Barricade Natural is defined as:

• A. Artificial walls around the magazine
• B. Fences and gates used around the site
• C. Dense timber that blocks line of sight to the magazine
• D. Natural terrain features such as hills or dense timber that cannot be seen from the magazine when trees are bare of leaves

Answer: (D)

Barricade Natural means using the landscape itself as a shield to hide or protect a magazine from observation. It’s about natural terrain features that block the line of sight, not man-made barriers. Hills or dense timber create a physical screen that prevents someone from seeing the magazine from the outside, which is why this option fits—the emphasis is on natural features rather than walls, fences, or artificial constructs. The note about trees being bare of leaves underscores that the protection comes from the terrain itself, not from seasonal foliage, reinforcing that it’s the natural landscape that serves as the barricade.
