Supporting the COSCOM

In addition to providing control and staff supervision for achieving the COSCOM's external logistics support missions, the COSCOM headquarters also includes the staff to control and supervise the 8,000 to 22,000 soldiers assigned, attached, or placed OPCON to COSCOM units. General and special staff officers oversee the health, welfare, morale, training, and discipline of assigned and attached personnel. This chapter covers the mission and functions and the staff responsibilities of those staff elements of the COSCOM headquarters concerned with internal support of COSCOM soldiers.













The COSCOM headquarters is organized under a G-staff organization shown on Figure 9-1. This aligns the COSCOM's general staff with the coordinating general staff officer sections in the corps headquarters.


Special staff officers provide professional and specialized technical assistance to COSCOM headquarters staff and to the staff of subordinate commands.

The chaplain, COSCOM surgeon, IG, SJA and PAO serve as members of the COSCOM commander's personal or special staff. Other personal staff includes the commander of the headquarters, special troops battalion, the command sergeant major, and aides. They work under the immediate control of the COSCOM commander and assist him directly.


Coordinating general staff officers focus on the internal support requirements of personnel in subordinate COSCOM units. Table 9-1 lists their areas of support. Though general staff officers respond to the chief of staff, they retain full authority to act on matters within their functional area. They keep the COSCOM commander informed of internal support problem areas which impact upon accomplishment of the COSCOM's external logistics support mission. They resolve problems reported by their counterpart staff officers in subordinate commands.


The COSCOM commander may include any or all of the personal, special, and coordinating general staff officers within his staff. As long as his staff remains within MTOE authorizations, the COSCOM commander can integrate or realign elements to save resources and promote responsiveness of support. To do this, his ACofS, G3 submits requests according to AR 310-49 through command channels to the MACOM requesting reorganization and realignment of personnel.

If the COSCOM headquarters will be the senior logistics headquarters, it must be augmented with staff officers for those areas in which it lacks staff technical expertise.


Special staff officers provide command level expertise and assistance in specialized, technical, or professional areas to COSCOM headquarters staff and staff in subordinate commands. The ACofS, G1 section provides administrative support to special staff sections.


The COSCOM staff chaplain serves as a special/personal staff officer on the COSCOM commander's staff. He advises the COSCOM commander on the command's religious programs. He develops, coordinates, and implements the COSCOM religious support plan. He is also the corps staff chaplain's primary supervisor for religious support in the corps rear area, He implements the corps staff chaplain's religious support plan. The COSCOM staff chaplain --

  • Exercises technical control and coordination over COSCOM unit UMTs.

  • Coordinates and executes general and direct religious support for personnel and units in the corps rear area.

  • Performs and provides religious support to COSCOM headquarters personnel and other unit personnel in the COSCOM AO without organic UMT support.

COSCOM Unit Ministry Team

The COSCOM UMT implements the corps rear area support plan for the corps rear area. It closely monitors changing battlefield conditions and unit locations through the coordinating staff briefs and daily religious support status reports received through technical channels. A means of communication may be through the rear operations net to and from UMTs in bases. Battalion level UMTs respond to the requirements of the COSCOM UMT. They submit their requirements through the CSGs and the medical brigade/group UMT to the COSCOM UMT. The COSCOM UMT maintains close and continuous communication with the corps UMT and coordinates with allied and civilian religious leaders in the COSCOM area of responsibility.

General Religious Support Plan

Because of the large number of units and detachments in the corps rear area and the wide dispersion of these units, the COSCOM UMT develops and implements a comprehensive general religious support plan. Execution of this RSP provides religious support to all units in the corps rear area. Continuously changing unit configurations due to battlefield conditions, necessitates constant coordination of adequate religious support to all soldiers. The COSCOM UMT continually reviews and updates the corps chaplain's RSP in accordance with battlefield changes and UMT variations.

The corps rear area general RSP is developed and implemented as follows --

  • Each UMT in the corps rear area assesses unit missions and locations and develops an RSP.

  • Their RSPs are consolidated and coordinated through technical channels with the COSCOM UMT.

  • The COSCOM staff UMT provides data on units without assigned UMTs and the unit UMTs add general religious support coverage to the RSPs.

  • Supervisors submit revised RSPs to the commander for approval.

  • The COSCOM staff chaplain designates each CSG UMT as coordinator for general religious support in his area.

The consolidated and coordinated general religious support plan at the CSG level --

  • Lists units and detachments located within the support group area.

  • Identifies the number of chaplains located in the support group area, by denomination and unit assignment.

  • Specifies general religious support coverage responsibilities.

  • Identifies shortfalls, if any, in chaplain personnel and supplies.

They provide advice concerning the population of the AO, to include local customs, institutions, economy, and government. They also conduct surveys and studies on obligations between civil and military authorities, to include treaties, agreements, conventions, international law, and US policy.

Section personnel also identify potential civilmilitary problems that may directly affect COSCOM operations. They prepare estimates of the probable political, economic, and social impact of military operations and recommend courses of action to exploit CA interfaces and their working relationships with the local population. They supervise the collection of contraband, arms, and ammunition in the AO. As required, they coordinate with ACofS, G3 operations branch personnel on the use of PSYOP to persuade indigenous populations to cooperate with COSCOM staff.


CA units or elements perform a command support mission for the COSCOM. The corps may allocate CA teams to COSCOM units in either general or direct support roles. CA units attached to the COSCOM's headquarters, special troops battalion and not further attached to subordinate commands are OPCON to the ACofS, G5. CA units attached to the headquarters, special troops battalion provide augmentation assistance, as required, to the ACofS, G5 section to aid in planning CA operations. FMs 41-5 and 41-10 describe the mission and functions of CA units or teams.

The scope of CA units or CA teams assigned or attached varies depending upon the AO and level of combat activity. CA support to the COSCOM might include --

  • Conducting area studies and reviewing HNS agreements.

  • Identifying available local resources, facilities, and support.

  • Developing CA annexes to COSCOM OPLANs.

  • Providing input to the troop information programs on culturally appropriate behavior.

  • Coordinating US requirements for and assisting in the acquisition of local resources, facilities, and support.
