Which three modes of transportation does the DoD rely on in peace and war, and whose mission provides them?

• A. Air, Land, and Sea; Joint Chiefs'
• B. Air, Land, and Sea; USTRANSCOM's
• C. Air, Space, and Sea; USAF's
• D. Land, Sea, and Space; DoD's

Answer: (B)

Understanding how the DoD moves personnel and materiel across air, land, and sea and who provides that capability is what this item tests. The DoD relies on three primary modes of transportation to project and sustain forces in both peace and war: air, land, and sea. Coordinating and delivering those movements across the globe is the mission of United States Transportation Command (USTRANSCOM). USTRANSCOM brings together the service transport components—Air Mobility Command for airlift and related air operations, Military Sealift Command for strategic and afloat sealift, and the Military Surface Deployment and Distribution Command for land distribution—to plan, synchronize, and execute mobility operations under a single authority. This unified command ensures rapid, reliable movement of people, equipment, and supplies wherever needed, across all theaters and missions.
