Why are fortifications often camouflaged or concealed?

In military science, fortifications are camouflaged or concealed to protect defensive positions and personnel from enemy observation and attack. By masking installations, equipment, and activities, military forces aim to defeat enemy intelligence efforts, which forces the adversary to divert significant resources and personnel toward increased surveillance.12

The primary objectives of this concealment include:

• Deception: Providing false visual information to confuse the enemy, potentially leading to indecision, wasted time, and strategic errors.1
• Protection: Making weapons, vehicles, and structures indistinguishable from the surrounding terrain to prevent targeting by aerial reconnaissance or long-range bombing.1
• Strategic Advantage: Allowing defenders to maximize the effectiveness of their own weapons while preventing the enemy from utilizing their resources to their best advantage.2

Techniques range from passive measures—such as using natural foliage, netting, and dull-colored paints—to active deception, including the use of decoys and dummy installations to draw enemy fire away from real targets.1
