Where is illumination typically planned in defensive operations?

• A. In front of the line
• B. On the flanks
• C. At the command post
• D. Behind troops silhouette

Answer: (D)

Illumination in defense is arranged to make attacking movement visible while keeping your own positions as concealed as possible. When light is placed behind the troops’ silhouettes (relative to the expected enemy direction), advancing enemies walk into a bright backdrop, turning them into clear silhouettes against that light. This makes their movement easy to detect and engage, while the defenders stay largely in shadow, preserving concealment of exact positions. Lighting in front would expose and reveal the defenders, lighting on the flanks can create unnecessary exposure or mislead detection, and lighting the command post would give away where decisions are being made.
