What feature describes a 'depression' in terms of terrain?

A depression in terms of terrain is characterized as a low point relative to the surrounding landscape. This definition is essential for understanding how terrain features interact and affect military operations. Depressions can influence visibility, movement, and even the placement of resources or troops. They can serve as natural cover and concealment, making them significant in strategic planning and reconnaissance. Recognizing that a depression is a low area can help military personnel understand the advantages and disadvantages presented by the terrain, such as potential flooding or difficulty in movement due to its lower elevation compared to the surrounding terrain. This understanding is crucial for effective planning and execution in various military scenarios.
