The strategic mobility triad is composed of which elements? The correct answer is c) Pre-positioning, airlift, and sealift. These three components are essential to a nation's ability to project and sustain military forces globally. Pre-positioning involves storing military equipment and supplies at strategic locations around the world to ensure rapid availability. Airlift capability allows for the rapid movement of troops and equipment by air, whereas sealift refers to the transportation of goods and vehicles by sea, which, while slower, can move far larger quantities of material. The strategic mobility triad ensures that military forces can be quickly and efficiently mobilized and deployed to respond to crises or conduct operations anywhere in the world.
