Modern means of transport alone cannot eliminate the strategic significance of terrain, environment, and vast distance, and the challenge is compounded by the twin tyrannies of time and cost. The ability to engage globally and decisively in a timely manner depends on the mobility and transportation assets U.S. Transportation Command (USTRANSCOM) coordinates and synchronizes. The command works closely with the components, the Defense Logistics Agency, and commercial partners to overcome geographical constraints and rapidly project power through global mobility, assured access, a viable Global Distribution Network, and global synchronization of distribution.
