A patrol is a systematic journey or movement undertaken by individuals, often in groups, to monitor a specific area. This activity is commonly associated with law enforcement, military, or security personnel who aim to ensure safety and order. Patrols can occur on foot, by vehicle, or even by air, depending on the environment and purpose. The primary goal of a patrol is to observe, deter, and respond to potential threats or incidents. By regularly patrolling areas, such as neighborhoods or parks, authorities like police officers or security guards can maintain a visible presence, which helps to prevent crime and reassure the public.
