What survival requirement allows you to see but not be seen?

Camouflage is the survival technique that enables individuals to conceal themselves in their environment while maintaining the ability to observe their surroundings. By blending in with the natural features, such as vegetation, terrain, or other elements of the environment, a person can observe without being detected. This principle is essential in military operations where situational awareness is crucial, and remaining hidden from the enemy enhances safety and strategic advantages.

Camouflage differs from other concepts such as cover, which provides physical protection from enemy observation or fire, or disguise, which typically involves altering appearance to mislead an observer. Stealth may refer to broader tactics, including auditory and visual concealment, but in this context, camouflage specifically relates to visual blending with the environment for the purpose of observation.
