Why is it necessary for patrols to assess terrain before operations?

Assessing terrain before operations is crucial for a number of reasons, primarily focused on ensuring the safety and effectiveness of the patrol. By evaluating the terrain, commanders can plan appropriate routes that consider the physical features of the environment, such as obstacles, elevations, and cover, which can significantly impact movement and positioning. Moreover, understanding the terrain allows for the identification of potential hazards, such as areas that may be prone to ambush or difficult to traverse. This knowledge helps in planning movement strategies, optimizing the use of resources, and making informed decisions that directly affect the success of the mission and the safety of the personnel involved.
