The Defense Transportation System (DTS) is that portion of the worldwide transportation infrastructure that supports Department of Defense (DOD) transportation needs in peace and war. It consists of two major elements: military (organic) and commercial (nonorganic) resources. These resources include aircraft, ships, barges, rail and road assets, pipelines, services, and systems organic to, contracted for, or controlled by DOD. DTS infrastructure, including seaports, aerial ports, railways, highways, pipeline pumping and terminal stations, automated information systems, as well as supporting services, such as in-transit visibility (ITV), customs, and traffic management, are vital elements of the DOD capability to project power worldwide. Global transportation management (GTM) refers to an integrated process that includes coordinated efforts in the planning, programming, budgeting, and execution process, development of unified or coordinated management procedures and systems for deliberate and crisis action planning, and application of DOD and civil transportation systems through exercises, operations, and centralized traffic management.
