Which method is NOT recommended when handling light and dark spaces?

Moving quickly from light to dark is not recommended because this abrupt transition can increase the risk of being detected by an adversary. When individuals quickly shift from a well-lit area to a darker one, their eyes may not have enough time to adjust to the low light conditions. This can lead to impaired visibility and awareness of the environment, making it difficult to identify threats or navigate effectively.

In contrast, transitioning gradually from dark to light is suggested because it allows the eyes to adjust properly, ensuring better visual acuity and security awareness in new environments. Similarly, ensuring that lights are turned off when moving from light to dark areas prevents giving away one's position, and avoiding silhouettes while using flashlights maintains stealth and reduces the likelihood of being spotted. These strategies collectively enhance safety and effectiveness in a tactical scenario.
