The sustainment brigade is deployed to an operational theater to provide sustainment to designated forces within a command specified area. The supported command’s Operations Order (OPORD) directs the sustainment brigade to provide/coordinate for support to specified forces during the deployment on an area basis. The Human Resources Operations Branch (HROB) within the Support Operations (SPO) Section has the responsibility to plan, coordinate, integrate, and manage the emplacement and operations of subordinate HR elements in synchronization with the concept of support plans for casualty, PA, and postal operations, throughout the area of operations. The commander has issued planning guidance that the brigade may be required to perform as theater opening element then shift to theater distribution role. Unit Standing Operating Procedures (SOPs) are available. The section has appropriate connectivity to both Non-secure Internet Protocol Router (NIPR) and Secret Internet Protocol Router (SIPR) Networks and access to all automated personnel systems. Technical guidance is received from the Human Resource Sustainment Center (HRSC) and higher headquarters SPOs, as appropriate. Communications are established with subordinate, adjacent units and higher headquarters. Command and control information systems are operational and passing information in accordance with Tactical Standing Operating Procedures (TSOP). Threat capabilities include information gathering, hostile force sympathizers, and terrorist activities in a Chemical, Biological, Radiological, Nuclear and high yield Explosives (CBRNE) environment. Some iterations of this task should be performed in MOPP 4.
