Which term refers to anything that obscures you from enemy observation?

The term that refers to anything that obscures you from enemy observation is "Concealment." This concept is critical in military operations, as it involves hiding personnel, equipment, and activities from enemy observation to avoid detection and minimize the risk of being targeted.

Concealment focuses on obscuring presence through various means such as terrain, structures, or materials that hide or reduce visibility to the enemy. The primary goal is to ensure that opponents cannot see or perceive forces and assets, allowing for greater tactical advantages and strategic movements.

While "Cover" is related to protection from observation and enemy fire, it generally refers to physical barriers like hills or buildings that provide safety rather than just hiding visual presence. "Camouflage" involves using colors and patterns to blend into the environment, which is a technique to achieve concealment but isn't the broad term for anything that obscures observation. "Obfuscation" typically refers to making something unclear or confusing, which is less relevant in a military context regarding physical concealment from observation.

Concealment is therefore the most accurate term that directly describes the act of hiding from an enemy's sight.
