Final answer:
Military training routes above 1500 feet are depicted on topographic maps, which use contour lines to illustrate elevation changes and topography, essential for military planning and operations.
Explanation:
Military training routes above 1500 feet are typically depicted on topographic maps. These maps use contour lines to trace the elevation of the terrain at regularly-spaced intervals. In the context of military exercises, such maps are essential for navigation and planning, as they provide detailed representations of the topography. Military strategists can determine the elevation changes, the steepness of climbs, and the possible challenges that might be faced during flight or ground maneuvers.
For example, on a map with contour lines representing elevations of 10,000 ft., 5,000 ft., 2,000 ft., and 1,000 ft., one could easily identify a military training route that maintains an altitude above 1,500 ft. by following the pattern of the contour lines. It allows for a strategic understanding of the terrain, which is crucial for the preparation and execution of military operations, such as the ones shown in Figure 12.2.8, which maps the routes taken by US troops during historical operations.
