What technique involves using objects to limit a person's ability to see you?

The technique that involves using objects to limit a person's ability to see you is concealment. This strategy is crucial in various situations, such as tactical operations or in scenarios requiring stealth. The essence of concealment is to hide oneself from the visual perception of others by leveraging natural or artificial objects, like trees, walls, or other structures, effectively obstructing the line of sight.

This approach does not necessarily provide physical protection from harm, but it is primarily about reducing visibility. In emergency care situations or tactical environments, understanding how to utilize concealment can be essential for maintaining safety, observing a scene, or maneuvering without being detected.

Cloaking, covering, and shielding may imply different strategies or protective measures, but they do not specifically refer to the act of using surrounding objects to hide one's visibility from others in the same way that concealment does.
