What key factor should be considered when selecting a site for operations regarding drainage?

When selecting a site for operations, good drainage is essential because it directly impacts the operational effectiveness and equipment functionality. Proper drainage helps prevent water accumulation, which can lead to various issues such as equipment damage, difficulty in mobility, and hindered communication systems. Ensuring that the site allows for efficient runoff during rain or snowmelt can maintain operational readiness and safety for personnel. Wet or muddy conditions can impede both the manning of equipment and swift movement of troops, making good drainage a critical factor in site selection for military operations.

Choosing a site with poor drainage could lead to standing water, which can create a multitude of logistical challenges, including terrain degradation and increased risk of disease from stagnant water. While flat terrain and elevation may seem advantageous in some scenarios, without good drainage, they may not serve the purpose effectively in the long term.
