What is defined as protection from enemy observation?

The concept of protection from enemy observation is best encapsulated by the term "concealment." Concealment involves using natural or artificial elements in the environment to hide personnel, equipment, or positions from enemy sight. This is crucial in military operations to maintain the element of surprise, protect troops, and enhance tactical advantages.

In contrast, "cover" refers to protection from enemy fire rather than observation. While cover can provide concealment, its primary function is to shield forces from being directly harmed. Other terms like "blindness" and "deception" do not accurately describe the act of hiding from observation. Blindness could imply making an enemy unable to see, but it doesn’t reflect the tactical use of the environment to obscure visibility. Deception involves misleading the enemy through tactics or false information rather than physically obstructing their view. Thus, concealment is the correct terminology for specifically referring to protection from enemy observation.
