As attrited units withdraw to regeneration sites, CSG support operations staff officers make tradeoff decisions as they arrange to reallocate assets no longer providing support forward to those units.


Field feeding personnel accompany the RTF advance party. They serve hot meals, preferably T, B, or A Rations and provide sundry pack comfort items, as attrited units arrive at the site. The RTF should have limited contract authority to arrange for Class I augmentation and ice from HN resources. Limited local purchase authorization should also be granted.

Class I points and water points provide rations, sundry packs, and water both to attrited unit personnel and to personnel of the RTF. The Class I point replenishes the unit basic load of MRE and T Rations. It provides Class VI items, if available in the theater. Water point personnel provide water purification and issue.

Class II points send MOPP gear and decontamination solutions to the initial rest site, if required. Assessment teams should have identified requirements for lost or damaged OCIE.

Field services units send teams to provide CEB and laundry support. These teams accompany the RTF advance party. The RTF coordinates the use of chemical latrines with the HN.


Attrited units obtain enough munitions from their supporting ATP, another ATP, or ASP to enable them to move to the regeneration site. Small arms munitions could also be issued at the link-up point.

RTF munitions staff submits requirements to the ASP or CSA. Requirements include sufficient munitions to secure the regeneration site and train on new weapon systems as well as replenish attrited unit basic loads.

The CMMC directs the issue or redistribution of stocks from a CSA or ASP to the regeneration site. The DAO, CMMC, and CMCC coordinate to redirect stocks which were to be moved to the ATP supporting units now removed from combat.

An element from a DS conventional ammunition company sets up at the regeneration site. Second shift personnel from an ASP or CSA could travel to the regeneration site to receive and issue munitions. The RTF coordinates MHE requirements. Munitions inspectors are needed to evaluate ammunition stocks brought back by attrited units.


A subordinate Class III point may provide refuel-on-the-movesupport or arrange to provide bulk fuel at a predetermined link-up point.

RTF fuel personnel obtain fuel allocation instructions from the corps or TA. The area MCT redirects shipment of bulk fuels from DS stocks. The CMCC provides prioritized shipping instructions to move fuel to the regeneration site.


The RTF/CSG directs subordinate units to provide assistance in assessing, recovering, and evacuating items to the regeneration site. The RTF establishes priorities for recovery repair, and cannibalization.

If required. AVIM forward support platoons or teams go forward to the attrited units to assess the airworthiness of aircraft. They perform expedient battle damage repairs using BDAR kits to bring damaged aircraft to a flyable condition. When this is not possible. ground and air assets assist in recovering and evacuating damaged aircraft to the rear. If large numbers of aircraft require repair, the regeneration site should be near an AVIM site, if feasible.

The RTF may send MSTs to the link-up point to perform immediate battlefield repairs. MSTs use expedient repairs to enable equipment to move to the regeneration site or a maintenance collection point.

DS maintenance units provide recovery assistance as well as master mechanics, tools, test equipment, components, and repair parts. Maintenance personnel set up a recovery/evacuation point at the regeneration site to facilitate movement of reparable items. They replenish PLL items and perform controlled exchange. The RTF approves cannibalization of battle loss major end items.

COSCOM maintenance support branch staff/CMMC commodity managers need to recompute ASL/PLL packages to match the new mission and new organizational structure of the regenerated force. The CMMC performs intensive management of critical Class IX items. It performs a lateral search for needed repair parts and identifies substitutions. The repair parts supply company ships parts to RTF maintenance elements.

Maintenance companies already designated as a ALOC unit could receive shipments of critical repair parts by air. The CMCC coordinates for air movement of critical repair parts. The CMCC is the committal authority for Army aviation assets allocated for CSS air movement operations. It is also the validator for Army requirements for Air Force airlift.


Regeneration focuses on returning weapon systems to battle. The RTF may have priority for corps war reserve stocks. When inoperable and battle-damaged equipment cannot be repaired within time limitations, heavy materiel supply company personnel need to offload and deprocess war reserve stocks. They prepare replacement items ready-for-issue. HETs or rail cars move the weapon systems to the regeneration site. Weapon systems arrive at the regeneration site fueled and with ammunition on board. Crews then boresight/zero weapons.

The weapon systems manager, COSCOM weapon systems support branch chief, coordinates weapons replacement with corps personnel group staff. The CMMC assists in locating items needed to make a complete system. These may include radios, thermal sights, communications security devices, machine guns, and basic-issue items.


Truck units provide truck assets to assist in recovery of attrited unit assets. They help move supplies, equipment, and personnel to the regeneration site. HETs may be needed to move replacement end items to the regeneration site.

A truck unit maybe part of the RTF to move equipment and supplies within the regeneration site. This unit also supports movement of attrited units after regeneration. The RTF forwards requirements for external lift assets through the supporting MCT to the CMCC.

The CMCC plans routes into and out of the regeneration site adequate to accommodate the anticipated volume and type of traffic. If routes are not adequate, the CMCC identifies requirements for upgrading and coordinates for engineer support. The CMCC coordinates requirements for transportation support and commits transportation assets. It assists with movement regulation into and out of the site.

An MCT coordinates the move to the regeneration site. The area MCT forms the critical link between the CMCC, mode operator, shipper, and receiver. CSB transportation branch personnel coordinate movements within the regeneration site. If required, they coordinate with HN or allied nation transportation activities and requests additional support as needed. After regeneration is completed, they coordinate the onward movement of units with the supporting MCT. They also coordinate the retrograde of inoperable equipment.


Due to the lethality of modern battle and threat targeting of critical logistics sites, subordinate units and battalions may also require regeneration support.

CSG staff officers assist subordinate unit commanders in assessing regeneration requirements. They assess the impact which loss of transportation or maintenance units will have on supply distribution systems. The CSG support operations officer changes repair authorizations and supply stockage levels. CSG and subordinate battalion staff provide the RTF assessment element with status on the areas identified on Table D-1.

Subordinate battalions report C2 requirements through command channels. They assess the remaining mission capabilities of subordinate attrited units. They report supply and equipment status through S4 channels to the CSG's S3.

Once the corps G3 approves regeneration, subordinate elements withdraw to a designated regeneration site or safe site out of sector. The RTF coordinates with the CMCC for additional transportation assets to move units to the regeneration site. The RTF may need to request TA movement assistance. If necessary, the RTF coordinates for decontamination en route to the regeneration site.

Low density mission equipment is difficult to replace or repair. Class VII items are often available only in war reserves. Cross-leveling equipment provides a temporary means of returning units to acceptable levels. While there are multiple DS supply units, DS maintenance units, and truck units within a CSG or COSCOM, there are certain units which are one-of-a-kind units within each CSG. These include the --

  • Heavy materiel supply company.
  • Repair parts supply company.
  • Mortuary affairs collection company.
  • Ordnance missile support company.
  • HAWK maintenance company.
  • Airdrop supply company.
  • Airdrop equipment repair and supply company.

Low density MOSs are difficult to replace. CSG and subordinate battalion personnel may help cross-train replacement personnel who have the critical MOS as a secondary MOSs.
