COSCOM MAINTENANCE OPERATIONS
The COSCOM's maintenance system is a combat multiplier. It ensures corps units remain operationally ready for war. It also repairs and returns corps weapon systems and equipment to battle or provides replacements for battle losses. COSCOM DSM units repair and return damaged or disabled equipment to their using units. Whenever possible, they send MSTs forward into the division sector to repair damaged or inoperable equipment onsite. When weapon systems or other major end items are destroyed, the COSCOM's heavy materiel supply unit provides a class VII battle loss replacement.
The COSCOM tailors its DSM organization with the primary focus to repair and return weapon systems to the battlefield quickly. The COSCOM will use its class VII supply system to provide battle loss replacements to those units that can most influence the corps battle.
REINFORCING MAINTENANCE
Each nondivisional DSM unit can provide four organic mobile maintenance teams to perform onsite reinforcing maintenance, malfunction diagnosis, and battle damage assessment. These teams may be task organized into appropriate MSTs to provide reinforcing maintenance to other DSM units. The MMC assigns these reinforcing MSTs to weigh the maintenance effort or to better use available maintenance assets. The reinforcing MSTs are located with and supported by the DSM unit they are reinforcing.
The COSCOM/CSG will attach repair teams (MSTs) to DSM units to support units or task forces deploying forward into divisional areas, provide specialized maintenance on low-density equipment, support reconstitution, or provide reinforcing maintenance capabilities. When the COSCOM designates a corps DSM unit to provide maintenance to a division, it must augment that unit with the appropriate MSTs to perform the additional maintenance work load.
OTHER CORPS MAINTENANCE CAPABILITIES
The COSCOM's DS missile maintenance sustainment organization consists of those elements necessary to support the corps. The actual support structure will depend on the system-unique missile systems requiring support. The elements attached to a maintenance battalion will vary due to the types and density of supported missile systems.
The COSCOM's heavy materiel supply company provides class VII battle loss replacement items. This company can receive, store, and issue 1,400 STON of GS-level class VII items per day. It maintains storage sites for COSCOM war reserve class VII stocks. Upon receipt of the end items from a TAACOM storage site, heavy materiel supply company personnel will deprocess the items. As necessary, they will ensure weapon systems are ready for issue and link them up with a replacement crew.
Owning units recover unserviceable equipment to the MCP established by their supporting DSM unit. Based on METT-T, DSM units may provide recovery and evacuation assistance. Owning units also recover aircraft. However, the AVIM unit responsible for the area where the aircraft is located may provide backup support. Evacuation begins at the MCP, and evacuation is coordinated between maintenance, supply, and transportation elements. The COSCOM will evacuate items not repairable at the DSM units to GSM units in the COMMZ. The COSCOM MMC will provide disposition instructions to damaged equipment. As appropriate, the DISCOM or COSCOM will coordinate the transportation required to support evacuation operations.
COSCOM MMC MANAGEMENT
The COSCOM MMC provides routine day-to-day maintenance management IAW guidance and direction COSCOM support operations furnish. It focuses COSCOM maintenance resources on repairing and returning critical weapon systems to their users. Officers assigned to the commodity-oriented maintenance management branches of the COSCOM MMC will analyze and manage all aspects of repair, readiness, and supply of their respective commodities.
DISCOM MAINTENANCE OPERATIONS
DISCOM maintenance elements operate throughout the division area (see figure 7-3). They typically perform their functions onsite, at MCPs, and at company maintenance shops. Guidelines for time to repair at specific levels are provided for planning purposes, but the ultimate decision concerning maintenance timelines is a command consideration.
a. MMC. The MMC materiel section manages repair parts supply and maintenance. It designs and manages the division class IX inventory and directs class IX issue. The section also monitors unit maintenance throughout the division. It collects, analyzes, and reports maintenance statistics. It records modification work order (MWO) status and compiles reports on the operational status of division equipment. The section also provides disposition instructions on all unserviceable materiel.
b. MSB. The MSB's mission is to provide maintenance support for division and other designated units located in the division rear and reinforcing support to the FSBs. Some of the specific maintenance-related functions provided are division-level supply support for class IX, operating a salvage collection point, the motor transport of heavy or oversized cargo and equipment to the FSBs, and evacuating equipment from forward areas.
c. Light maintenance company. The MSB light maintenance company provides DSM to division units the FSB maintenance companies do not support. It also provides reinforcing maintenance for the three FSB maintenance companies. It provides an ASL of up to 6,000 lines, RX service for selected common repair parts, onsite maintenance support, and COMSEC maintenance for all division units (less signal and military intelligence battalion items). The company, when required, sends MSTs throughout the division area to provide required support consistent with tactical limitations and their support capabilities.
d. Heavy maintenance company. The MSB heavy maintenance company provides DSM to units within the division. This DSM includes ****lworking; machining; and repairing automotive equipment, small-arms and artillery pieces, power-generation items, engineer equipment, fire control instruments, and tank turret systems. This company provides technical and limited recovery assistance to units employed in the division rear. MSTs from the heavy maintenance company provide reinforcing support to the FSB maintenance companies. The company also provides teams to support the cavalry squadron and the MLRS unit located in the division rear.
e. Missile maintenance company. The MSB missile maintenance company provides DSM and missile class IX supply for division missile weapon systems, to include the short-range air defense (SHORAD) system. This includes supporting radars, land combat missile systems, and MLRS. The support includes receiving,
storing, and issuing class IX supplies for land combat, SHORAD, and MLRS systems; tube-launched, optically tracked, wire-guided (TOW)/Dragon class IX and RX supply support; and onsite repair for all missile systems not organic to brigades.
f. AVIM company. The AVIM company is assigned to the division ASB in a heavy division. The ASB is organic to the DISCOM. The company is structured to support the aircraft assigned to the division, specifically, observation, utility, and attack helicopters. It provides the aviation brigade with AVIM and backup AVUM support at its base location in the division rear. The AVIM company's main body, generally located with the aviation brigade, performs extensive on-aircraft systems maintenance, including structural and airframe repairs, repairing components, and performing scheduled AVIM-level inspections. The ground maintenance company in the division ASB maintains the division class IX (air) ASL. This is to replenish supported unit PLL stocks and support AVIM operations. The aircraft maintenance company also employs mobile, weapon system-oriented forward repair/recovery teams to perform authorized intermediate maintenance and BDAR in forward areas. The AVIM company provides limited collection, classification, and recovery of serviceable and unserviceable equipment.
g. FSB maintenance company. The FSB maintenance company is a critical component in "fixing the force." It provides DSM and common repair parts service in each brigade area which now includes the aviation brigade. The company includes a variable number of SSTs that provide tailored support to aviation, tank, or mechanized infantry battalions. The company provides one team for each maneuver battalion assigned to the brigade. The company can provide limited recovery assistance to supported units when required and technically supervises PLL supply for its supported units. It physically maintains a portion of the division ASL to support the items stocked in supported units' combat PLLs.
h. Recovery operations. Recovery operations in armor and mechanized infantry battalions are centrally managed at battalion level, usually by the BMO. The battalion maintenance platoon has recovery vehicles to provide recovery support. The platoon has company maintenance teams, each of which has an organic recovery capability. The recovery mission is assigned to a recovery team that accomplishes the recovery according to unit SOP. Equipment is recovered either to the battalion UMCP or to a designated MCP.
i. Evacuation. Evacuation is from the maneuver battalion UMCP to the FSB's maintenance company MCP in the BSA with its own recovery assets. Evacuation may be by transportation units to the division MCP in the DSA or to a corps MCP. Severely damaged equipment may be evacuated directly from the UMCP to any higher level of maintenance. The G4 sets the overall division evacuation policy in coordination with the DISCOM commander. The DISCOM commander has overall evacuation control, exercised through the DMMC. A DISCOM or COSCOM transportation unit physically evacuates the equipment. This movement is done according to set procedures or in response to disposition instructions from the DMMC.
The DMMC manages the evacuation effort. It acts as the interface between the FSBs' maintenance companies and other CSS elements to the rear of the brigade boundary. Evacuation policies and procedures are set as a matter of SOP. Automatic disposition instructions for certain items prevent undue delay in moving equipment from the brigade to the DSA. Maintenance units request disposition instructions from the DMMC through the support battalion support operations section for items not covered by automatic disposition lists.
Different sources provide the transportation to evacuate equipment. Maintenance unit assets and resupply vehicles returning to the rear may be used in the evacuation process. Those vehicles provided in response to unit transportation support requests are also used. For heavy equipment transportation, the maintenance units depend on the TMT company HETs.
Evacuation vehicles transport unserviceable assemblies and major end items according to disposition instructions from the DMMC. They also may backhaul serviceable assemblies and end items from rear repair activities to the forward maintenance or supply elements. HETs and other cargo vehicles bring major replacement end items forward.
j. Division class IX repair parts.
Ground. The DSUs and the DMMC share class IX supply in the division. The DSUs receive, store, issue, and turn in parts. Supply personnel in the DMMC materiel section manage and account for the class IX inventory. They use demand history and command-directed actions to help them. Customers in the DSA submit their requests directly to their supporting DSM unit. The FSB maintenance company will usually pass requests they can't fill directly to the DMMC. The MSB light maintenance company receives class IX items arriving in the division. This company reports receipt of the items to the DMMC. Items are forwarded to the FSB maintenance company for issue to the user located in the brigade area. All issues are reported to the DMMC to update its records. Turn-ins are handled in the same manner as receipts and reported to the DMMC. Missile class IX items are managed through the MSB missile support company in the same manner.
Air. The ground maintenance company in the division ASB provides repair parts supply for all heavy division aircraft, avionics equipment, and aircraft armament systems. It also maintains the division ASL for class IXA. Normally the division class IXA ASL will contain at least one item for each PLL LIN item in the division. During combat operations, the AVUM platoon leader selects PLL/BDAR items to be available forward at either the combat trains or forward area rearm/refuel point (FARP) for quick repairs.
