The term "Gray Man" refers to a concept in survival and self-defense strategies where an individual aims to blend into their surroundings to avoid drawing attention. This approach emphasizes wearing neutral clothing, adopting a low-profile demeanor, and minimizing conspicuous behavior, making it harder for others to notice or remember the person. The Gray Man strategy is often discussed in the context of preparedness and urban survival, where individuals may need to navigate potentially dangerous situations without attracting unwanted attention. It is a practical skill for those who prioritize safety and discretion in various environments.
