scope:

Purpose. This regulation establishes policies and procedures associated with the multimodal components of the Department of Defense (DOD) Transportation Engineering Program that includes the highways, railroads, and ports for national defense programs. This regulation implements DOD Directive (DODD) 4510.11. It provides guidance and procedures on obtaining installation transportation engineering studies (evaluations of marine ports, terminals, and other modal facilities) and transportation engineering guidance related to DOD force transportation/deployment. The DOD Engineering for Transportability and Deployability Program, also included in DODD 4510.11, has its own implementing regulation and therefore is not discussed further in this document.

Applicability. This regulation applies to all Department of Defense (DOD) Services, agencies, and activities involved in the movement of military personnel, equipment, or other material at military installations or over the national defense transportation network, either as an executive or participating Service (hereafter referred collectively as the "DOD components"). During mobilization, procedures in this publication can be modified to support policy changes as necessary.
