What is a common tool used by security officers during their patrols?

A flashlight is a common tool used by security officers during their patrols due to its essential role in ensuring visibility and safety in low-light conditions. Security officers often conduct their duties during nighttime or in poorly lit areas, making a flashlight crucial for spotting potential threats, assessing situations, and navigating dark spaces safely.

In addition to enhancing situational awareness, a flashlight can also serve as a signaling device in emergency situations or to alert others to the officer's presence. Therefore, its functionality directly supports the primary responsibilities of security personnel, which include protecting property and ensuring the safety of individuals within their assigned areas.

Other tools, such as walkie-talkies, body cameras, and first aid kits, serve their own vital purposes but do not have the same immediate utility for visibility and navigation during patrols as a flashlight does.
