Fixing the Force

Success on future battlefields may depend on which side can recover, evacuate, repair, and return damaged and disabled weapon systems to the fight faster. Where opposing forces possess parity in the number and destruction capability of weapon systems, the force which can repair and return the greater number to battle gains the advantage. For this to happen, maintenance units need to maintain sufficient stocks of the right repair parts. Maintaining stockage of high demand items ensures immediate response to supported customers. Maintaining critical replacement end items helps ensure combat readiness when maintenance cannot repair items within established time limits.















DS maintenance units repair and return equipment to the using unit. The number and types of units supported affect the number of DS maintenance units attached to a CSB. They also impact on the number and type of repair teams augmented to support unit-unique equipment. Figure 9-1 shows a group's DS maintenance support organization.


Nondivision DS maintenance units (TOE 43209L000) provide DS maintenance and repair parts supply. They support nondivision units on an area basis. They also provide reinforcing maintenance support to division maintenance units. This includes augmenting FSB and MSB maintenance units which provide support to corps FA, corps air defense, and corps engineer battalions. Augmentation includes MSTs with appropriate skills and tools and additional maintenance personnel to offset work loads or operate additional MCPs. These MSTs form a habitual support association with FA battalions.

The company normally maintains an ASL of approximately 5,000 lines of repair parts. This includes about 500 lines of reparable items. The ASL supports the combat PLLs of supported units. It serves as the principal source of parts replenishment of PLL stocks. Supported units pick up repair parts and reparable items at the supporting maintenance company.

The theater commander may attach a classification and collection element to the corps from a COMMZ C&C company. Until then, DS maintenance companies operate a C&C point in addition to a maintenance collecting point.

The CSG attaches DS maintenance units to CSBs in forward and rear CSGs. They provide area support for units within or passing through their assigned support area. They also make up for shortfalls in the organic DS maintenance capability of divisions. For more information, refer to FM 43-11 and the DS maintenance unit MTP.


Each DS maintenance unit has four organic MMTs. These teams perform on-site malfunction diagnosis and battle damage assessment. Their primary objective remains rapid forward repair by component replacement. However, MMTs also adjust, align, repair, and replace modules and end items. They can repair selected items. Examples include wheeled vehicles, power generation equipment, small arms, and field radios. The Class IX stored in each of the team's repair parts vans may be designed to support peculiar equipment or specific CS units on site at remote areas.

Depending upon work loads, a mobile maintenance team (TOE 43509L0) may be allocated, in addition to the four MMTs authorized in the base company, to perform essential maintenance on automotive, communications, small arms, and power generation equipment for corps FA, ADA, and engineer battalions required to maneuver in divisional forward areas.

The CSB tailors these teams to meet the specific needs of the unit requesting support. MMTs may be task organized as MSTs to support single organizations for the duration of specific operations. MMTs may be employed intact or tailored to support unique requirements or a specific mission and deployed as MSTs. For example, an MMT could be tasked to provide reinforcing support at a FSB maintenance unit in support of additional work loads from corps forces in the brigade area. MMTs could be tailored to provide support at a forward logistics element. They could also accompany a task force to support corps forces employing in a non-US Army corps or in support of an ally or sister Service.

When repairing on site, team personnel depend on the supported unit for security, rations, and quarters. The supported unit also provides Class III supplies and lift capability. The parent unit continues to provide administrative support.


Maintenance teams (TOE 43509LA00-LR00) augment nondivision DS maintenance units. They provide maintenance on low-density equipment. They also support units deploying forward into division areas. The number and types of repair teams augmented depend upon the density and types of low-density equipment supported.

Employment also depends on the tactical situation. Augmentation maintenance teams support from either the base DS maintenance company area, an MCP in the corps or division area, or on site at the supported unit's position. They may employ as far forward as the BSA. The supported unit provides ration, fuel, and billeting. The CSB employed in the division area provides a central point of coordination for teams employed in a division sector.

When the supported unit moves out of the supporting DS maintenance unit's area, the CSG can attach the team to another supporting DS maintenance unit. The MST draws support from the maintenance unit to which they are attached. The gaining DS maintenance unit provides Class IX repair parts for the repair team.

MST assets are established by TOE/MTOE. They may be augmented by the supporting logistics commander based upon METT-T. Equipment transferred with the team includes those items authorized to that particular team. General shop sets or the set of special tools or test equipment used by base shop personnel would not go with the team. The MST uses the base shop assets of the nondivision maintenance unit in the new AO.

If the supported organization is deployed out of sector, the accompanying MST receives Class IX supply support from the nearest DS maintenance unit, to include the nearest FSB maintenance unit. Prior coordination between supported corps brigade S4s and COSCOM support operations staff ensures that unique repair parts for supported unit systems are added to the ASL of the nondivision maintenance unit in the new AO. The pace of offensive operations requires that the COSCOM plan to use air transportation to replenish unique repair parts required by MSTs.


The Repair Parts Supply Company, GS (TOE 42419L000) provides GS repair parts and maintenance related Class II items to division and nondivision DS maintenance units. Situation dependent, it maintains a 15-day stock of Class IX for ALOC units and 30 days of Class II (maintenance related) and Class IX for ALOC units. The TOE lists mission capabilities. FM 42-119 describes field operations. The unit's MTP covers critical mission tasks.

The COSCOM normally attaches the repair parts supply company to the rear CSG'S S&S battalion. Since it remains far less mobile than most corps units, this company could set up operations in factory buildings or warehouses in built-up areas. It could also setup in HN commercial storage facilities.


AVIM ensures the maximum number of flyable aircraft to support combat forces. Aircraft density and anticipated percentages of passback from division AVIM units determine the number of AVIM units attached to the rear CSG's aviation maintenance battalion. They also affect the number of aircraft repair parts supply platoons attached to a repair parts supply company. Figure 9-2 depicts the rear CSG's AVIM support organization.


Aviation companies (AVIM) (TOE 01947L100-800) provide aviation intermediate maintenance for corps assigned aircraft. They also provide reinforcing AVIM support for division aircraft maintenance companies.

Each heavy division AVIM company may transfer 25 percent of its work load to a supporting nondivision AVIM company. Light infantry division AVIM companies pass back even greater percentages. FM 1-500 describes how AVIM units provide this reinforcing support. AVIM battalion maintenance officers cross-level work loads between nondivision AVIM units or request augmentation. Units evacuate avionics equipment which exceed corps AVIM unit capabilities to maintenance facilities in the COMMZ or CONUS.

Nondivision AVIM units employ in the corps rear area, normally in or adjacent to an instrumented landing facility. As needed, the AVIM battalion task organizes elements from AVIM units into maintenance, repair, or recovery teams. These teams perform specific missions, usually for a short period of time. At the end of the mission, the teams return to the AVIM unit.

AVIM companies also provide aviation DS repair parts supply support to corps aviation units. This includes aircraft armament and avionics. AVIM companics also provide reparable items for selected high usage components required by AVIM units.

TOE 01947L100 lists mission capabilities. The unit's MTP describes its mission tasks in detail.


The group may attach augmentation elements (TOE 01547L000) to the AVIM unit. This depends on the type of units and equipment requiring support. These elements do not normally employ forward into the division's AO. However, they can help to reduce division AVIM backlogs. Development of combat maintenance/battle damage repair kits and procedures help streamline repair and recovery procedures.


When augmenting a repair parts supply company, the Aircraft and Repair Parts Supply Platoon (TOE 42519 LA) provides GS level supply of aircraft repair parts. The platoon maintains a 15-day stock of Class IX aircraft repair parts. The platoon can receive, reware-house, and ship 22 STONs of aircraft repair parts per day. It has a total handling capability of 66 STONs a day. Allocation is one platoon per AVIM battalion.

To reduce dependence on corps transportation assets to deliver aircraft repair parts, the platoon may collocate with an AVIM company normally operating near an airfield. The AVIM company provides C2, ADP, communications support, food service, unit supply, and unit maintenance support to the platoon.


Missile maintenance elements attached to a CSB vary depending on the type and density of missile systems supported. FM 9-59 describes the missile maintenance company organization. Figure 9-3 shows a CSG's missile maintenance organization.


The missile support company is organized under TOE 09428L000. It provides DS missile maintenance and missile repair parts for air defense and land combat support systems, except HAWK and PATRIOT missile systems. Repair consists primarily of replacement or exchange of reparable items.


Based on the type of supported battalions and the density of missile systems supported, the CSG assigns these teams to the missile support company. TOES 09528LB-LV and 09510LA list the mission capabilities for each team. The teams go forward to perform BDAR and on-site repair and replacement. They may accompany MLRS battalions that deploy in support of divisions. Others may go forward to the brigade trains area to provide reinforcing support to divisions. Some teams perform DS missile maintenance in the base shop.

The teams depend on the missile support company for specific support. This includes technical supply, maintenance quality control, and major TMDE shop sets. The supported unit provides unit level administration, field feeding support, unit supply, and unit maintenance.


An Ordnance Company (DS), HAWK (Corps) (TOE 09497L000) maybe attached to the rear CSG's CSB. This company provides DS maintenance to a HAWK battalion for HAWK-peculiar equipment.

The unit can requisition, receive, store, and issue 5,000 lines of repair parts for the HAWK missile system. This includes reparable items and associated air defense identification friend or foe systems. It also includes associated power generation and air-conditioning equipment.

As needed, this company provides MSTs to supported units. If required, a HAWK maintenance augmentation team (TOE 09529LU) can provide GS maintenance support for HAWK missile system peculiar equipment.


The PATRIOT maintenance company, organized under TOE 43607L000, provides DS maintenance and Class IX repair parts supply to a PATRIOT ADA battalion. A PATRIOT missile system (DS/GS) augmentation team (TOE 09529LX) can provide additional MSTs and maintenance support to PATRIOT missile-peculiar equipment.


Conventional ammunition companies perform conventional ammunition maintenance. Airdrop equipment repair and supply companies repair airdrop equipment. However, CSGs depend on other organizations for maintenance of COMSEC materiel, office ma chine equipment, rail materiel, and watercraft.


DS and GS conventional ammunition companies perform conventional ammunition maintenance. This ensures that ammunition stocks are serviceable and restores unserviceable stocks to a serviceable condition.

Both DS and GS conventional ammunition companies perform DS maintenance and limited modification on conventional ammunition, components, and containers. Maintenance functions include --

  • Repairing containers.
  • Removing rust.
  • Cleaning, restenciling, reboxing, and repalletizing.
  • Performing limited modification.

Ammunition requiring more extensive maintenance may need to be demilitarized, destroyed, disposed of, or evacuated to an appropriate maintenance activity.

Due to their focus on ammunition issue and receipt operations, forward employed DS conventional ammunition companies may perform only limited packaging and preservation functions. They clean, paint, and remark containers or replace broken banding on packages. FM 9-38 describes unit operations.


The COSCOM may attach an Airdrop Equipment Repair and Supply Company (TOE 10449L100-200) to the rear CSG's S&S battalion. This company provides DS maintenance on airdrop equipment. Maintenance personnel repair cargo parachutes, personnel parachutes, airdrop containers, harnesses, slings, and other textile airdrop items.

When organized under TOE 10449L100, the company supports a Quartermaster airdrop supply company and other corps units requiring airdrop equipment support. When organized under TOE 10449L200, it provides airdrop equipment maintenance in support of an airborne division and attached units. FM 10-400 describes how to set up maintenance support operations.


Nondivision DS maintenance units can provide CE equipment repair. However, CSG units depend on supporting signal units for additional COMSEC DS maintenance support. The corps area signal company has a C-E maintenance section. The CSG C-E officer coordinates requirements for COMSEC maintenance between the corps area signal company and maintenance units attached to the group's subordinate CSBs.


Office Machine Equipment Maintenance Teams (TOES 42550LA, LB, and LC) may augment CSB DS maintenance companies. These teams perform DS repair on office machines, except electronic calculators and accounting equipment.


The HN or transportation rail companies attached to a railway battalion provide maintenance for rail equipment. The Railway Equipment Maintenance Company (TOE 55228H800) performs repairs on locomotives and rail cars. The Railway Engineering Company (TOE 55227H800) performs repairs on rail track, bridges, and structures.


Requirements for watercraft maintenance depend on the use of ports, harbors, inland or coastal waters, or open seas. A Floating Craft GS Maintenance Company (TOE 55157H600) attached to a transportation terminal battalion provides GS maintenance on amphibians and landing craft and DS and GS maintenance on harbor craft used in waterborne tactical operations or joint amphibious operations. It also issues marine peculiar repair parts.


Maintenance operations increase the combat readiness of supported units. Weapon systems damaged in battle must be repaired and returned to the battle as soon as possible. Sufficient repair parts need to be on hand to support the combat PLLs of supported units and support DS level maintenance without resulting in excessive deadlined equipment and backlogs.

Figure 9-4 depicts a maintenance support structure on a battlefield.

  • MSTs employ as far forward as possible. The CSG attaches MSTs to corps units to perform BDAR and on-site repairs using replacement modules. Habitually assigned MSTs for a corps FA battalion accompany the battalion to a new division area and out of sector. The actual composition of habitually assigned MSTs are derived by MARC data in the Total Army Analysis process. Depending upon the type of supported unit artillery systems and work loads, accompanying MSTs may include --

  • Track vehicle repair team, TOE 43509LC00
  • Self-propelled FA turret/fire control repair team, TOE 43509LD00.
  • TACFIRE repair team, TOE 43509LQ00.
  • Mobile maintenance team, TOE 43509L000.

  • Situation dependent, the forward CSG liaison officer coordinates reinforcing support for corps FA, air defense, or engineer battalions from FSB maintenance units.
  • CSBs along the route of march provide maintenance support and recovery assistance.
  • Nondivision DS maintenance and AVIM units provide reinforcing maintenance and recovery and evacuation assistance to divisional maintenance and AVIM units.
  • The repair parts supply company provides repair parts resupply for DS maintenance companies.
  • Replacement end items from the heavy materiel supply company help ensure combat readiness when maintenance cannot occur within established time limits.


Repairs occur as far forward as the tactical situation allows. This helps minimize recovery and evacuation time and reduces the drain on transportation assets. A nondivision maintenance unit employs in the division area to support corps units. Repair teams from that unit may augment FSB and MSB support to corps forces, providing BDAR on site or at the MCPs in the BSA or DSA.


Repair teams employed in forward battle areas perform BDAR. They assess battle damage and the amount of repairs and repair time required to return mission essential items to combat. If possible, they fix the essential items as quickly as possible. They jury-rig components to restore minimum essential systems. CSG maintenance branch personnel ensure that BDAR efforts focus on the critical equipment or weapon systems required for a specific combat mission.


Each maintenance unit establishes an MCP. The MCP should be easily accessible to supported units. CSB maintenance branch personnel recommend locations for the MCP operated by the nondivision DS maintenance unit. Supported units recover the item to the nearest MCP. Corps FA, air defense, and engineer battalions recover items to the MCP operated by the nearest FSB maintenance unit. Inspection personnel at the MCP determine whether repairs can be performed by the FSB maintenance unit or supporting CSB maintenance unit within set time limits.


Units recover items to a location where repairs can be made or evacuation begins. The owning unit or unit which finds abandoned equipment has primary responsibility for recovery. Using units authorized recovery assets recover inoperable or abandoned items to an MCP or along an MSR. As time and the tactical situation permit, DS maintenance units clear the MSR of inoperable or abandoned vehicles. When required, DS maintenance units provide limited, reinforcing vehicular recovery following procedures in FM 20-22.

If the DS maintenance unit provides reinforcing recovery, the owning unit needs to provide information on the --

  • Type of equipment recovered.
  • Extent of damage.
  • Location of the item.

When specific location information is not available or friendly lines are undefined, the supported unit needs to provide ground guides.


Supporting AVIM units provide reinforcing aircraft recovery support to AVUM platoons. FM 1-500 prescribes aircraft recovery responsibilities, recovery methods, and safety precautions.


Evacuation efforts depend on the time and resources available and the availability of damaged and unserviceable equipment. Truck units evacuate equipment to the correct level for repairs. CSGs lateral truck assets to ease evacuation efforts in sectors where damaged equipment is creating backlogs on MSRs. To ensure the most efficient use of limited unit recovery or battalion evacuation assets, the COSCOM support operations officer establishes priorities for evacuation.

CSG maintenance branch personnel ensure that units evacuate reparable weapon systems and other urgently needed items first. The CMMC provides disposition instructions for items which either exceed repair time guidelines or are not economically reparable at the DS level. It coordinates evacuation requirements with the CMCC.

Unless the situation prevents it, units complete unit level maintenance before evacuating the item to the DS maintenance unit. The accompanying maintenance request form indicates whether repair parts were still due out at the time of evacuation.

DS maintenance units help supported units evacuate unserviceable items to an MCP or property disposal facility, as appropriate. They evacuate unserviceable items beyond DS maintenance capability to the supporting GS maintenance unit in the COMMZ. To prevent damage to the item intransit, both using units and DS maintenance units evacuating unserviceable reparable material need to provide adequate packaging and preservation.

Before evacuating items for GS maintenance, CSG maintenance branch officers coordinate with the CMMC to verify that the item is on the theater army list as reparable at GS maintenance. CMMC maintenance materiel managers provide disposition instructions. They indicate the maintenance effort required prior to evacuation of items for overhaul or salvage. The extent of maintenance performed depends on the tactical situation and time available.


AVUM platoons evacuate aircraft to the supporting AVIM unit only as a last resort. Instead, AVIM teams go to the aircraft to perform repairs beyond the AVUM level. Evacuation from AVUM platoon to AVIM units occurs when aircraft require extensive airframe repair. The CMMC coordinates the evacuation of aircraft between supporting maintenance activities.


AR 710-2 and DA Pamphlet 710-2-2 prescribe reparable management, stockage criteria, and procedures. Customer units turn-in unserviceable reparable to their supporting DS maintenance or AVIM unit and request serviceable replacements. The maintenance unit forwards a copy of the receipt document to the CMMC for posting to accountable records.

Maintenance units maintain replacement reparable as part of their ASL. DS maintenance units maintain up to 550 lines of reparable items. AVIM units maintain up to 750 lines. Depending on stock availability, the DS maintenance or AVIM unit issues a serviceable for unserviceable reparable as an immediate over-the-counter issue.

Customer units need to have a valid reason why an unserviceable turn-in is not available. Possible valid reasons include --

  • Initial issue.
  • Increased stock levels.
  • Lost or damaged items.
  • Temporary loan to allow the customer unit to obtain packing material to use to return unserviceable items.

When serviceable or substitute reparable are not available to fill a low priority request, the maintenance unit work orders the unserviceable reparable to maintenance. It processes the request as a due-out. When returns from repair or dues-in can not meet the customer unit's required delivery date, maintenance units process a high priority request. They can also work order the unserviceable item to maintenance as a high priority.

If necessary, the maintenance unit ships the unserviceable reparable to the maintenance unit designated on the CMMC reparable items return list. The CMMC issues repair instructions. Maintenance unit personnel report repaired items to the CMMC. They report items which they cannot repair to the CMMC for disposition instructions.


AR 750-1 prescribes maintenance float policy, procedures, and controls. Maintenance floats help maintain the readiness posture of units during peacetime. They replace like items turned in by using units which need an immediate replacement. They help maintain an acceptable level of materiel readiness during peacetime. Both DS maintenance and AVIM units may maintain an ORF of selected Class VII items.

Upon outbreak of general hostilities, the CMMC directs that nondeployed units use ORF items to enhance equipment readiness or fill shortages in specific combat units. ORF items fill initial battle losses.

CSG OPLANs include procedures for accepting ORF assets during mobilization. Plans include provision for augmenting DS maintenance units with an ORF Maintenance Team (TOE 43509LL).


Controlled exchange consists of the removal of serviceable parts, components, assemblies, and subassemblies from unserviceable, economically reparable items to restore a like item to a mission capable condition. To ensure a complete end item, maintenance personnel reinstall unserviceable parts and components on the unserviceable reparable item.

Units perform controlled exchange on an exception basis. CSG/COSCOM maintenance support branch personnel determine that DS maintenance units cannot obtain required parts either through the supply system, lateral supply, or local procurement. Maintenance personnel check the supply suspense file to ensure that parts are not due in within the time frame indicated by the PD on DA Form 2407. The DS maintenance or AVIM unit shop officer authorizes controlled exchange in coordination with the owning unit. CSG maintenance branch personnel monitor controlled exchange to prevent abuse.


Cannibalization refers to the authorized removable of serviceable parts from items authorized for disposal. Units cannot cannibalize an item until disposition instructions from the CMMC direct or permit cannibalization. CSG maintenance branch staff ensures that cannibalization activities support priorities and comply with CMMC disposition instructions.

Like controlled exchange, cannibalization supplements supply support or reparable management actions when parts are not immediately available. Cannibalization provides a source of supply for --

  • High priority requirements when the supply system cannot meet the RDD.
  • Authorized low mortality or difficult to obtain repair parts, components, and assemblies.
  • Items not stocked in the supporting unit ASL.

The corps G4 establishes wartime cannibalization policy. For example, materiel destroyed to prevent enemy capture should first be cannibalized. The COSCOM and CSG OPORDs restate the corps policy on limited cannibalization. Based on the combat situation, the COSCOM may require that the group establish decentralized cannibalization points. AR 710-2 and DA Pamphlet 710-2-2 prescribe policy and procedures for setting up and operating cannibalization points.


For the force to remain combat ready, maintenance units need to maintain sufficient stocks of repair parts. They maintain an ASL of repair parts (including reparables) to issue to supported units for unit level maintenance.

CSG supply and service branch personnel monitor the repair parts supply system for items in short supply. They ensure compliance with issue priorities, As necessary, they recommend cross-leveling repair parts within subordinate units and expedite repair parts delivery.


Repair parts stockage depends on criteria in AR 710-2. The ASL depends upon demands, mission changes, order ship time, and equipment fielding. The ASL serves as the source of parts for replenishment of PLL stocks. It covers supported units' combat PLLs. Because of a low demand for certain items during peacetime, maintenance units maintain certain combat load ASL items without demand.

If attachments of units require that supporting DS maintenance units support different types of equipment, the CMMC needs to identify the density of this equipment and the required Class IX support. The CMMC needs to load this data into the management system to preclude rejection of requisitions.


Local purchase provides an alternate source of supply for repair parts. CSG procurement personnel approve local purchase of repair parts to satisfy the following conditions:

  • To support contingency operations when the operation is imminent or in progress.
  • When the expected delivery date will not satisfy requirements.
  • When the repair part is not listed on the AMDF.
  • For rejected requisition items with a status code of CW or CP.


The term "common repair parts" refers to those repair parts which are not used to repair aircraft or missiles. As shown by Figure 9-5, the requisition and distribution flow for common repair parts depend on whether the repair parts are --

  • TA controlled.
  • For DA-designated ALOC units.
  • Not airlift eligible due to weight or size.


Units submit DA Form 2765-1 requests to their supporting DS maintenance unit. If the DS maintenance unit cannot fill the request, it transmits a requisition to the CMMC. DS maintenance units also submit a requisition to the CMMC when the reorder point is reached.

The CMMC receives requisitions from DMMCs as well as from DS maintenance units. The CMMC searches its stockage lists to determine if the part exists in the corps rear area. When the part is available, the CMMC cuts an MRO directing the repair parts supply company to issue the item to the supporting DS maintenance unit. When the part is not available, it transmits a requisition to the TAMMC. The CMMC transmits requisitions for ALOC designated units to the applicable CONUS NICP. It transmits requisitions for TA controlled repair parts to the TAMMC.


For DA-designated ALOC units, Class IX and Class II maintenance-related air-eligible items are shipped via ALOC. Army air clearance authority approves items for air shipment. CONUS consolidation and containerization points consolidate and containerize items for each ALOC DS and GS activity. Once ALOC is fully established, repair parts arrive almost daily at aerial ports of debarkation. Repair parts are delivered directly to the DS maintenance unit for issue to the requesting unit.

Oversized and heavy Class II and IX items are transported by rail and truck from seaports. Surface delivered repair parts are transported from a TAACOM repair parts supply company to either the corps' repair parts supply company or the supporting DS maintenance unit. The postal system may even be used to supplement delivery of repair parts. If repair parts are urgently needed, the CMCC arranges to have high priority repair parts delivered by air.


The supporting DS maintenance unit informs the supported unit that the repair part is available for issue. Supported unit supply personnel drive to the DS maintenance unit's supply platoon site for the repair part. When corps organizations move to another area, the ship to DODAAC can be changed to the new supporting maintenance unit. That maintenance unit could be an MSB Light or Heavy Maintenance Company or FSB Maintenance Company. Forward CSG's liaison officers coordinate support arrangements.


Figure 9-6 depicts the requisition and distribution flow of aircraft and missile repair parts. The flow depends on whether the parts are controlled by TA, required by DA-designated ALOC units, or delivered by surface means.


Units submit requests to their supporting AVIM unit, missile support company, or DS HAWK company. If the part exists in the supporting unit's ASL, and is not TA controlled, the supporting unit issues the part. Supported unit personnel go to the AVIM or missile support company to get the part. Aircraft or missile maintenance augmentation teams could also deliver repair parts to supported units in the division sector.

When the part is not available, the supporting maintenance unit transmits a requisition to the CMMC. Depending on whether the repair part is controlled or an air eligible item, the CMMC --

  • Transmits a requisition for TA controlled items to the TAMMC.
  • Transmits a requisition to the applicable CONUS NICP for air eligible items requested by ALOC designated units.
  • Cuts an MRO directing the applicable company to issue the aircraft or missile repair part.


Aircraft and missile repair parts are distributed to the applicable AVIM unit, missile support company, or DS maintenance HAWK company.

Corps units may receive support from an MSB Missile Support Company or FSB Maintenance Company's Missile Maintenance Repair Section. The forward CSG's liaison officer coordinates support arrangements with the MSB/FSB.


There are times when maintenance units cannot repair damaged end items within set time limits. Efforts to replace combat equipment losses or unserviceable end items depend on how the CMMC processes the items. The CMMC processes end items under normal Class VII replenishment and distribution or as intensively managed items. Figure 9-7 depicts the requisition and distribution flow for Class VII end items.


The logistics annex to the CSG/COSCOM OPORD lists corps and TA controlled Class VII items. Requests for intensively managed items require command approval. Units request command approval concurrently with submission of their requests. Requests flow through command channels.

After command approval, the CM MC prepares an MRO directing the heavy materiel supply company or DS supply company to release the item. The CMMC coordinates with the CMCC for movement support. The GS supply company or DS supply company coordinates transportation support requirements with the supporting MCT.

Battalion and group support operations supply staff monitor the number of command controlled Class VII items issued, due out, remaining, and due in.



Nondivision units submit requests for Class VII items to their supporting DS supply company Class II, IV, and VII point. To facilitate the flow of Class VII major end items, units can submit off line battle loss reports to the CM MC. The CMMC initiates a requisition and tracks the requisition to ensure it is issued against the unit. Current TOEs/MTOEs serve as the requisitioning authority.

If the end item is on hand, the DS supply company issues the item. When the end item is not on hand, the DS supply company forwards a requisition to the CMMC.

The CMMC receives requisitions from DMMCs and separate brigade and regiment MMCs as well as from DS supply companies. The CMMC performs a lateral search to determine if the end item is available within the corps rear area.

If the end item is on hand, the CMMC cuts an MRO directing issue from the heavy materiel supply company attached to the S&S battalion. If the item is not on hand, the CMMC passes the requisition to the TAMMC. The TAMMC either directs issue from a TAACOM heavy materiel supply company or transmits the requisition to the appropriate CONUS NICP.

Receipt and End Item Processing

The heavy materiel supply company's processing sections deprocess incoming combat-tactical vehicles at or near the port of entry. Battalion supply staff officers ensure that enough MHE is available to process shipments. They relay guidance on the priority of equipment to be processed.

Processing section personnel visually inspect incoming vehicles to determine if damage occurred during shipment. Items which cannot be repaired by the heavy materiel supply company's unit level repairers are evacuated to a DS maintenance unit.

Processing section personnel install, inspect, and test any communications equipment mounted on combat-tactical vehicles or special-purpose vehicles.


Heavy materiel supply company personnel process end items ready-for-issue to the supporting DS supply company or link-up point. This means that they install ancillary equipment. They lubricate equipment and provide a full fuel load. They ensure that basic issue items are onboard all vehicles and equipment.

Ammunition specialists assigned to the equipment storage platoon determine the amount and type of basic ammunition load required. They request and pick up or arrange for delivery of basic load ammunition for combat vehicles.


When items are ready for shipment, the heavy materiel supply company's supply operations office notifies the CMMC. The CMMC informs the CMCC of transportation requirements. The supporting MCT coordinates pick up and delivery to the supporting DS supply company or to a link-up point in the division support area. The heavy materiel supply company ensures that towed vehicles are attached to the appropriate prime movers and that they are in proper convoy position when shipped. A regeneration task force MCT coordinates movement to a regeneration site.

Nondivision units pickup Class VII items at their supporting Class VII supply point. The CSB LO arranges for corps FA, corps air defense, or corps engineer organizations in the brigade area to pickup Class VII items at the FSB's Class VII yard. There is no stockage of Class VII items at the FSB. Class VII items are delivered to the FSB on an on-call, marked-for, and ship-to basis.

The receiving unit provides the driver and crew for replacement vehicles. However, it is less desirable to have combat-tactical vehicles or special-purpose vehicles driven under their own power. The preferred method is to use HETs to transport weapon systems and end items to a link-up point. This ensures that systems arrive operationally ready. Less fuel is consumed en route. Crews arrive rested and prepared to fight.


Table 9-1 lists areas which CSG maintenance branch personnel should consider when planning maintenance support of offensive, defensive, and retrograde operations.


CSG maintenance branch personnel need to identify commonalities among vehicles and equipment. This helps them to later assess the possibility of cross-leveling repair parts and performing expedient repairs to restore mission capability or enable equipment to move to an assembly point.

Maintenance policy should require that task force elements carry additional tow bars to help in recovery operations. Units recover items one terrain feature back or to the nearest MSR.

MSTs set up an MCP to provide rapid repairs before the maneuver unit crosses the line of contact. CSG maintenance branch personnel tailor MSTs and adjust the reparable items which MSTs take with them to the equipment in the attacking force. Orders limit repairs to rapid repair and replacement of components. They can increase sup port of offensive operations use of controlled exchange through approving maximum and authorizing cannibalization.


For defensive operations, the focus shifts to evacuation and repair. Maintenance units sometimes extend repair times. The CMMC and CSG can change the maintenance priority of affected units. For example, repair priorities may shift to support the tactical combat force organized to counter a Level III threat.

CSG S2/S3 and maintenance branch staff officers try to ensure that repair teams avoid entering areas where units are in contact. They also ensure that repair teams avoid using roads prioritized for the TCF or MP response force.

With ground LOCs secure, corps truck assets throughput repair parts to the lowest level able to receive supplies. CSG maintenance officers request that the CMMC expedite requisitions for critical repair parts.


During retrograde operations, DS maintenance and AVIM units deploy to the rear before combat forces. CSG transportation branch personnel arrange for evacuation of unserviceable reparable items on railcars (if available) or trucks. Time permitting, CSG maintenance branch officers direct that maintenance personnel cannibalize items which need to be abandoned or destroyed in order to prevent enemy use.


Excessive maintenance backlogs remain perhaps the predominant concern. CSG maintenance branch personnel monitor ASL size and depth. They assess its effect on mobility, demand satisfaction, and equipmentdeadlines They also need to monitor the misuse of replacement end items to resolve maintenance support problems.

Movement of supported units into or out of the maintenance unit's geographic support area results in imbalanced work loads and maintenance backlogs.

When indicators warrant concern, CSG maintenance branch personnel conduct daily site visits to subordinate maintenance units. They assess problems or trends and recommend corrective actions to group and battalion support operations staff. To help resolve maintenance backlogs, CSG maintenance branch personnel recommend --

  • Changing customer lists.
  • Reinforcing FSB maintenance units with mechanics, tools, and recovery assets.
  • Using truck assets in the CSB to push major assemblies forward to FSB MCPs for pickup by MSTs.
  • Cross-leveling repair parts.
  • Local purchase of tools and repair parts.
  • Using controlled exchange.
  • Authorizing cannibalization.


ASL size and depth should provide responsive support to customer units yet not impede mobility. CSG units can maintain the following ASL:

  • Nondivision DS maintenance units maintain up to 5,000 lines of repair parts.
  • AVIM units maintain aviation unique repair parts.
  • The missile support company maintains up to 4,500 lines of missile repair parts.
  • HAWK DS maintenance units maintain up to 5,000 lines.
  • Repair parts supply companies maintain up to 20,000 lines of common repair parts.

ASL Depth

Maintenance units support on an area basis. Therefore, their ASL needs to support a diversity of type of units employed in or moving through their area. The CMMC adjusts deployment ASLs to cover the combat PLLs of supported units. The CMMC adjusts ASLs when the corps pulls supported units off-line for reconstitution and another type unit takes its place.

Peacetime stationing of maintenance units with FA brigades ensures that the ASL reflects maintenance requirements to maintain and repair unique major weapon systems -- 155-mm towed howitzer, 155-mm self-propelled howitzer, and MLRS. Establishing this peacetime habitual relationship depends on the Capstone trace and TPFDL.

CSG maintenance branch personnel periodically review ASL change lists to ensure that subordinate maintenance units stock only essential items. They review deletions recommended due to low demands in view of requirements for unit unique items, future operations, and seasonal changes.

ASL Mobility

All DS maintenance and AVIM units should maintain 50 percent mobility. Units store combat essential ASL lines on repair parts vans. Using railroad boxcars to transport storage bins of repair parts reduces the shortfall of prime movers.


CSG supply staff continually assesses demand satisfaction. AR 710-2 recommends that supporting units strive for 70 to 80 percent demand satisfaction. Monthly supply performance reports produced by current automated systems list the percent of demand satisfaction. Separate pages cover common repair parts, aircraft repair parts, and missile repair parts. Supply performance reports alert CSG S&S branch staff to problem areas. These may include --

  • Warehouse denials.
  • ASL lines at zero balance with dues-out.
  • ASL lines at or below safety level.
  • Overuse of high PDs.


CSG maintenance branch personnel resolve critical equipment deadlines by --

  • Verifying that subordinate units transmitted a high priority NMCS request to the CMMC.
  • Coordinating lateral issues among subordinate units.
  • Recommending obtaining parts by using local purchase or controlled exchange procedures on a like item
  • Directing units to cannibalize unserviceable end items to obtain required parts.


To control maintenance support, maintenance branch personnel recommend and revise maintenance priorities. Repair priorities help ensure that maintenance units repair critically needed items first. CSG maintenance branch personnel also control support by ensuring that maintenance units comply with repair time limits. They monitor maintenance support by analyzing status reports and performing assistance visits and staff inspections.


The corps G4 sets repair priorities. CSG/CSB maintenance branch personnel ensure that subordinate maintenance units comply with repair priorities. First priority normally goes to repair and return critical weapon systems to combat units. Normally, maintenance units repair combat vehicles before tactical vehicles.

When recovery and evacuation assets are limited, CSG maintenance branch personnel recommend that COSCOM maintenance support branch staff officers revise priorities. They allow backlogs of nonessential items in order to concentrate repair efforts on critical items.


The theater commander prescribes wartime maximum repair time limits. To help prevent maintenance backlogs, repair time guidelines are set for each level of maintenance. The COSCOM support operations officer establishes repair time limits for corps maintenance units. Repair times appear in the service support annex to the OPORD. The CSG maintenance management officer recommends that the COSCOM maintenance support branch adjust repair times based on the --

  • Tactical situation.
  • Maintenance backlog.
  • Availability of repair parts.
  • Order ship time.

CSG and CSB maintenance branch personnel continually monitor repair times. This helps to ensure that maintenance units evacuate jobs which may exceed the prescribed time limits.

A suggested guideline for repair in the DSA is 36 hours. The suggested time for the corps area is 96 hours. If authorized, controlled exchange and cannibalization help keep repairs within time guidelines. Use TB 43-0002-3 to help control the extent of maintenance performed on specific Army aircraft items.


Status reports enable CSG and CSB maintenance branch personnel to monitor the adequacy of maintenance support in their area. Each maintenance unit reports on --

  • Recovery assistance capability.
  • Evacuation capability.
  • Shortage of maintenance MOSs.
  • Backlog (in man-hours).
  • Status of critical items awaiting repair.
  • Critical repair parts.
  • Quantity of items requiring evacuation.
  • Overall mission capability.
  • Problem areas.

CSG and CSB maintenance branch personnel monitor backlog data and recommend ways, to include HNS and local purchase, to eliminate excessive backlogs and resolve shortages of repair parts.


Battalion work load summaries provide a means to monitor and control backlogs in maintenance units. Table 9-2 provides a sample. CSG and CSB maintenance branch personnel review battalion work load summaries to assess potential problems created by personnel and equipment shortages. To reduce backlogs, the CSG maintenance management officer recommends cross-leveling work loads or evacuating to another DS maintenance unit.


Laterally transferring equipment between subordinate maintenance units helps control maintenance backlogs and reduce repair times. Equipment transferred between maintenance units or subordinate battalions should meet the equipment transfer standards prescribed in AR 750-1.


CSG maintenance branch personnel visit supported and supporting units to provide technical assistance and resolve maintenance support concerns. Subjects discussed during these visits may include --

  • Problems encountered in obtaining or providing required support.
  • Future operations which may increase requirements for DS maintenance and repair parts supply.
  • Adequacy of repair parts supply procedures.
  • Adding reparable items.
  • Adjusting the ASL to cover the combat PLL of new customer units.
  • Requirements for technical assistance.
  • Ways to hold reports to a minimum.
  • Current priorities.
  • Projected needs for replacement mechanics, augmentation maintenance teams, and special tool sets.


CSG and CSB maintenance branch personnel conduct staff inspections of maintenance support operations in DS maintenance units. During staff inspections, maintenance branch personnel review files to determine the number, type, and frequency of repairs. They discuss repair times and ensure that supporting maintenance units correctly report maintenance status.


CSG and CSB maintenance branch personnel continually monitor maintenance work loads and requirements to ensure that they do not exceed the maintenance capability of subordinate maintenance units. They concentrate on determining the cause for backlogs and recommending corrective actions to ensure timely maintenance support.


TAMMS records prescribed by DA Pamphlet 738-750 provide a potential source of managerial data. SAMS forms and procedures replace some TAMMS forms. CSG/CSB maintenance branch personnel should highlight areas on each form which they want to check on during site visits.


As shown by Figure 9-8, SAMS-1 supports maintenance reporting requirements at DS maintenance, AVIM, and DS missile maintenance units. It tracks work orders, repair parts, and processes requests from supported units. SAMS-2 collects and retrieves maintenance data from SAM S-1 sites. It allows maintenance staff at CSBS, CSGs, the COSCOM and CMMC to analyze and coordinate maintenance work loads, DA Pamphlet 738-750 describes SAMS forms and procedures.


SAMS-1 interfaces with ULLS for maintenance request reporting. SAMS-1 also interfaces with SARSS-1. This enables DS level maintenance unit supervisors to monitor Class IX repair parts supply.

ble equipment, equipment backlogs, and maintenance/asset performance reports.

The interface between SAMS-2, SARSS-2A, and CSSCS, enables CMMC managers and CSG repair parts technicians to obtain data on Class IX requisition status and make management exception decisions.

SAMS-2 enables CSB maintenance branch personnel to monitor maintenance shop performance and manage reparable and shop stock or bench stock. CSG maintenance branch personnel use the CSSCS interface with SAMS-2 to --

  • Monitor and adjust maintenance work loads and backlogs.
  • Identify repair sections with a higher than acceptable backlog.
  • Monitor NMCS work requests.
  • Pinpoint problem areas.
  • Analyze causes for deadline equipment.
  • Determine materiel status and materiel readiness.
  • Monitor the responsiveness of the repair parts supply system.
  • Monitor the adequacy and use of reparable items.
  • Determine the status of MWOs.
  • Monitor urgent MWOs which influence materiel readiness.
  • Monitor calibration.


To continue to provide maintenance support in an NBC environment, subordinate DS maintenance units need to avoid or contain contamination. CSG and CSB S2/S3 section personnel provide staff assistance on ways for subordinate maintenance units to avoid or contain contamination and protect recovery and maintenance personnel.


Maintenance efforts are constrained by contamination and the requirement to work in MOPP gear. In an NBC environment, subordinate maintenance units need to set up an inspection point, contaminated equipment holding area, and contaminated as well as clean MCP areas. SOPS set forth inspection procedures, contamination controls, and protection measures.


Owning units decontaminate items prior to recovery and evacuation to a subordinate DS maintenance unit. Units use contaminated vehicles to recover contaminated equipment to a decontamination site or contaminated MCP. Onboard decontamination apparatus should be used to spray those surfaces which recovery personnel need to touch. CSB maintenance branch personnel need to request deliberate decontamination assistance from COSCOM/corps chemical units.


DS maintenance personnel should treat all equipment as contaminated. Vehicles and equipment decontaminated to a negligible risk level for operators and crews can still be a hazard to mechanics. Chemical contamination becomes trapped in closed assemblies, bolt threads, and petroleum products. Hazardous vapor collects in air filters. The chemical agent alarm or chemical agent monitors authorized by TOEs alert maintenance personnel of the presence of vapor hazards and trapped chemicals.


To contain contamination, all vehicles, equipment, and personnel pass through an inspection point before entering the maintenance area. Inspectors send uncontaminated equipment to the clean MCP area. They direct contaminated equipment to a contaminated holding area.


Corps decontamination organizations perform deliberate decontamination operations. The CSG NBC officer arranges for corps chemical units to provide hasty and deliberate decontamination support.

Maintenance personnel should assume that equipment known to have come from a contaminated area is contaminated. FM 3-5 describes decontamination techniques in general. FM 1-102 provides specific guidance for aircraft decontamination.


It is difficult to decontaminate equipment to present only minimal risk to mechanics. They should wear MOPP4 gear to repair previously contaminated vehicles. Oil, grease, and dirt degrade the protective qualities of chemical overgarments. Therefore, CSB S4 staff need to ensure that extra MOPP gear is on hand. Fuel handlers' aprons, field expedient rubber qualities of chemical overgarments. Therefore, CSB S4 staff need to ensure that extra MOPP gear is on hand. Fuel handlers' aprons, field expedient rubber sheets, and wet weather gear help keep MOPP gear clean. However, they increase heat buildup.


Depending on criticality of need, maintenance personnel in MOPP4 gear may need to repair some contaminated end items. DS maintenance unit supervisors set aside an area for repair of contaminated items. Contaminated tools and equipment remain in the contaminated MCP area.

CSB maintenance branch personnel ensure that supervisors schedule periodic withdrawal of maintenance personnel from the contaminated MCP area to the clean MCP area.


Maintaining an MCP area free of contamination provides a place where maintenance personnel can work in reduced MOPP gear. This provides relief from the psychological and heat stress associated with wearing MOPP gear. Modified MOPP1 or 2, in which the gloves are worn, may be appropriate.
