What is the primary purpose of a field sketch?

The primary purpose of a field sketch is to provide a quick reference of features. In military operations, field sketches are essential tools that allow personnel to capture and represent the terrain and important landmarks in a concise and easily understandable manner. By creating a field sketch, individuals can record the layout of the area, including natural and man-made features, as well as any tactical points of interest. This quick reference helps soldiers and commanders make informed decisions during planning and execution of operations, especially when time is of the essence and detailed maps may not be readily available.

While documenting distances walked, creating a permanent map, and counting enemy positions are relevant activities during military operations, they do not encompass the primary intent of a field sketch. The focus is on quickly conveying a visual understanding of the environment rather than precise measurement or counting tasks.
