In terms of terrain analysis, which of the following is evaluated?

In the context of terrain analysis, evaluating site layout is crucial as it examines the arrangement and configuration of features on the ground that can affect tactical operations. The site layout provides insight into how terrain features, such as natural obstacles and man-made structures, can influence movement, visibility, cover, and concealment. Understanding the layout allows military planners to make informed decisions about positioning forces, selecting routes, and optimizing the use of terrain to their advantage during operations.

While environmental factors, route access, and weather analysis are also important aspects of overall operational planning and can influence decisions related to terrain, the specific focus of site layout is directly associated with how terrain can be utilized or exploited in a tactical scenario. Hence, it is a vital component of terrain analysis in a military context.
