In the polar mission example, what is the elevation difference between the observer and the target?

• A. 20 meters
• B. 455 meters
• C. 475 meters
• D. 2300 meters

Answer: (A)

Elevation difference is the vertical separation between the observer and the target. It’s found by subtracting the observer’s elevation from the target’s elevation. In the polar mission example, the target sits only slightly higher than the observer, yielding a 20-meter difference. That small rise is what the diagram indicates, so 20 meters is the correct value. The larger numbers would require a much greater vertical separation than shown, which isn’t depicted in the example. This vertical difference affects line-of-sight and firing data in the scenario.
