What is the definition of a patrol?

A patrol is primarily defined as a unit gathering information or carrying out reconnaissance. This involves conducting operations to observe and monitor the environment, assess enemy presence, gather intelligence, and report back findings to higher command. The essence of a patrol lies in its role to enhance situational awareness and inform strategic decision-making.

Patrols can vary in size and complexity, from small teams operating deep in enemy territory to larger groups covering broader areas. Their main objective is often to obtain crucial information that can help in planning future operations, assessing terrain, or identifying potential threats.

In contrast, the other options focus on different military functions that do not encapsulate the primary purpose of a patrol. While a detachment of ground forces sent to attack refers to offensive operations, a group stationed for defense concerns holding ground rather than actively seeking information. A form of artillery support involves providing firepower rather than gathering intelligence, thus differentiating those functions from the specific role of a patrol.
