What term describes a position or location that is hidden from enemy observation?

The term that accurately describes a position or location that is hidden from enemy observation is "defilade." In military tactics, defilade refers to a position that is protected from enemy fire and observation by terrain features, such as hills or embankments. This strategic use of the landscape allows forces to remain concealed while minimizing vulnerability to direct attacks.

Understanding defilade is crucial for effective battlefield positioning, allowing soldiers to maneuver and operate without being seen and targeted by the enemy. It enhances safety and tactical effectiveness during operations, emphasizing the importance of understanding terrain in military strategy.

While other terms like "concealment" suggest hiding in a manner that may not provide the same level of protection from observation, defilade specifically implies an element of terrain that obstructs both visibility and fire. Therefore, this distinction makes "defilade" the most appropriate choice for describing a position effectively hidden from enemy observation.
