Medical Materiel Management Branch

3-44. The MMMB manages the Class VIII supply system in the division. The branch coordinates and recommends the prioritization of medical supplies and blood products. It also coordinates for the disposition of captured enemy medical materiel. Under the technical guidance of the health service materiel officer of the division surgeon's section, the medical materiel management branch monitors and coordinates Class VIII resupply for division medical units/elements. Using MC4, the MMMB monitors, via an information copy, all Class VIII requisitions submitted from the division to the supporting corps medical CSS company. The MMMB maintains a record of the requisition until it is filled. The MMMB coordinates shortfalls in throughput distribution with the DSS and division support operation section. The MMMB may update priorities with the MEDLOG company to correct deficiencies in the delivery system. The MMMB provides Class VIII situational understanding to the DISCOM staff and the DSS according to the tactical standing operating procedure (TSOP). The MMMB, in coordination with the CHL cell of the DSS, manages the distribution of blood and blood products for division medical units. It also coordinates through the DSS with the G5 for disposition of captured enemy medical materiel.

Maintenance management functions such as planning, scheduling, and supervising internal procedures and maintenance operations are the responsibility of the DSB, DASB, and FSBs.

3-53. The office uses the SAMS as a tool for developing data and reports for maintenance management. The SAMS includes a maintenance control system and MWO accounting procedures. Data to support the SAMS are provided from using organizations, maintenance units, and the US Army Materiel Command. The data is summarized and prepared in the form of reports. These reports are used for management purposes by supported units, maintenance unit commanders, the division support operations, and the DISCOM commander and staffs.

3-54. Each systems-oriented branch manages designated materiel systems end items and selected Class IX items that are critical or significant to the operational readiness of those systems. Each branch has the following responsibilities:

  • Recommends maintenance data requirements and reports formats.

  • Analyzes data and reports (automated and manual). This is done to recognize trends, problem areas, and any other data that create a need for action by the maintenance units and staff elements.

  • Compiles special reports on the status of division equipment.

  • Assists in developing policies and plans for controlling and managing data and reports and suggesting corrective actions.

  • Provides disposition instructions for unserviceable items of equipment that exceed the repair ability or capacity of maintenance support units. This is done together with the property book-Class VII section. Working closely with the DISCOM movement control office, each branch develops transportation requirements for removing such items from the division area.

  • Develops maintenance plans to support projected combat operations. This is done by coordinating with the maintenance units and staffs.

  • Monitors unit maintenance operations and evaluates procedures and use of equipment and personnel.

  • Maintains the status of all MWOs for equipment and recommends the order of completion for MWOs.

  • Coordinates with other division support operations sections of the status of end item supply.

3-55. Through its branches, the office serves as the centralized maintenance management activity for the division. Centralized management takes care of much of the effort related to, but not directly involved in, repair operations. The management effort mainly includes reporting, compiling, and interpreting data as a basis for management decisions.

Armament-Combat Branch

Aviation Branch

3-59. The aviation branch performs materiel management for aeronautical, airdrop equipment, and test equipment that is a part of, or used with, assigned materiel. Equipment includes materiel for aircraft and airdrop, avionics, aircraft armament, and related test equipment.

3-60. The branch supervises aviation maintenance activities. Key activities are the same as listed in the maintenance section above. In the event of aviation maintenance company work overload, the branch along with the support operations branch passes back to the COSCOM. The branch supervises the maintenance of aircraft and applies production control principles and procedures to aviation maintenance systems.

Missile Branch

3-61. The missile branch performs integrated maintenance management for missiles, less the Class V portion of missiles that are managed by the DAO. Missile maintenance includes rockets, guided missiles, ballistic missiles, and target missiles. Also included are missile fire coordination equipment and related special and multi-system test equipment. Test equipment, which is part of or used with assigned materiel, missile launching and ground support equipment, and missile fire control equipment, are also included.


3-62. The DISCOM commander is responsible for the religious program in his unit. The DISCOM UMT is the staff section that provides religious support (RS) to units assigned or attached to the DISCOM. Its primary mission is to advise the commander on RS to elements of the DISCOM. It advises the commander on unit moral and ethical issues and to meet the religious and spiritual needs of the soldiers. It also advises the commander on the role of indigenous religions in the area of operations.

3-63. The team consists of a chaplain and a chaplain assistant. The chaplain provides the clergy related support to the unit. These include worship and prayer services, funeral and memorial services, and in depth grief counseling. The chaplain assistant provides the administrative and logistical management for the team.

3-64. Initially, the UMT develops an RS annex for the DISCOM OPORD/OPLAN. This annex is based upon the division RS plan and the commander's intent. It addresses the priority of RS to the units assigned or attached to the DISCOM. This includes UMT support to medical facilities, actions during mass casualty situations, support to enemy prisoners of war, and planning for worship, funeral, and memorial services.

3-65. During operations, the UMT keeps abreast of the situation by maintaining contact with the DISCOM S1 and S3. Through FBCB2, the UMT can receive calls for RS directly from units through the religious support call for support FBCB2 screen.

3-66. Because the team is small and the mission sensitive, it is critical that the commander allow the UMT as much autonomy as possible. This will provide the most responsive and effective support to the soldiers.
