Engineering Support to CSS Operations

Operational-level engineer units maintain a support/coordination relationship to theater-level CSS functional assets. The engineer command (ENCOM), as the Army senior engineer commander, provides general engineering support throughout the theater. This support extends from the communications zone (COMMZ) to well forward into the corps rear area. The numbers and types of operational-level engineer units depend on the size of the support base required, host nation (HN) infrastructure, the mission, the availability of existing engineer support in the theater, and perceived threat in the rear area. See FM 100-7 for more details.



A-1. The senior engineer commander task organizes echelon above corps (EAC) assets to best satisfy the priorities of effort and support established by the joint force commander (JFC). Within the COMMZ, the commander aligns engineer assets to provide general support (GS) on an area basis, as they receive service support on an area basis from the CSS community. Current and evolving doctrine would place an engineer brigade in direct support (DS) to the TSC, with subordinate engineer groups in DS to the area support groups (ASGs).



A-2. In accordance with JCS guidance, the JFC establishes broad standards and policies for theater construction that guide engineer operations, whether they are performed by Air Force, Army, or Navy units. They are based on coordinated planning by construction representatives from all service components. Theater construction policies establish standards, priorities, and the theater construction management structure. The JFC may retain control at his level or delegate construction management to a regional contingency engineering manager (RCEM). When the Army is the RCEM, the senior engineer commander, usually the ENCOM commander, performs this function. The RCEM manages all construction, repair, and facility modifications in the COMMZ. This structure provides centralized control and decentralized execution. The RCEM also manages all troop, contract, and HN construction repair operations in the COMMZ. Such a structure ensures that theater construction assets are employed according to JFC-established priorities and policies.



U.S. Army Corps of Engineers (USACE) theater elements provide technical real estate guidance and advice to the theater commander. In addition to recommending real estate policies and operational procedures, they acquire, manage, dispose of, administer payment for rent and damages, handle claims, and prepare records and reports for real estate used within the theater.



The JFC has overall responsibility for real property maintenance activities (RPMA). He normally delegates authority to the ASCC/ARFOR, who may further delegate to the TSC. The TSC and installation commanders (in most cases an ASG) normally provide the needed RPMA support. Principal RPMA in AO includes operation, repair, and maintenance of facilities and utilities; fire prevention and protection; and refuse collection and disposal. RPMA requirements that exceed the CSS organization's capabilities are forwarded to the local senior engineer commander (in most cases, the engineer group providing support to an ASG on an area basis) or USACE element for execution according to theater priorities. The TSC provides technical RPMA guidance to subordinate CSS organizations. The subordinate CSS organizations provide RPMA support to all Army facilities in the theater, including leased facilities unless HNS is available for leased facilities.



In addition to his common staff responsibilities, the senior engineer commander advises the commander on environmental issues. He coordinates with other staff offices to determine the impact of operations on the environment and helps the commander integrate environment considerations into the decisionmaking process.
