To avoid flying over enemy ground forces, plan routes over rugged, swampy, and/or heavily vegetated terrain.

• A. Rugged, swampy, and/or heavily vegetated terrain
• B. Open plains
• C. Urban areas
• D. Desert terrain

Answer: (A)

Using terrain to mask the flight path helps keep aircraft hidden from enemy ground forces. Rugged, swampy, and heavily vegetated areas provide natural cover and obstacles that slow or break up enemy movement, making it harder for ground forces to spot, track, or reach you. This terrain effectively reduces visibility and line-of-sight threats, which is why it’s the best choice for avoiding engagement.

Open plains offer clear sight lines, increasing detectability. Urban areas, while offering some concealment behind buildings, present many threats and complicate navigation and defense. Desert terrain is flat and open with little cover, making detection easier.
